Answer:

51.

Step-by-step explanation:

When we use PEMDAS, we need to know what it stands for first. What it stands for will give us the steps necessary to complete and solve this problem.

PEMDAS stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.

In this problem we do not have parenthesis or exponents, so we can go ahead and skip to multiplication. So:

8 x 18 ÷ 4 + 15

144 ÷ 4 + 15

Now we can go to doing division.

144 ÷ 4 + 15

36 + 15

Now we can do addition.

36 + 15

So, the answer is 51.

I hope that this helps.

A sum of money is divided amongst Farah, Shaiyara and Zahin in the ratio 10: 7: 5. If
r-ruslan [8.4K]

Answers:

  • Total amount of money =  220 dollars
  • Amount Farah gets = 100 dollars

==========================================================

Explanation:

  • F = amount Farah gets
  • S = amount Shaiyara gets
  • Z = amount Zahin gets

The money is divided in the ratio 10:7:5

This means that

  • F = 10x
  • S = 7x
  • Z = 5x

for some positive real number x.

Since Shaiyara gets $20 more than Zahin, we can say,

S = Z+20

Let's plug in S = 7x and Z = 5x and solve for x

S = Z+20

7x = 5x+20

7x-5x = 20

2x = 20

x = 20/2

x = 10

Therefore,

  • F = 10x = 10*10 = 100
  • S = 7x = 7*10 = 70
  • Z = 5x = 5*10 = 50

The ratio F:S:Z becomes 100:70:50 which reduces fully to 10:7:5 after dividing all three parts by the GCF 10.

The total sum of money shared is 100+70+50 = 220 dollars and Farah gets $100 of that total.
