Answer:
12 and 10
Step-by-step explanation:
I used just x and y for the two different variables

22= x+y
44 = x^2 - y^2
its a simultaneous equation now, so you're able to use that from there

Answer:
1 1/7 miles
Step-by-step explanation:
Since Kenny can run 2/7 of a mile in 1/4 of a hour we can multiply 2/7 by 4 and we end up with 1 1/7 miles ran.
Length (L): w + 3.5
width (w): w
Perimeter (P) = 2L + 2w
31 = 2(w + 3.5) + 2(w)
31 = 2w + 7 + 2w
31 = 4w + 7
24 = 4w
6 = w
Length (L): w + 3.5 = (6) + 3.5 = 9.5
Answer: width = 6 inches, length = 9.5 inches
B. -9 is the most negative one, -2 is the least.
