Answer:
x = 200
Step-by-step explanation:
Multiply by 4:
x + 120 + 2x = 720
3x = 600 . . . . . . collect terms, subtract 120
x = 200 . . . . . . . divide by 3
_____
<em>Check</em>
(200/4 +30) +(200/2) = 180
(50 +30) + 100 = 180
80 + 100 = 180 . . . . . true
_____ _____
<em>Alternate solution</em>
If you like, you can simply work with the equation given.
(3/4)x + 30 = 180 . . . . collect terms
(3/4)x = 150 . . . . . . . . . subtract 30
x = 200 . . . . . . . . . . . . multiply by 4/3
Answer:
A. 10,000
B. 1,000,000
C. 10,000,000,000
D. 1,000,000,000,000
Step-by-step explanation:
10,000/ 10∧4 = 1
1,000,000/ 10∧6 = 1
10,000,000,000/ 10∧10 = 1
1,000,000,000,000/ 10∧12 = 1
Hope this helps! Good luck!
