Answer:
X= 18
Step-by-step explanation:
-133 + 8x = -5x +101 solve for x
Combine like terms
8x + 5x = 101 + 133
13x = 234
x = 18
Answer:
They exceed their goal by $150.
Step-by-step explanation:
If x = weekday shows and y = weekend shows, then
50(15) + 150(6)
750 + 900 = 1650
1650 - 1500 = 150
Answer:
81m+27t
Step-by-step explanation:
We need to distribute the 9 to the terms inside the parentheses:
9(9m+3t)=9(9m)+9(3t)=81m+27t
Answer:
$2000x(1.03)ˣ
Step-by-step explanation:
This is known as compound interest.
100% + 3% = 103%, so we put this into a decimal: 1.03
We now put this into the equation:
$2000x(1.03)ˣ
If you want to work out the price after, say 3 years, then you would change x to 3, so the equation becomes
$2000x(1.03)³
You can then use a calculator to work out the answer.
