Question

OMG I don't understand any of this

Answer 1

The answer would be 21/4 t + (-22)

Answer 2

The answer for this question would be
`(21)/(40)`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)
