Substitute y = 15x to the equation y = 25 + 12.5x:
15x = 25 + 12.5x <em>subtract 12.5x from both sides</em>
2.5x = 25 <em>divide both sides by 2.5</em>
x = 10
Substitute the value of x to the equation y = 15x:
y = (15)(10)
y = 150
<h3>
Answer: x = 10 and y = 150</h3>
3(x + 2) + 4(x - 5) = 10
Use the distributive property:
3x + 6 + 4x - 20 = 10
Combine like terms:
7x -14 = 10
Add 14 to both sides:
7x = 24
Divide both sides by 7:
x = 24/7
Answer:
I think you would have to add 12.5 to the 5
Step-by-step explanation:
Answer:
15%
Step-by-step explanation:
Since a percent is out of 100 we can make 75/500 to have the denominator of 100.
To do that you divide
500/5 = 100
and for the numerator
75/5 = 15
whatever you do to one side you must do to the other that's why I divided both sides by 5. The ending fraction would be 15/100 which is the same as 15%
Hope that helps and have a great day!
