7.5+13.6=12.4+[]
work out the missing number

Lets take, Missing number as = x

7.5+13.6 = 12.4+x

21.1 = 12.4+x

21.1 - 12.4 = x

x = 8.7

Re-check:-

=> 7.5+13.6 = 12.4+8.7

=> 21.1 = 21.1

8.7

Step-by-step explanation:

I'm gonna use algebra for this if you don't mind.

7.5 + 13.6 = 21.1

21.1 = 12.4 + x

Subtract 12.4 from both sides:

21.1 - 12.4 = 12.4 - 12.4 + x

8.7 = x

Reasoning:

First add 7.5 and 13.6 to get 21.1.

You'll get something that looks like this: 21.1 = 12.4 + _

We want a number that adds to 12.4 to make 21.1, so we subtract 21.1 from 12.4 and we get 8.7

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
