Answer:
the 3rd choice, 10x + 5, looks good
Step-by-step explanation:
a coefficient is the number in front of a variable , so that's 10
a constant is a number w/o a variable ... so that's 5
I believe that the answer is 10x + 5.
Coefficents are also know as "multipliers". They pair with variables (in this case, that is x). Constants are simply numbers on their own.
Hope that makes sense.

Answer:
Option B
Step-by-step explanation:
Question 7
1). √14 + 6.2 < 3π - 8.2
Since, 14 is the nearest whole square number to 16
√14 ≈ √16 ≈ 4
Similarly, π ≈ 3.14 ≈ 3
By substituting these approximate values in the inequality,
4 + 6.2 < 3(3) - 8.2
10.2 < 9 - 8.2
10.2 < 0.8
False.
2). [tex]\frac{17}{5}+\sqrt{64}>8+\pi[/tex]
[tex]\frac{17}{5}+8>8+\pi[/tex]
3.4 + 8 > 8 + 3.14
11.4 > 11.14
True.
3). 35 - √40 > 6π
[Since, nearest whole square integer to 40 is 36 and π ≈ 3]
35 - √36 > 6(3)
35 - 6 > 18
29 > 18
True.
Therefore, Option B is the correct option.

Wendy spends 3/5 of her money on 3 bowls and 8 plates. With the rest of your money, you can buy another 6 bowls. If you spend all your money just on plates, how many plates can you buy?
Answers
answer: 16 plates
I apologize if this is an incorrect answer,however, I believe that the fraction was added to throw you off. so if you divide the number of bowls you get 2 and then you multiply 8 by 2
If you spend all your money just on plates. Then the number of plates that you can buy will be 20.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Wendy spends 3/5 of her money on 3 bowls and 8 plates. With the rest of your money, you can buy another 6 bowls.
Let 'x' be the cost of each bowl, 'y' be the cost of each plate, and 'T' be the total amount of money. Then the equations are given as,
3x + 8y = (3/5) T ...1
6x = (2/5) T
x = (1/15) T ...2
From equations 1 and 2, then the cost of each plate is calculated as,
3(1/15)T + 8y = (3/5)T
8y = 2/5
y = (1/20)T
If you spend all your money just on plates. Then the number of plates that you can buy will be given as,
⇒ T / (T / 20)
⇒ 20

Answer:
a. $2480b. $4040c. 4 years and 2 monthsd. 8 years and 4 monthsStep-by-step explanation:
a. Account after 4 years:
2000 + 4*2000*0.06 = $2480b. Account after 17 years:
2000 + 17*2000*0.06 = $4040c. Time when account = $2500:
2000 + x*2000*0.06 = 2500120x = 500x = 500/120x = 4 20/120 = 4 2/12 years = 4 years and 2 monthsd. Time when account = $3000

Kia buys a shirt that costs $12.50 and some pairs of socks that are $2.50 each. She pays a total of $27.50 How many pairs of socks did Kia buy? Write your solution in a complete sentence.
Answers
Answer:
6
Step-by-step explanation:
Given that:
Cost of shirt = $12.50
Cost per socks = $2.50
Total amount paid = $27.50
How many pairs of socks was purchased =?
Let Number of socks purchased = x
Total amount paid = cost of shirt + (cost per socks * number of socks)
27.50 = 12.50 + (2.50 * x)
27.50 = 12.50 + 2.50x
27.50 - 12.50 = 2.50x
15 = 2.50x
x = 15 / 2.50
x = 6
Number of pairs purchased = 6
Find the x-intercept and y-intercept of the line. -3x+6y=11
Answers
Answer:
x- intercept is at [tex]( - 3 \frac{2}{3} ,0)[/tex].
y- intercept is at [tex](0,1 \frac{5}{6} )[/tex].
Step-by-step explanation:
The x-intercept occurs when y=0.
Thus, substitute y= 0 into the equation to find the x- intercept.
-3x +6y= 11
When y= 0,
-3x +6(0)= 11
-3x= 11
x= 11 ÷ (-3)
[tex]x = - \frac{11}{3} \\ x = - 3 \frac{2}{3} [/tex]
The y-intercept occurs at x= 0.
When x= 0,
-3(0) +6y= 11
6y= 11
y= 11÷ 6
[tex]y = 1\frac{5}{6} [/tex]
