Answer
x=33
Step-by-step explanation:
since they're both on the same line we must equal them to 180.
18 + x + 4x -3 = 180 (Now you simplify terms)
5x + 15 = 180 (Subtract the 15 from both sides)
5x = 165 (divide by 5 to isolate the variable)
x = 33 (Hope I was able to help :) )
The 1, 2, 3 I’m not sure bout the 4th one
So using a calculator this question is really easy 125,000x 1.35 ^10 =.
