Answer:
60 mph?
Step-by-step explanation:
If she drives 320 miles in 5 hours, her average speed would be 64 mph, but 60 is the closest so I would go with that I guess. I'm pretty sure these are all wrong options though
Y=mx+b
ok, so notice that b is constant, doesn't change, when x=0, then y=b
that is the starting value
it is stated that he has 41 at the begining so
y=mx+41
alright
so we are also given
when x=5, y=66
so find m
66=5m+41
miinus 41 from both sides
25=5m
divide both sides by 5
5=m
the equation is
y=5x+41
Answer: I believe 138

Answer:
<em>Multiply by 100</em>
Step-by-step explanation:
The equation is given as:
-m + 0.02 + 2.1m = -1.45 - 4.81m
To eliminate the decimals from all the terms, we must multiply by a number that make all the coefficients integers.
The decimal coefficients and independent terms are
0.02, 2.1, 1.45, 4.81
Note the maximum number of decimals found in all of them is 2. Thus, multiplying by 100 all the decimals will vanish as follows:
100(-m + 0.02 + 2.1m) = 100(-1.45 - 4.81m)
-100m + 2 + 210m = -145 - 481m
Now all terms have integer coefficients as required.
