Because a triangles angles add up to 180 degrees, we can say that 

x+4+3x+9+31=180 degrees.

The question is now a simple algebraic expression.

4x+44=180
Subtract 44 on both sides

4x=136
Divide by 4 on both sides

x= 34

m∠S<span>= x+4, (34)+4, 38
</span>m∠S=38 degrees

m∠T= 3x+9, 3(34)+9, 102+9, 111
m∠T=111 degrees

I hope this helps and please mark brainiest answer :D

11. Solve for x: 2x - 3 = -7 + x
Sophie [7]

Answer:

x = -4

Step-by-step explanation:

Step 1: Write equation

2x - 3 = -7 + x

Step 2: Solve for <em>x</em>

  1. Subtract x on both sides: x - 3 = -7
  2. Add 3 to both sides: x = -4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

2(-4) - 3 = -7 + (-4)

-8 - 3 = -7 - 4

-11 = -11

PLEASE HELP ME WITH THIS<br><br>​
Vladimir [108]

Answer:

A. (0, 60)

B. 15x

Step-by-step explanation:

The initial value is the same as the y-intercept, which is 60 or (0, 60).

The rate of change would be the same as the slope. To find the slope, you do rise/run. You move 15 units up, and 1 to the right. That would be 15x.

Hope this helps!
