How can you express the properties of operations to evaluate this expression 18 + 4(28)
Akimi4 [234]

Answer:

I don't know if I'm understanding your question correctly. But I'll try...

In this problem you need to remember PEMDAS!

Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

18 + 4(28)     -First you would multiply 4 by 28 since the 28 is in parentheses.

18 + 112        -Now you would add to find your answer

= 130

I hope this helps!

Provide in simplest form <br> 12% of 40
AnnZ [28]
To get 10% of 40, you move the decimal point one way to the left. So 10% of 40 is 4
Now you need 2% and because you know 10% is 4, you divide that by 10 and multiply it by 2 because of the 2%
4/10=.4 .4•2=.8
Now you add them
4+.8=4.8
12% of 40 is 4.8
