Answer:
C . 4
Step-by-step explanation:
step 1 : -3 multiply with inside of the ( 7x-5 )
= -21x + 15
step 2 : then it will be 21x + 15 = 87 + 3x
step 3 : switch between the odds into like this
21x - 3x = 87 - 15
step 4 : subtract it all
18x = 72
step 5 : bring 18 to the other side
x = 72/18
step 6 : to find the ans of x is just calculate them
x = 72 ÷ 18
= 4
Or you can do like these ⬇️
-3 ( 7x - 15 ) = 87 + 3x
21x + 15 = 87 + 3x
21x - 3x = 87 - 15
18x = 72
x = 72/18 or 72÷18
x = 4
Answer:
21 1/3
Step-by-step explanation:
we turn the fraction into an improper fraction...
8/3 x 8/3 = (8*8)/3= 64/3 = 21 1/3
The formula to use is
n = 360/E
where
n = number of sides
E = measure of exterior angle
In our case, E = 15 so
n = 360/E
n = 360/15
n = 24
This regular polygon has 24 sides
First, move x to one side of the equation, opposite of y, so you can get y= something
Then your equation becomes -y=-x+1
You can't have a negative y so divide both equations by one.
Your new equation is y=x-1
To graph, you start at the point (0,-1) then go to the right one and up one
