Negative plus a negative is always positive. positive plus a positive is a positive. but if you have an positive plus a negative whatever sign has the bigger number thats the sign you'll use.
It would be $75.
Becuase, $15 divided by 2 years equals $7.50 a year.
Therefore, $7.50 X The 10 years would be $75.
Hope that helped.
Answer:
if you were solving for X the answer would be x < 3
Step-by-step explanation:
Answer:
x = -7
Step-by-step explanation:
3(x+7) = -15
First, distributive property. Therefore, you multiply 3 with x and 7
3x + 21 = -15
Then, you need x to be isolated. So you will have to -21 from +21 on both sides of the equation to make it balanced.
3x + 21 = -15
<u> -21 -21</u> (21 will be canceled from the left side of the equation)
3x = -35
Lastly, you need to divide 3 from both sides of the equation, as 3 is multiplied with x.
<u>3x</u> = <u>-35</u>
3 3 (3 will be canceled from the left side of the equation)
<em><u>x = -7</u></em>
