One angle is 10 less than four times another angle. If the two angles are supplementary what is the measure of each angle? Find the correct equation one can use to solve this problem.Question 6 options:

a)

(x−10)+x=180

b)

(4x−10)+x=180

c)

4x+10=180

d)

x+(4x−10)=90

Answers

Answer 1

Answer: Supplementary angles must add up to 180. Let x equal "another angle." "One angle" is ten less than four times x. This would look like: 4x-10. 4x-10 and x must add up to 180: (4x-10) + x =180. This is choice B.

80% of a number is 96. What is 25% of that same number?

A.
20

B.
30

C.
40

D.
120

Answers

$(80)/(100)*x=96$ ⇒ $(80/20)/(100/20) *x=96$

$(4)/(5)*x=96$ ⇒ $x= (96*5)/(4)=24*5$

$\boxed {x=120}$

$(25)/(100)*x= (25/25)/(100/25)*120 = (120)/(4) = \boxed {30}$

The answer is B.

let the number be x
80%*x=96
x=96/80%
x=120
then 25% of 120 is your answer to find this half 120 twice
half 120=60
half 60=30

Therefore 30 is the answer which is B
