Answer 1

Answer:

1. 7 + 14 + x = 5 + 10 + 8

First, you would add what you already know

= 21 + x = 23

Then, you would subtract 21 from both sides to isolate the x

= x = 2

There's your answer x = 2

2. First, you should find the original number.

First, multiply the number by 3 (because the numerator is 3) which equals 108

Next, you would divide that number by 4 (the denominator) which is 27.

27 is the original number. To find 1/3 of that, just divide it by 3

27/3 = 9

3. To get the answer, all you need to do is multiply 25 by 4 (because 25 x 4 = 100) and 11 by 4.

25 x 4 = 100

11 x 4 = 44

Next you would subtract the two

100 - 44 = 56.

That's your answer = 56
