Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x - y = 10
2x - y = 7
Step 2: Rewrite Systems
3x - y = 10
Subtract 3x on both sides: -y = 10 - 3xDivide -1 on both sides: y = 3x - 10Step 3: Redefine Systems
y = 3x - 10
2x - y = 7
Step 4: Solve for x
Substitution
Substitute in y: 2x - (3x - 10) = 7Distribute -1: 2x - 3x + 10 = 7Combine like terms: -x + 10 = 7Isolate x term: -x = -3Isolate x: x = 3Step 5: Solve for y
Define equation: 3x - y = 10Substitute in x: 3(3) - y = 10Multiply: 9 - y = 10Isolate y term: -y = 1Isolate y: y = -1The temperature in Tampa increased from 4 a.m. to 4 p.m. on one day in February the tables of values below represents temperatures as a function of time

A family on vacation traveled 180 miles in 3 hours. If their rate of speed was constant,
how many miles did they travel in one hour?
O 180 miles
O 540 miles
60 miles
54 miles
Answer:
Step-by-step explanation:
180/3=60
so 60 miles
Answer:
60 miles
Step-by-step explanation:
Since their speed is constant, you just do 180 miles divided by 3 hours to get 60 miles per hour.
Your boss sends you an email and explains that your fourth location is to Ellis Island to visit the Statue of Liberty. She emails you a scale drawing that one of the architectures in Spain created. On the scale drawing, a scale of 1/61 <—(a fraction) (inches to feet) was used, the height of the statue was 5 inches. How tall is the Statue of Liberty?
(Please explain thoroughly step by step on how you solved the problem.If you can,please provide an image on how you solved the problem.)
Answer:
305 feet
Step-by-step explanation:
We can name the actual height x so we get the equation [tex]\frac{1}{61}x = 5[/tex]. Multiply both sides by 61 to get [tex]x=305[/tex]. The answer would be feet because it wouldn't make sense if the statue of liberty was 305 inches
Maria and Jane set up a lemonade stand one summer to earn money for a trip to the beach. They noticed that the hotter the day, the more glasses of lemonade they sold. They mixed up the lemonade exactly the same way every day: the same amount of sugar, lemon juice, and water. They added ice to the glass when they poured the drink. They always used the same size glass. They decided to chart their sales in order to figure out how much lemonade to make each day, using the weather forecast as their guide. Identify the independent, dependent, and controlled variables in the girls' experimental data.
Answer:
When its hotter people loose water by sweating (de-hydrating) and they replenish their bodies with Lemonade. PLEASE MARK ME BRAINLIEST!!!!!!!!!!!!!!!!!!

Find the distance between the points (-12.3, 15.1) and (17.5, 2). Round your answer to the
nearest hundredth.
Answer:
32.55
Step-by-step explanation:
d = 32.552266
For:
(X1, Y1) = (-12.3, 15.1)
(X2, Y2) = (17.5, 2)
Distance Equation Solution:
d=(17.5−(−12.3))2+(2−15.1)2−−−−−−−−−−−−−−−−−−−−−−−−−√
d=(29.8)2+(−13.1)2−−−−−−−−−−−−−−−√
d=888.04+171.61−−−−−−−−−−−−−√

Divide. Give the Divide. Give the quotient and remainder.
254 divided 8
Quotient:
Remainder:
Step-by-step explanation:
254 = 8 * 30 + 8 * 1 + 6
= 8(30 + 1) + 6
= 8 * 31 + 6.
Hence the quotient is 31 and the remainder is 6.
Answer:
254/8=31.75
Step-by-step explanation:
The remainder of 254 divided by 8 is 6
Determine whether each sequence is arithmetic, geometric, or neither. Then find a formula for the nTh term of the sequence 2/5,3/6,4/7,5/8
Step-by-step explanation:
3/6 - 2/5 = 0.1
4/7 - 3/6 = 0.071
5/8 - 4/7 = 0.053
Since there is no common difference d, the sequence is not arithmetic.
(3/6) / (2/5) = 1.25
(4/7) / (3/6) = 1.14
(5/8) / (4/7) = 1.09
Since there is no common ratio, the sequence is not geometric.
Hence the sequence is neither an AP or GP.
Formula for nth term: (n + 1)/(n + 4).

Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two
sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 9 cm
Answer:
8 cm and 9 cm
Step-by-step explanation:
This is the answer because:
1) The other two sides have to equal somethinng that is bigger than 13.
2) 5 cm + 8 cm = 13 cm, therefore, 5 cm and 8 cm is not the correct answer.
3) 6 cm + 7 cm = 13 cm, therefore, 6 cm and 7 cm is not the correct answer.
4) 7 cm + 2 cm = 9 cm, therefore, 7 cm and 2 cm is not the correct answer.
5) Finally, 8 cm + 9 cm = 17 cm, therefore, it is the correct answer since it has a bigger value than 13.
Hope this helps! :D

A researcher wishes to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used to predict the amount of soil washed away (in kilograms). In this study, the explanatory variable is the
A. amount of eroded soil.
B. rate of water flow.
C. depth of the soil bed.
D. size of the soil bed.
E. None of the above.
Answer:
B. rate of water flow.
Step-by-step explanation:
Given that in a research study the explanatory variable is a form of a variable that is independent and it is used by the researcher to make predictions or analyze variations in other variables known as response variables.
Hence, in this case, the Explanatory variable is the "rate of water flow" because it is the variable researcher wishes to utilize in predicting the amount of soil washed away.

Two cars start from the same point and move in a straight line, one east at a speed of 60 km per hour and the other west at a speed of 80 km per hour. After what time will they live at a distance of 770 km?
Answer:
5.5 hours
Step-by-step explanation:
Given that :
Speed of A = 60 kmphr
Speed of B = 80 kmphr
After what time will distance = 770 km
Speed * Time = Distance
Let time = x
Distance A + Distance B = 770
(60 * x) + (80 * x) = 770
60x + 80x = 770
140x = 770
x = 770 / 140
x = 5.5 hours

i)1-2(2x+1)=1-(x-1)
ii)3.6x-6.1=5.9_2.4x
question from equation and inequality
Answer:
1)Solving the expression [tex]1-2(2x+1)=1-(x-1)[/tex] we get [tex]\mathbf{x=-\frac{1}{3}}[/tex]
2) solving the equation [tex]3.6x-6.1=5.9-2.4x[/tex] we get [tex]\mathbf{x=2}[/tex]
Step-by-step explanation:
We need to solve the expressions:
1) [tex]1-2(2x+1)=1-(x-1)\\[/tex]
Solving
[tex]1-2(2x+1)=1-(x-1)[/tex]
First solving the brackets
[tex]1-4x-2=1-x+1[/tex]
Simplifying
[tex]-1-4x=-x[/tex]
Adding 4x on both sides
[tex]-1-4x+4x=-x+4x\\-1=3x[/tex]
Switching the sides
[tex]3x=-1[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=-\frac{1}{3}\\x= -\frac{1}{3}[/tex]
So, Solving the expression [tex]1-2(2x+1)=1-(x-1)[/tex] we get [tex]\mathbf{x=-\frac{1}{3}}[/tex]
2) [tex]3.6x-6.1=5.9-2.4x[/tex]
Solving:
[tex]3.6x-6.1=5.9-2.4x[/tex]
Adding 6.1 on both sides
[tex]3.6x-6.1+6.1=5.9-2.4x+6.1\\3.6x=12-2.4x[/tex]
Adding 2.4x on both sides
[tex]3.6x+2.4x=12-2.4x+2.4x\\6x=12\\[/tex]
Divide both sides by 6
[tex]\frac{6x}{6}=\frac{12}{6}\\x=2[/tex]
So, solving the equation [tex]3.6x-6.1=5.9-2.4x[/tex] we get [tex]\mathbf{x=2}[/tex]

Top stays the same

Step-by-step explanation:
Of the following sets, which represents a function?
Situation A = {student's name, all the colors that the student likes}
Situation B = {student's name, the student's favorite math teacher}
a. Only A
b. Only B
c. Both A and B
d. Neither A nor B
Answer:
Situation B is a function.
Step-by-step explanation:
We know that,
A function is a relation in which every element in the domain i mapped to a unique element in the co-domain.
That is, every element in the domain must have a unique image.
So, we see that,
Situation A = {student's name, all the colors that the student likes}
Here, the students can have more than one color which they like.
Thus, this relation is not a function.
Situation B = {student's name, the student's favorite math teacher}
Here, the students can have only one favorite math teacher.
So, this relation is a function.

The probability of selecting 3 female employees and 7 male employees to win a promotional trip a company with 10 female and 50 male employees would best be modeled with the _______.
Answer:
The best model is hypergeometric distribution.
Step-by-step explanation:
The probability would be best modeled with hypergeometric distribution.
Hypergeometric distribution is a discrete probability distribution that describes the probability of successes in draws, without replacement, which is often employed in random sampling for statistical quality control.
The hypergeometric distribution differs from the binomial distribution in the lack of replacements.
Thus, the best model is hypergeometric distribution.
