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!

Vivenne, John and nassim ran for 6th grade class president. Vivenne got four votes for every 3 votes that John got. Nassim got t
liq [111]

Answer:

John received 10% of the overall votes.

Step-by-step explanation:

Let us assume that the number of votes John got  = m

So, the number of votes Vivienne received =   3 times (John's share )

 = 3  times m   =  3 m

Also, The number of Votes Nassim received = 2 times ( Vivienne's share)

2 x (3 m)   = 6 m

Total Votes in the grade 6  

= Votes received by { John + Vivienne + Nassim}

= m + (3 m) + (6 m) = 10 m

Hence, the total number of students who voted in grade 6  = 10 m

\textrm{The percentage of John's Votes }  = \frac{\textrm{Number of votes John received}}{\textrm{Total number of votes }}  \times 100

= \frac{m}{10m}  \times 100 = 10

or, The percentage of John's Votes  = 10%

Hence, John received 10% of the overall votes.
