18 = .75x
/.75 /.75 (divide both sides by .75 to isolate x)

Hello. 10x-3-2x=4 ; 10x-2x=4+3 ; 8x=7 ; x=7/8. I hope to have helped you
PEMDAS Solve the parentheses first so 9+4=13. Then do the division so 6/6=1. Now the equation is 37- 13+ 1. Then work left to right. 37-13= 24 then 24+1=25.
I would think 3? it should be 3 because 32*2=64 which isn’t everyone 32*3 is 96
79+12=91
Answer: B, x=20; angle measure is 30°.
Step-by-step explanation:
Opposite angles are always the same.
You can see that 30° and 3x are opposite angles therefore 3x=30°.
In algebra, when a letter and a number are next to each other, it means times.
So, 3x=30° means 3 times something equals 30.
And we know that 3×10=30 so, x=10.
Hope this helps :)
