Answer: x = -4, x = 5
Step-by-step explanation:
You can use the substitution method for this problem.
y = 
+ 2x, but y also = 3x +20.
Because of this, you can determine that +2x = 3x + 20 because they are both equal to the same thing, y.
Solve the quadratic equation you got from substitution:
+ 2x = 3x + 20
-x = 20
-x -20 = 0
You can factor this equation:
(x+4)(x-5) = 0
x = -4, x = 5
Answer:
Number 1 is 55
Number 2 is 60 :)
Step-by-step explanation:
(115 - 5)/2
110/2
55
Number 1 is 55
Number 2 is 60 :)
60 + 55
110 + 5
115 :)

this an example not the answer i don't know the answer
E is between D and F.
Given: E is between D and F
Prove: DE = DF − EF.
Statements Reasons
1. E is between D and F Given
2. D, E, and F are collinear points, and E is on ¯DF Definition of between
3. DE + EF = DF Segment Addition Postulate
4. DE = DF − EF Subtraction property of equality
2. If →BD divides ∠ABC into two angles, ∠ABD and ∠DBC, then m∠ABC = m∠ABC - m∠DBC.

Hello!
From the exterior angle theorem, we know that an exterior angle is equal to remote interior angles added up. The exterior angle in this problem is 140 degrees so we also know that the remote interior angles are congruent. We can denote the interior angles as x and both combined is 2x.
Then we can create the equation:
2x = 140
x = 70
The two remote interior angles are 70 degrees.
The last interior angle is 180 - 140 = 40 degrees
