Answer:
7.5!
Step-by-step explanation:
they all add up to 60. divide 60 by 8 and you get 7.5
y = 8 -2x
x + 2 (8 - 2x) = 1
x + 16 - 4x = 1
x - 4x = -15
-3x = -15
x = 5
If x = 5, then we can substitute in...
5 + 2y = 1
2y = -4
y = -2
Now let us check that by substituting those values in to the equation
2x + y = 8
2 (5) + (-2) = 8
That is correct so we have the right values for x and y/
19
418 divided by 22 is equal to 19
Answer: 50 yards by 25 yards
Step-by-step explanation:
rink is also a rectangle
perimeter= 150 yards
length= 2x
width=x
the perimeter of rink is:
p=2(length + width)
150=2(2x + x)
150= 2(3x)
150= 6x
x=150 / 6
x=25
so width is 25 yards and length is twice the width which is 2x
length= 2× 25
length= 50 yards
so the dimension is 50 yards by 25 yards
