Answer:
w = 6
Step-by-step explanation:
5w-26 = - 4 (w - 7) multiply -4 through
5w - 26 = - 4w + 28 add 4w to each side to cancel it out on the right
5w + 4w - 26 = 28
9w - 26 = 28 Now add 26 to each side
9w - 26 + 26 = 28 + 26
9w = 54 Now divide each side by 9
(9w)/9 = 54/9
w = 6
Answer:
A = 78.5
C = 31.4
Step-by-step explanation:
Circumference = 2πr
r = 5
C = 2(3.14)(5)
Circumference = 31.4
Area = 
r = 5
A = 
<span>A will states that 5/6 of an estate is to be divided among relatives.
Of the remaining, 1/2 goes to charity. How much goes to charity?
</span><span>Remaining will be 1/6
1/6 * 1/6 = 1/36 goes to charity

Answer:
19 m
Step-by-step explanation:
Perimeter = 2(length + width) ; P = 2(l+w) - - (1)
Area = Length * width ; A = l*w - - - (2)
76 = 2(l+w)
76/2 = l+w
l+w = 38
l = 38 - w
Put l = 38 - w in (1)
A = (38-w)*w
A = 38w - w²
At maximum point:
dA/dw = 0
dA/dw = 38 - 2w
38 - 2w = 0
38 = 2w
w = 38/2
w = 19
