Answer:
1) MArta's rate= 1/10 = 0.1 miles per minute
2) Ira was the fastest on the last ride
Step-by-step explanation:
Marta 's rate in miles per minute= distance/ time= 8/80= 1/10= 0.1 miles per minute
Loribeths 's rate in miles per minute= distance/ time= 6/42= 1/7 = 0.142 miles per minute
Ira's s rate in miles per minute= distance/ time= 15/75= 1/5= 0.2 miles per minute
Comparing the three results Ira is the fastest
Yes the answer is 14 good job
Answer:
y=
x=
Step-by-step explanation:
7x+4+12x+24=180
19x+28=180
19x=180-28
19x=152°
19x/19=152/19
x=8
y=7x+4
y=7*8+4
y=60°
Answer:
The answer is no because .
Step-by-step explanation:
If is a factor of , then .
Let's check.
Since , then is not a factor of .
======================================================
So anyways more on how this works:
If where is the remainder and is the quotient of the division, then multiplying both sides by gives .
We see that is a factor if the remainder is 0. (Just like we know 2 is a factor of 6 because when we divide 6 by 2 we get a remainder of 0.)
Anyways if we evaluate for we get:
So evaluating for will tell us the remainder of the quotient without actually performing division.
The remainder will tell us if is a factor of
If the remainder is 0, then the answer is yes.
If the remainder is not 0, then the answer is no.
(The question to be answer "Is this a factor of this?")
