Answer:
x = 5
Step-by-step explanation:
The difference between consecutive terms will be equal , then
a₂ - a₁ = a₃ - a₂ , that is
x + 9 - (3x - 2) = 2x + 5 - (x + 9) ← distribute parenthesis on both sides
x + 9 - 3x + 2 = 2x + 5 - x - 9 , simplify both sides
- 2x + 11 = x - 4 ( subtract x from both sides )
- 3x + 11 = - 4 ( subtract 11 from both sides )
- 3x = - 15 ( divide both sides by - 3 )
x = 5
Answer:
1. Add 17 to both sides
2. Divide both sides by 4
Step-by-step explanation:
We have been given the equation
In order to solve the equation, we apply the below mentioned steps:-
Step 1:
Since, 17 is in subtraction with 4x hence, to get rid of this we add 17 to both sides of the equation.
Step 2:
Now, 4 is in multiplication with x, hence to get rid of 4, we do the reverse operation of multiplication which is division.
Hence, divide both sides by 4
Hence, the correct option should be
1. Add 17 to both sides
2. Divide both sides by 4
Answer:
11.x=100
12.x=118
Step-by-step explanation:
using the interior angles theorem the space below x is 80 degrees
the space below 80 is x
Every paralellogram equals 360 degrees
add all angles and subtract from 360 to find x
80+80+x+x=160+x2
x2=200
x=100
Use the same thing for 12
62+62+X+X=360
124+2X=360
2X=236
x=118
