Answer:
22
Step-by-step explanation:
(5x-7 )+(4x-11)=180 ( it equals 180 because those two angles equal 180)
Then add the similar things together
5x+4x=9x
-7-11= -18
9x-18=180, add 18 on both sides to get 9x alone
9x=180, then divide 180 by 9 to get x alone
x=22
Answer:
x = ± 
Step-by-step explanation:
Given
y = x² + 7 ( subtract 7 from both sides )
y - 7 = x² ( take the square root of both sides, thus
x = ± 
To divide fractions be multiply by the resiprical
4 6 24
--- x ---- = ------
1 7 7
then simplify into a mixed number
3 3/7
