Answer:
B. 12 days
Step-by-step explanation:
This can be set up as an equation:
64x = 768, where x represents the days it will take to achieve 768 doughnuts.
Divide both sides by 64.
x = 12.
It will take 12 days to make an additional 768 doughnuts.
Answer:
5
Step-by-step explanation:
34.05
34.05 x 10 to the power of six = 3405000
decimal point needs to move 5 places to go after the last zero
From step 1 to step 2 they distributed the 2 (multiplied the inner numbers of the parentheses)
From step 2 to step 3 they added 6x to both sides,canceling out the -6x on the left side and adding 6x with the 5x
From step 3 to step 4 they subtracted 2 from both sides, canceling it out on the right side and subtracting 2 from 8 to get 6
From step 4 to step 5 they try and get x alone by dividing both sides by 11, canceling out the 11 on the right side and leaving a fraction the left
Leaving you with your answer of what x equals in the final step
Hope this helps!!
