Answer:
4x-20 is the same as x+x+x+x-20
The answer is C because when you divide it out you get 6
Answer:
(1,0)
Step-by-step explanation:
Absolute value is represented by using these bars → ║.
║= number of units from 0.
This equation says that whatever number is in the absolute value bars , x , is greater than y.
360 is one of many numbers divisible by this number set.
Answer:
The measures of the angles are 150° and 30°.
Step-by-step explanation:
Let x and y represent the measures of the angles, with x representing the larger angle.
x + y = 180 . . . . . . the two angles are supplementary
x = 90 + 2y . . . . . one is 90° more than twice the other
___
Substituting the expression given by the second equation into the first, we have ...
(90 +2y) +y = 180
3y = 90 . . . . . . . . . . collect terms, subtract 90
y = 30 . . . . . . . . . . . divide by the coefficient of y
x = 180 -y = 150
The measures of the angles are 150° and 30°.
