Step-by-step explanation:
the answer is
(2x+13)=(3x-3)
x= 16
Alright so to find the area of a rectangular prism (a book is a rectangular prism) you need to multiply the 3 numbers they give you so you multiply 7, 812, and 2/12. after you multiply all of the numbers you add ^3 to the end because you found the volume, its not a flat shape or a 2D shape.
Answer y=mx+b
Step-by-step explanation: b is the y intercept and x is the slope
60 - 18 = 42
42/60 x 100 - 70%
To check this do 0.7 x 60 (which gets you 18, so it is right)
Answer:
{-infinity, infinity}
no solution
Step-by-step explanation:
|x| +15≥4
Subtract 15 from each side
|x| +15-15≥4-15
|x| ≥-11
This is always true so x can be and real number
{-infinity, infinity}
-2|5x+3| = 8
Divide by -2
-2/-2|5x+3| = 8/-2
|5x+3| = -4
This can never happen because absolute values are zero or greater
no solution
