Answer:
A
Step-by-step explanation:
Area of rectangle = length x width
length = 5x - 2
width = x
area = (5x - 2) × x
100 = 5x² - 2x
the width would be less than the area of the rectangle, thus the inequality sign to be used is <
5x² - 2x < 100
Answer:C
Step-by-step explanation:
Answer:
Step-by-step explanation:
5x -x + 3x =30, first you combine like terms 5x + 3x-x=30
8x-x =30
8-1=7
7x=30
Multiply 120 by .7 then take the product and add it to 120.
