Answer:
x = 41
y = 24
Step-by-step explanation:
Systems of equations is,
-2x - 7y = -250 ------(1)
4x - y = 140 ------(2)
Equation (1) multiplied by 2 then added to equation (2)
-4x -14y = -500
(+) 4x - y = 140
-15y = -360
y =
y = 24
by putting y = 24 in equation (2),
4x - 24 = 140
4x = 140 + 24
x =
x = 41
For x = 41 and y = 24 both the equations are true.
Equation (1), -2(41) - 7(24) = -250 [True]
Equation (2), 4(41) - (24) = 140 [True]

Answer:
x is 90 z is 60 and y is 30
Step-by-step explanation:
Explanation: Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a÷c=b÷c for c≠0
<u><em>First, you divide by 3 both sides of an equation.</em></u>
<u><em>3y/3=24/3</em></u>
<u><em>Then, simplify.</em></u>
<u><em>24/3=8</em></u>
<u><em>8*3=24</em></u>
<u><em>24/8=3</em></u>
<u><em>y=8 is the final answer.</em></u>
<u><em>Hope this helps!</em></u>
<u><em>Thanks!</em></u>
<u><em>Have a great day!</em></u>
Answer:
36 minutes
Step-by-step explanation:
150b / 8m = 18.75b/m we want to know how many bottle of water per minute
675b/18.75b/m = 36m
