Question

If 18 : 6 = x : 3 then what is 5 + 3x

Answer 1

32

Explanation:

18 : 6 = 3

therefore, x : 3 has to equal 3.

X : 3 = 3

X = 3 × 3

X = 9

To verify:

18 : 6 = 9 : 3

3 = 3

It's true that X = 9, so now just replace the X with 9 in the next equation

5 + 3(9) = 32

Answer 2

32

Explanation:

18 : 6 = x : 3

Product of means = Product of extremes

6 * x = 3*18

x =
`(3*18)/(6)`

x = 3*3

x = 9

Now plugin x = 9 in the expression

5 + 3x = 5 + 3*9

= 5 + 27

= 32
