7x + 3 ≥ 52
7x ≥ 49
x ≥ 7
The only graph that works for this one is B, so we don't even need to check the other one.
Answer:
175
the error in the diagram is that it implies Elena read 1/5 of the book, not Andre
Step-by-step explanation:
x= total number of pages
A = 1/5*x
E = A+20 = 1/5*x+20
1/5*x + 20 = 55
1/5*x = 35
x = 35*5 = 175
Answer:
The longer side of the rectangle is 25 yards.
Step-by-step explanation:
The area of a rectangle, A = 100 square yards
The perimeter of a rectangle, P = 58 yards
We formula for area and perimeter of a rectangle is given by :
A = lb
and
P = 2(l+b)
ATQ,
lb = 100 ...(1)
2(l+b) = 58
(l+b) = 29 ....(2)
We need to solve equation (1) and (2).
l = 4, b = 25
So, the longer side of the rectangle is 25 yards.
Answer:
5sqrt(2)
Step-by-step explanation:
you can split 50 into sqrt(25×2)
and the sqrt(25) is 5, so than your left with just the 2 in the sqrt.
