Since the first number is 1, it will remain 1 at the end. So we have to find the bottom number to the power of four.
This can be simplified to equal
Which equals to 16. So we know the final equation will be equal to
1/16
His claim is reasonable because 154÷25 6.16
6.16×2= 12.32 so it would be 12 dollars off!
2x-25=x+5
x=30
30+5=35
180-35=145
9y+28=145
9y=117
y=13
I hope help you this question
