Y is 7.5
A easy way to do it is simply graph it or divide it!
For instance, since x=5 is half of x=10, we would just divide 15 by 2 to get Y which is 7.5
X is 3
y is 2
you have to replace x with a zero and divide 12 by it and then you do the same for y
Answer:
W = 5 ft; L = 10 ft
Step-by-step explanation:
Start by representing the length and width:
W = W
L = 2W
Area of rectangle = L * W = 2W * W = 50 ft^2. Then 2W^2 = 50 ft^2.
Solving for the width W results in W^2 = 25 ft, or W = 5 ft.
The length, L, is therefore L = 2W = 10 ft.
Check: Does L * W = 50 ft^2? Does (5 ft)(10 ft) = 50 ft^2? YES
Put all number choices in for x.
1+5=6,
3+5=8,
5+5=10,
7+5=12.
The equation says that the answer has to be greater than ten. 6 and 8 are less than ten, and ten is equal to ten, so the only answer is 7, because 7+5=12 :)
