Vertical Angles: Theorem and Proof
Theorem: In a pair of intersecting lines the vertically opposite angles are equal. It can be seen that ray \overline{OA} stands on the line \overleftrightarrow{CD} and according to Linear Pair Axiom, if a ray stands on a line, then the adjacent angles form a linear pair of angles.

0.7(3s+4)−1.1s=7.9 I need a answer
Mamont248 [21]

First, expand the bracket

2.1s + 2.8 - 1.1s = 7.9

Next, collect like terms

s + 2.8 = 7.9

Lastly subtract 2.8 from 7.9 to get your answer.

s = 5.1

(Hope this helps! ^^)

10+4x = 5(x−6)+ 33<br> solve for x
lions [1.4K]

Answer:

X=7

Step-by-step explanation:

10+4x=5(x-6)+33

1. Distribute the 5 to both the x and the 6

10+4x=5x-30+33

2. Subtract 4x from 5x ( should be left with 1x but just write x)

10=x-30+33

3. add 30 to both sides (whole number on the left, x on the right)

40=x+33

4. Subtract 33 on both sides

7=x (flip it around)

x=7
