Answer:
l=11.25 (total of both lengths, you divide that by 2 for one side.)
Step-by-step explanation:
l*w=20 ft
l=w+2 1/2 ft
w+2 1/2 *w= 20
-2 1/2
2w=17 1/2
divide by 2
w=8.75 l= 11.25
8.75+2.5 = 11.25
Answer:
5/6
Step-by-step explanation:
Numbers greater than 1 are 2, 3, 4, 5, 6

Answer:
Step-by-step explanation:
We need a system of equations for this. The first sentence in the problem tells us the first equation. "Sum" means we are adding, "is" means equals. Therefore, the first equation is
x + y = 10.3
The second sentence tells us the second equation. "Difference" means to subtract. Therefore, the second equation is
x - y = 2.84
It would be best to solve this by elimination (also called addition). Line them up one over the other so the variables also line up:
x + y = 10.3
x - y = 2.84
And as you see, when you add straight down, the y's eliminate each other, leaving us with
2x = 13.14 and divide by 2 to get that
x = 6.57
Now plug that in for x to solve for y in either one of the equations. I'll use the first one:
6.57 + y = 10.3 so
y = 3.73
