Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
Answer: easy peasy so your answer would be 4=(6x7)x12 so what you would do is take the first two and dived them your answer you want to dived it with your other numbers
Step-by-step explanation:
=2/3 x 4 1/5
Change 4 1/5 to improper fraction
=2/3 x 21/5
Multiply the two numerators together and multiply the two denominators together
= (2*21)/(3*5)
=42/15
Convert back to mixed fraction
= 2 12/15
Simplify by dividing 3 into top & bottom
ANSWER:
= 2 4/5 simplest mixed fraction

Answer:
<h2>The answer is 75 and 75</h2>
Step-by-step explanation:
hope this helps!!
Write a system of equations:
x + y = 125
20x + 15y = 2100
Solving:
x = 125 - y
20(125 - y) + 15y = 2100
2500 - 20y + 15y = 2100
2500 - 5y = 2100
-5y = 2100 - 2500
-5y = -400
y=80
x + 80 = 125
x = 125 - 80
x = 45
The first charges 45$ per hour and the second charges 80$ per hour
