Answer: 4 9/10
Step-by-step explanation: You need to subtract 12 2/5 and 7 1/2.
The two fractions have different denominators. Multiply to find a common denominator
2/5 x 2/2 = 4/10
1/2 x 5/5 = 5/10
Now you have 12 4/10 minus 7 5/10. But you cannot subtract 4/10 and 5/10 equally.
Subtract 12 - 1 and add 1 to 4/10.
12 - 1 = 11
10/10 (10/10 is 1) + 4/10 = 14/10
Now you have 11 14/10 minus 7 5/10. Subtract.
11 - 7 = 4
14/10 - 5/10 = 9/10
That makes 4 9/10.
Hope this is helpful :)
It would be the first box, when multiplying exponents, you add the exponents and just keep the base. So it be 2^17

I hope this helps!!
2.75 hours.
The equation would be 32x + 46 = 134. So we subtract 46 from 134 and get 88. Now we have to divide that by 32 to get the total of 2.75 hours
