Question

plz i need help :(

which expression completes this equation?
36/4-2*3=?
A.[18-(10-6)]+1
B.{(8-6)*3}/2
C.36-2*3
D.3*6-4/2

Answer 1

Do you know the order of operations?

Answer 2

PEMDAS - Parentheses, exponent, multiplication, division, addition, subtraction.

Answer 3

yes

Answer 4

Ok, so use the order of operations to solve the equation. First, you do multiplication: -2*3

Answer 5

-6

Answer 6

Good.

Answer 7

Next, do division: 36/4

Answer 8

9

Answer 9

Wait, is this asking for you to find an equivalent equation to that? Because, that can also be done. The solved answer just isn't there, so apparently we have to find an equivalent expression to that.

Answer 10

?

Answer 11

So, I am guessing that we have to find an equation that equals to the given, with PEMDAS

Answer 12

i guess so

Answer 13

It would not be a, because it is [18 - 4] + 1.
For b, it is {(8-6)*3}/2. Which is [2*3]/2. 6/3 = ?

Answer 14

so it's b?

Answer 15

Yes, but let's check the other 2 first.
C.36-2*3 --> 36 - 3 = 30.
D.3*6-4/2 --> 18 - 2 --> 16

Answer 16

So yes, it is b.

Answer 17

thx

Answer 18

Any time.
