Answer:
x=0.5
y = 10.5
Step-by-step explanation:
y = 3x + 7
y = 5x + 8
3x + 7 = 5x + 8
3x - 5x= 8 - 7
2x = 1
x= 1/2
x=0.5
y = 5x + 8
y = 5(0.5) + 8
y = 2.5 + 8
y = 10.5

Answer:
792 m
Step-by-step explanation:
perimeter of a rectangle = 2l + 2b
⇒ perimeter of ground = (2 x 42) + (2 x 24) = 132 m
Perimeter = 1 round
⇒ 6 rounds = 6 x 132 = 792 m
Answer:
144, 67
Step-by-step explanation:
-8-5y= 12-9y
⇒ 9y -5y= 12+8
⇒ 4y= 20
⇒ y= 20/4
⇒ y= 5
Final answer: y=5~
