25% — $40
100% — $40 * 4 = $160
The original price is $160.
Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7
Answer:
For x it would be 50 m2
Step-by-step explanation:
Since 4 is between 2 & 5 you input it into the middle equation.
x=4
so the answer is 4!
4(x+2)+2=14
4x+8+2=14
4x+10=14
Subtract 10 from both sides
4x=4
Divide by 4 on both sides
x=1
