Aimee's karate class starts at 4:00 pm.
If Aimee's karate class lasts for 1 hour and 15 minutes and ends at 5:00 pm, we can determine the start time by subtracting 1 hour and 15 minutes from 5:00 pm.
To subtract the time, we convert 1 hour and 15 minutes to minutes:
1 hour = 60 minutes
1 hour and 15 minutes = 60 minutes + 15 minutes = 75 minutes
Now, we subtract 75 minutes from 5:00 pm:
5:00 pm - 75 minutes = 4:00 pm
Therefore, Aimee's karate class starts at 4:00 pm.

___ hours
Answer:
80+2h=72+4h
4hours
Step-by-step explanation:
80+2h=72+4h
80-72=4h-2h
8=2h
h=8/2
h=4
Answer:
It took 4 hours for the two cities to reach the same temp.
Step-by-step explanation:
Part 1
First, you will write an expression for each city.
Austin starts at 80°F and rises 2°F per hour. 80 is our starting point. 2 is how much is added each hour. The per hour means we need a variable.
Little Rock starts at 72°F and rises 4° per hour. 72 is our starting point. 4 is how much is added per hour. The per hour means we need a variable.
Second, you want to know when the cities are equal, so you set these expressions equal to each other.
Part 2
This is an equation with variables on both sides. You will need to follow a few steps to solve these problems.
Step 1: look for grouping symbols. This problem does not have any visible or invisible grouping symbols.
Step 2: Look at the left side. Are there any like terms? This problem does not have any like terms on the left side. Look at the right side. Are there any like terms? This problem does not have any like terms on the right side.
Step 3: Are there variables on the left and right side of the equal sign? (Look to the left of the equal sign; you will see 2h. The h is a variable on the left side. Look to the right of the equal sign; you will see 4h. The h is a variable on the right side.)
Step 4: Are there constants on the left and right sides of the equal sign?
Step 5: Does the variable have a coefficient other than 1? (Is there a number written with the variable? Is the variable not 1?)
You have now solved the equation for the variable. Remember h was defined in the problem as "the number of hours it took for the cities to reach the same temperature." This means that it took 4 hours for the cities to reach the same temperature. You can check this with a simple check
You substitute the 4 in the original expressions. If you did the work correctly, you will get the same answer for both equations.
Since both expressions produced the same answer when 4 was substituted the answer is correct.
4/X=12/7.5
Answer:
x = 2.5
Step-by-step explanation:
Given
= = 1.6
Multiply both sides by x
4 = 1.6x ( divide both sides by 1.6 ), hence
x = 2.5
Answer:
1.73 hours
Step-by-step explanation:
This can be solved with proportions.
Cross multiply and you get:
Divide by 2.58 gallons and you get:
And to find out the number of hours that is, divide by 60 and you get 1.73 hours.
