Answer:
400
Step-by-step explanation:
Car A costs 80d + 0.25m, where d is days and m is miles. Car B costs 100d + 0.10m. If you plug in 3 for d and make the equations equal, you get 240 + 0.25m = 300 + 0.10m. Combining like terms gives you 0.15m = 60, and dividing gives you m = 400.
To find out how many 3 course meals there are you will multiply all three numbers together. The reason for this is that you can group each item with each of the other options. This is a triple grouping.
4 x 4 x 5 = 80
There are 80 possible combinations.
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

Parallel lines have the same slope. Therefore if given line is

then the slope of our line is
.
We have the equation:

The line passes through (-1, -7). Put the coordinsted pf the point to the equation:

<em>add 2 to both sides</em>

Finally:

Answer:
6 1/4
Step-by-step explanation:
Total length of the ribbon= 15 3/4 m= 63/4 m
One piece= 9 1/2 m= 19/2 m
Other piece length =X
X= 63/4-19/2
=63/4-38/4
=25/4
=6 1/4
