Answer: x=12

Step-by-step explanation:

The two angles provided are on a straight line

A straight line is 180 degrees, so we can add the two angles to make 180 and solve for x

$10x-20+6x+8=180$

Simplify

$10x-20+6x+8=180\\10x+6x-20+8=180\\16x-12=180$

Add 12 on both sides

$16x-12=180\\16x-12+12=180+12\\16x=192$

Divide both sides by 16 to isolate x

$16x=192\\\frac{16x}{16} =\frac{192}{16} \\x=12$

karen brought 3/8 of a gallon of ice tea to a party. Robin brought 15/16 of a gallon of ice tea to the same party. How much ice

Rudiy27

Answer:

1 5/16 gallon

Step-by-step explanation:

Gallon of ice brought by Karen = 3/8

Gallon of ice brought by Robin = 15/16

Total ice team brought by them is sum of Gallon of ice brought by Karen + Gallon of ice brought by Robin

Total ice team brought by Karen and Robin = 3/8 + 15/16

=> 3*2/8*2 + 15/16

we are multiplying with 2 both numerator and denominator in 3/8 so sas the denominator becomes 16 as in other fraction denominator is 16

=> 6/16 + 15/16

=> (6+15)/16 = 21/16

since 21/16 is improper fraction, converting it in mixed fraction we have

21/16 = 1 5/16 gallon

Thus , Karen and Robin have 1 5/16 gallon ice tea together.
