3 (10x+7) is equal to 30x+21
Answer: option B is the correct answer
Step-by-step explanation:
Candace's backyard has a flower garden that covers 40% of her backyard.
If the total area of her backyard is 450 square feet, it means that her garden covers 40% of 450 square feet.
To determine how many square feet is her flower garden, we will find the value of 40% of 450 square feet. It becomes
40/100 × 450= 0.4×460 = 180 square feet
Answer:
3,6
Step-by-step explanation:
x+y=9
x-y=-3
Adding these two equations we get 2x = 6, x=3
y=6
(3x+7)(x-1)=0
3x+7=0
x= -7/3
x-1=0
x=1
You need to solve the equation for h.
<span>W= 50+2.3(h-60)
Distribute the 2.3.
W = 50 + 2.3h - 138
W = 2.3h - 88
Add 88 to both sides.
W + 88 = 2.3h
Switch sides.
2.3h = W + 88
Divide both sides by 2.3.
h = (W + 88)/2.3
