Answer:
x < 7
Step-by-step explanation:
-8x + 40 > -16
-8x > -16 - 40
x < -56/-8
x < 7
(when changing sides of neg. multipliers, you need to change the sign side, dont fall for that common mistake)
Answer:
7/12
Step-by-step explanation:
They ate 1/4 and 1/3
1/4 +1/3
Get a common denominator
1/4 *3/3 + 1/3 *4/4
3/12 + 4/12
7/12

Answer:
20 inches
Step-by-step explanation:
Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by
A =1/2(a + b)h where a = length along the top of the cape = 24 in, b = length along the bottom of the cape = 36 in and h = height of the cape
So, h = 2A/(a + b)
= 2 × 600 in²/(24 in + 36 in)
= 1200 in²/60 in
= 20 in
So, the height of the cape is 20 inches
