They sold 17 rolls. Because:
$4×45= 180
$265-180= 85
85÷5= 17
Based on the definition of supplementary angles, the measure of both angles are: 80° and 100°.
<h3>What are Supplementary Angles?</h3>
The sum of angles that are supplementary to each other equals 180 degrees.
Let the measure of the supplementary angle be x.
The other angle will be: x + 20.
(x + 20) + x = 180
x + 20 + x = 180
2x + 20 = 180
2x = 180 - 20
2x = 160
x = 160/2
x = 80°
The other angle will be x + 20 = 80 + 20 = 100°.
The measure of the angles are: 80° and 100°.

Every 5 red cars there are 3 Blue cars,
So if there are 40 red cars,
there are going to be 24 Blue cars
40 divided by 5 which is 8
Multiply 3 × 8 which is ( 24 blue cars )
Answer:
Step-by-step explanation:
4x-4y -2z = 6 ( first equation x2)
4x+ 5y-2z =-3 ( If you substract these two)
-9y= 9 so y= -1
2x-z =1 (multiple by 3 ) then 6x-3z=3
3x-3z= -3
3x=6 x=2 and z=3
The answer is x=2, y=-1 and z= 3
