Answer:
9 weeks
Step-by-Step Instructions:
Step 1: State what is know
Bart deposits 10 dollars every week
Bart has 90 dollars in his account
Step 2: Find a way to solve for how many weeks Bart ha been depositing money
Total money in account / 10 dollars deposit per week = weeks he has been depositing
Step 3: Substitute in values and solve
90/ 10 = 9
Step 4: State your findings
Therefore Bart has been depositing money for 9 weeks
From -5 to 0 is 5 degrees and from 0 to 5 is 5 degrees.
5 + 5 = 10
It is 10 degrees warmer outside.
Answer:
9 days
Step-by-step explanation:
First, write the equation for Daniel's situation:
D = 17t + 49
Then, write the equation for Audrey's situation:
A = 20t + 22
Then, set these equations equal to each other and solve for t to find when they will be on the same page:
17t + 49 = 20t + 22
Solve for t:
17t + 49 = 20t + 22
49 = 3t + 22
27 = 3t
9 = t
So, they will be on the same page 9 days into the month.
Answer:
x = 6
Step-by-step explanation:
-3.5x + 8.5x - 4 = 26
-3.5 + 8.5x = 26 + 4
5.0x = 30
x = 30/5
x = 6
