Step-by-step explanation:
The sum of two opposite interior angles equals an exterior angle
50+?=115
?=115-50=65°
Answer:
Step-by-step explanation:
(7/8) to the negative power is 8/7
6(2x - 11) + 15 = 21
First step use distributive property on the left side to remove the parenthesis, to do this multiply 6 by each term inside the parenthesis:
12x - 66 + 15 = 21
Second step, simplify the left side by combining the like terms:
12x - 51 = 21
Third step, add 51 to both sides of the equation:
12x = 72
Last step, divide both sides by 12:
x = 72/12
x = 6
First reduce it.
10:7 In a sense that is about as far down as you can go
You could however make it 1 3/7 to 1
Quotient=19
remainder= 3
or
mixed number = 3/35
