Answers

Answer:

A

Step-by-step explanation:

15^2 = 225 (memorize everything to 20, thank me later)

39^2 = 1521 (just use a calculator for everything higher)

225 + 1521

1521 =?= 45^2

45^2 = 2025

1521 =/= 2025

Just to be sure, I'll do 15^2 + 45^2 (going to be too much)

225 + 2025 = 2250

2250 =/= 1521
The answer would be a

Liam had $250. Then, he and his classmates bought a present for their teacher, evenly splitting the $120 among the e of them. How much money does Liam have left? Write your answer as an expression.

Answers

Answer:

250-(120)/(e)

Step-by-step explanation:

We have been given that Liam and his classmates bought a present for their teacher, evenly splitting the $120 among the 'e' of them.

This means that number of all students is 'e'. To find the cost of present for each student, we will divide 120 by e.

\text{Cost of present for each student}=(120)/(e)

Since Liam had $250, so we need to subtract (120)/(e) from 250 to get amount Liam has left:

\text{Amount Liam has left}=250-(120)/(e)

Therefore, our required expression would be 250-(120)/(e).
Liam Splits $40 With The 3 Of Them Out Of $120 And Liam Has 130 Because 250-120=130
