Answer:
3(t-y)
Step-by-step explanation:
difference means subtractions
3*(t-y)
Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
X equal what umber,and y equal what number?
12 + 36 = 48
your answer is 48 inch
hope this helps
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°.
