Question

x/6 = 4 , r/7 = -1 , -x/11 = 10 , x/4 = 5/6 i totally forgot how to do these problems, it'd be lovely if someone could help me out :)

Answer 1

1. x = 24

2. r = -7

3. x = - 110

4. x = 10/3

Explanation:

1. x/6 = 4 => x = 6 · 4 = 24

2. r/7 = -1 => r = -1 · 7 = -7

3. -x/11 = 10 => -x = 11 · 10 = 110 => -x = 110 / ·(-1)

Now we will multiply the both sides with (-1) and get

x = -110

4. x/4 = 5/6 It's the same as proportion x : 4 = 5 : 6

Now we will multiply external and internal members and get

6 x = 4 · 5 => 6 x = 20 => x = 20/6

Now we reduce the numerator and the fractional denominator with the number two and get

x = 10/3

God with you!!!
