Answer:
x = 24
Step-by-step explanation:
In order to solve for x, you need to isolate it on one side of the equal sign. So in this case you need to multiply both sides by 4, in order to cancel the dividing factor 4 that appears in the denominator :
You will need 90 cookies. If you do 30/15, you get 2. Then you do 45x2 and get 90!
Ur 2 angles, when added, form a line....so they are a linear pair that equals 180
5k - 3 + 9 + k = 180
6k + 6 = 180
6k = 180 - 6
6k = 174
k = 174/6
k = 29
Answer:
Angle 4 = 135, angle 5 = 45
Step-by-step explanation:
Consecutive interior angles are supplementary, therefore angle 5 + angle 8 = 180 degrees. Since the complement of 5 is the supplement of 4, we can write the system of equations.
180 - x = 90 - y or -x + y - 90 - 180 or -x + y = -90 or x - y = 90
x + y = 180
x - y = 90
Where angle 4 is x and angle 5 is y.
y = 180 - x
x - (180 - x) = 90
x - 180 + x =90
x + x = 270
2x = 270
x = 135
By plugging that in to an equation we can solve for y.
y = 45
