Answer: A
Step-by-step explanation: because I had that same test last year
Supplementary angles always equal 180. Then you just solve from there.
7x+5x+24=180
12x+24=180
-24 -24
12x=156
/12 /12
X=12
Answer:
it's b
Step-by-step explanation:
the denimonater is the root of the radical and the power
Hope this helps :)
15x+3x+10 = 38x-20x+10
18x+10 = 18x+10
18x-18x = 10-10
0 = 0
The equation is true.
7 14/18 since you can reduce this to 7 7/9:)
