Answer:
C.
Step-by-step explanation:
When two lines are parallel, their slopes are the same.
Since the slope of line <em>l </em>is 2/7, the slope of its parallel line <em>m</em> must also be 2/7.
The answer is C.
Answer:
You don't really need to do it, but it helps you keep things more organized and easier to follow. Imagine if you're doing some multi-variable equation,
2a + 5b + 4d + 3c + b + a + 2d
that looks like a mess, it'll be easier to look at if you put all the similar variables next to each others like this:
a + 2a + b + 5b + 3c + 2d + 4d
(a + 2a) + (b + 5b) + 3c + (2d + 4d)
now you can add them up much easier.
Chad makes $10 per yard, and he makes 3 yards
3 x 10 = 30
Chad makes $5 per hour, and he works 8 hours
5 x 8 = 40
30 + 40 = 70
Chad makes $70 in all
hope this helps
