70-2(40÷8)-4=

Hello from MrBillDoesMath!

Answer:

Discussion:

In the order of operation, parentheses comes before subtraction so the expression equals

70 - 2 (5) - 4 => as 40/8 = 5

= 70 - 10 - 4

= 60 - 4

I believe the first respondent gave the same answer -- I just wanted to supply a few more steps for you

Thank you,

MrB

Evaluate x+2.7 for x=-1.5

jonny [76]

Answer:

1.2

Step-by-step explanation:

First make -1.5 equal to 0.

We'll have to add 1.5, right?

So 1.5 is in 2.7.

So now its 0 + ? = ?

2.7 - 1.5 = 1.2

So 0 + 1.2 = 1.2

Hope this helped.
