Answer:
2x+30
Step-by-step explanation:
The perimeter of a rectangle is
P = 2(l+w)
The length is 2/3 x+10 and the width is 1/3x +5
P = 2(2/3x +10 + 1/3x +5)
Combine like terms
P = 2(2/3x + 1/3x +10+5)
= 2(x +15)
Distribute the 2
= 2x+30
Answer:
11 hours
Step-by-step explanation:
let he works at first store x hours and at car wash y hours. Then
x+y=25
multiply by 4
4x+4y=100 ...(1)
12x+15y=333
divide by 3
4x+5y=111 ... (2)
(2)-(1) gives
y=111-100=11
Answer:
1) 147
2) 87
Step-by-step explanation:
1) Area of triangle = × base length × height
=
× 14 × 10
= 70 
Area of a semicircle =
( r is the radius)
Radius = half of diameter =
= 7m
Area of semicircle = 
= 77
( Nearest whole number )
Total area = 77 + 70 = 147
2) Divide the shape into 2 rectangles
Area of a rectangle = length × width
Rectangle 1 = 7 × ( 3+3+5 )
= 7 × 11 = 77
Rectangle 2 = 2 × 5
= 10
Total Area = 77 + 10 = 87
