(2x+3)+(x-6)= 180 [straight angle]
2x+x+3-6=180
3x=183
x=61
(All measure in degree)
Hope this can help.
Answer:
y=mx+b
Step-by-step explanation:
Y is just y
m is the slope
x is the x point
b is the y intercept
<h3>Solution and Explanation:</h3>
If
and
are directly proportional, then they must have a common scalar.
To find
we must first find its scalar. If we let
be the scalar we can form the equation,
.
We are given the information that if
then
. We can use that in finding the scalar.

Now we can solve for
when
knowing that our scalar is
.

<h3>Answer:</h3>
when 
Sarah,
Let x = cost of notebook
let y = cost of thumbdrive
For Troy 5x + 5y = 75
For Lisa 2x + 6y = 78
Troy's equation let's divide it by 5 and get
x+ y = 15 multiply by -2
-2x -2y = -30
2x + 6y = 78 Add equations
4y = 48
Solve for y. Then plug it in one of the original equations and solve for x. Check by plugging into the other original equations
