I don’t know I’m just typing so I can get a Anwser for mine
If you take the total height and divide it by the number of cases it, it will then give you the heigh of just one case.
90 divided by 6=15
It’s 15 millimeters per DVD case. Then you take 15 and multiply it by 13 to get the total height of the stack of 13 cases.
Hope this helps!
Answer:
The Inequality describing the situation is
.
Step-by-step explanation:
Let the number of laps he runs be 
Let the number of laps he swims be 
Now Given:
Time required to run each lap = 3 min
Time required to swim each lap = 2 min
Total minutes he need to exercise more than 45
we need to write the Inequality representing the same.
Solution:
Now we can say that;
Time required to run each lap multiplied by the number of laps he runs plus Time required to swim each lap multiplied by the number of laps he swims should be greater than Total minutes he need to exercise.
framing in equation form we get;

Hence The Inequality describing the situation is
.

=

Cross multiply
12x=900 Divide both sides by 12.
x=75 hammers to begin with.
Answer:
y=2x+15
Step-by-step explanation:
Slope (m) = 20/10 = 2
y-intercept (b) = 15
