Answer:
x ≤ 5
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define Inequality
4x - 2 ≤ 18
Step 2: Solve for x
Add 2 to both sides: 4x ≤ 20Divide 4 on both sides: x ≤ 5Here we see that any value x smaller than or equal to 5 would work as a solution to the inequality.
In the year 2010, a person bought a new car for $26000. For each consecutive year after that, the value of the car depreciated by 10%. How much would the car be worth in the year 2014, to the nearest hundred dollars?
Answer:
$17,100
Step-by-step explanation:
Set up an equation where y is the worth of the car and t is the number of years since 2010:
y = 26000(0.9)^t
Plug in 4 as t, since it is asking about 2014:
y = 26000(0.9)^t
y = 26000(0.9)^4
y = 17058.6
Round to the nearest hundred dollars:
17058.6
= 17,100
So, the car will be worth approximately $17,100

A shirt is priced at $12. What is the price after a 15% discount and 7% sales tax?
the total, end price is $10.91
15% of 12 = 1.8 which makes it 10.2
7% of 10.2 = 0.714 which makes 10.91
the end price is $10.91

if ordered pair (k, -3) lies on the graph of 5x - 2y = -24 then what is the value of k
Answer:
given,
(x y)= (k -3)
so ,
5x- 2y= -24
or, 5k +6 =-24
or,5k =-24 - 6
or,5k= -30
therefore,
k=-6

Here's a graph of a linear function. write the equation that describes that function.
Answer:
y = 1/4x + 5
Step-by-step explanation:
Here, we want to write the equation of the function
Generally we can have the equation of a straight line as;
y = mx + b
m is slope, b is the y-intercept
From the graph we have the y-intercept as 5
To get the slope, we select any two points and apply the slope formula
Let us have the points;
(8,7) and (4,6)
the slope will be;
m = (y2-y1)/(x2-x1) = (6-7)/(4-8) = 1/4
So the equation of the line is;
y = 1/4x + 5

Ms. Semuskie is buying bagels for her family. How many bagels can she buy for 50$
Answer:
40 bagels
Step-by-step explanation:
Let us assume that the cost of each bagel is $1.25
We need to find how many bagels she can buy for $50.
Let she can buy x bagels.
[tex]1.25\times x=50\\\\x=\dfrac{50}{1.25}\\\\x=40[/tex]
Hence, she can buy 40 bagels for $50.
a coin is tossed 100 times. Which is the best estimate for the number of times the coin will land heads up?
Answer:
50
Step-by-step explanation:
There is a 50-50 chance the coin lands heads up. Of course, if you flip a coin 100 times, it will not be exactly 50, but it will be pretty close.
Answer:
It is 50% likely because there is a 50/50 chance on both heads and tails
Step-by-step explanation:

Ms. Buback is competing in a race in which she both runs and rides a bike. She runs 5 kilometers in 0.5 hours and rides her bike 20 kilometers in 0.8 hours. At the rate given, how many kilometers can she bike in one hour?
Answer:
25.02 km/h
Step-by-step explanation:
60 min × 0.8 = 48 min
20 km÷48 = 0.417 km/min
0.417 × 60 = 25.02 km
Solve for X-B(5,0.85), for x = 3.
Answer:
Solve for X-B(5,0.85), for x = 3.*25*
delete my question if it's wrong
The value of the expression is,
X = 0.138
We have to give that,
An expression is,
⇒ X ~ B (5, 0.85)
for, x = 3
Now, simplify the expression for x = 3 as,
X = ⁵C₃ (0.85)³ (1 - 0.85)³⁻¹
X = (5!/3!2!) (0.85)³ (1 - 0.85)²
X = 10 × (0.85)³ (0.15)²
X = 0.138
Hence, The value of the expression is,
X = 0.138

The surface area of a cube is represented by the expression below, where s is the side length of the cube. Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.
Answer:
486 centimeters³
Step-by-step explanation:
Surface area of a cube = 6s²
Where,
s = side length
Find the surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters.
s = 9 centimeters
Surface area of a cube = 6s²
= 6 × 9²
= 6 × 81
= 486 centimeters³
Surface area of a cube-shaped jewelry gift box with a side length of 9 centimeters 486 centimeters³

Answer:
10) 15,794
11) 20,306
Step-by-step explanation:
10) Sin(33) = x÷29
Multiply with 29 on both sides.
x = Sin(33) × 29 = 15,794
11) Tan(55) = 29÷x
Multiply with x on both sides.
xTan(55) = 29
Divide with Tan(55) on both sides.
x = 29 ÷ Tan(55) = 20,306
chuck was chopping wood.when he was done he had 25 kg of firewood what was most likely the weight of the wood before he chopped it
Answer:
The weight of the wood before he chopped it is 245 N
Step-by-step explanation:
The law of conservation of mass states that for a given isolated system, mass (or matter) can not be created neither can it be destroyed, but it can be transformed into different forms
Therefore, whereby all the wood Chuck chops is taken as firewood, (wood which is dry is about 100% consumable as firewood) the mass of the wool before he chopped the wood = The mass of the firewood he had after chopping the wood = 25 kg
Weight = Mass × The acceleration due to gravity, g
g = Constant = 9.8 m/s²
The weight of the wood before he chopped it = 25 kg × 98 m/s² = 245 N.
Answer:
as much as it wants

#2: Given the geometric sequence 200, 100, 50, 25... (This one is tricky)
Write the explicit formula.
• Determine the 15th term of the sequence?
Answer:
see explanation
Step-by-step explanation:
The explicit formula for a geometric sequence is
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 200 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{100}{200}[/tex] = [tex]\frac{1}{2}[/tex] , then
[tex]a_{n}[/tex] = 200 [tex](\frac{1}{2}) ^{n-1}[/tex] ← explicit formula
The 15 th term is then
a₁₅ = 200 × [tex](\frac{1}{2}) ^{14}[/tex]
= 200 × [tex]\frac{1}{16384}[/tex]
= [tex]\frac{200}{16384}[/tex] ← divide numerator/ denominator by 8
= [tex]\frac{25}{2048}[/tex]
3/4 divided by 1/5

O x + 12
0 2x + 12
O
*226
Given:
The expression is
[tex]2(10)+2(x-4)[/tex]
To find:
The simplified form of the given expression.
Solution:
We have,
[tex]2(10)+2(x-4)[/tex]
Using distributive property, we get
[tex]=20+2(x)+2(-4)[/tex]
[tex]=20+2x+(-8)[/tex]
[tex]=20+2x-8[/tex]
On combining like terms, we get
[tex]=2x+(20-8)[/tex]
[tex]=2x+16[/tex]
Therefore, the correct option is A.

Answer:
The answer is 7600 because in order to reach negative coordinates you have to travel the length to 0 then down the scale to -1, -2, -3, and so on and vice versa to get to positive coordinates.
