45/x =15/100
Cross multiply
15x=4500
Divide both sides by 15
X=300
300 total cars on parking lot
Answer:
To factor something out you've got to divide, so you would take 5x+40 and divide it all by 5
So, 5x/5= 1x
And, 40/5= 8
Your answer is now x+8 when factored
Answer:
3 x + 14
Step-by-step explanation:
Simplify the following:
6 x - 3 x - 11 + 25
Grouping like terms, 6 x - 3 x - 11 + 25 = (6 x - 3 x) + (-11 + 25):
(6 x - 3 x) + (-11 + 25)
6 x - 3 x = 3 x:
3 x + (-11 + 25)
25 - 11 = 14:
Answer: 3 x + 14
Answer:
18
Step-by-step explanation:
1.80 x 10 = 18.0
:)
The line is parallel so it has the same slope as the other line, -4.
Substitute the x and y variables with the given points and find the y-intercept.
(-8, 6)
y = -4x + b
6 = -4(8) + b
6 = -32 + b
6 + 32 = b
38 = b
So the equation is:
y = -4 + 38
