Step-by-step explanation:
Answer:
n = 6
Step-by-step explanation:
Step 1: Write equation
-15 + n = -9
Step 2: Add 15 to both sides
n = 6
Step 3: Check
<em>Plug in n to verify it's a solution.</em>
-15 + 6 = -9
-9 = -9
Answer:
x=−11
Step-by-step explanation:
7+5(x−3)=7(x+2)
Step 1: Simplify both sides of the equation.
7+5(x−3)=7(x+2)
7+(5)(x)+(5)(−3)=(7)(x)+(7)(2)(Distribute)
7+5x+−15=7x+14
(5x)+(7+−15)=7x+14(Combine Like Terms)
5x+−8=7x+14
5x−8=7x+14
Step 2: Subtract 7x from both sides.
5x−8−7x=7x+14−7x
−2x−8=14
Step 3: Add 8 to both sides.
−2x−8+8=14+8
−2x=22
Step 4: Divide both sides by -2.
−2x
−2
=
22
−2
x=−11
The correct answer is A. 109 degrees.
Explanation:
Because the angles are supplementary, their sum is 180 degrees.
We know that one of them is 71 degrees, so we substract that from 180, therefore the other angle is 109 degrees.
Step-by-step explanation:
Use midpoint formula: Xa+Xb/2 ; Ya +Yb/2
- MAB = Xa +Xb/2 ; Ya +Yb/2
- MAB=(-7+6)/2 ; (-9+3)/2
- MAB= -1/2 ; -6/2
Therefore midpoint is -½ ; -3
