<u>Answer:</u>
Subtract 43 from 20 raised to the 7th power; then multiply by 3. The answer is: <u>3,839,999,871</u>
Step-by-step explanation:
"Subtract" means to take away a number from another.
" 20 raised to the 7th power" is the same thing as 20 exponent 7:
SO, you want to take away 43 from and then multiply the answer by 3:
( - 43) × 3
1,280,000,000
(1,280,000,000 - 43) × 3
1,280,000,000 - 43 = 1,279,999,957
1,279,999,957 × 3
1,279,999,957 × 3 = <u>3,839,999,871</u>
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
y =
Step-by-step explanation:
Given
y = 3xy - 1
Collect terms in y on the left side by subtracting 3xy from both sides
y - 3xy = - 1 ← factor out y on the left side
y(1 - 3x) = - 1 ( divide both sides by 1 - 3x
y = ← multiply numerator/denominator by - 1
y =
