Answer:
The answer for this question would be
t + (-22)
Explanation:
The LCD of these fractions is 40 which is already stated in the answer choices.
3/4 would turn into 30/40
2/5 would turn into 16/40
You could already solve for the first parentheses which would turn into 46/40 - 5
For the second parentheses you have to multiply the subtraction sign (-) to the equation 5/8t + 17 and this would turn into -5/8 - 17. Then you want it to have the LCD 40 so -5/8 would turn into -25/40.
Putting the parentheses together in would be (46/40t - 5) + (-25/40t - 17)
46/40 + (-25/40) = 21/40
-5 + -17 = -22
Lastly, you just add it together to give you 21/40t + (-22)
