3(18 - x/3 = -7)
54-x = -21
-x = -75
x = 75
Answer:
-7/45
Step-by-step explanation:
First, find the lowest common denominator for 9 and 15. It's 45. Make both fractions over 45 by multiplying the top and bottom by the same number.
Since 15*3=45, multiply the top by 3 also. Since 9*5=45, multiply the top by 5 also.

Answer:
The answer will be 38° + 32° = 70°
<em>Please mark me as the brainliest</em>
suppose 4:4:7 be 4x, 4x, 7x
or, 15x = 180°
or, X = 180/15
or, X = 12
therefore,
4x = 4x12= 48
4x= 4x12= 48
7x= 7x12= 84
so if you plus all of them you get 180
