First your going to distribute the 3
3(-3x+15)
-9x+45
27=6x-9x+15
27=-3x+15
Then you’ll minus 15 from 27
27-15=12
12=3x
X=4
Answer: 180 = 30 + (x + 60)
Step-by-step explanation: Supplementary means that the angles add together to 180 degrees. This equations shows that angle A (30 degrees) plus angle B (x + 60) equal 180. If you solve the equation you will find that angle B is equal to 150 degrees, and that x = 90.
Cos ( theta ) = cos 7π/6 = -√3/2
sin ( Theta ) = sin 7π/6 = -1/2
Coordinates of the terminal points are: ( -√3/2, -1/2 )
Answer:
11/4 = 5/4
If you need 5/4 cups of sugar to make 20 cookies or in other words,
For 20 cookies you need 5/4 cups of sugar then
for 14 cookies you will need: 14 * (5/4)/20 = 7/8 cups of cookies
if you like a very sweet cookies then you can add a bit more sugar to make it 1 full cup of suger
