Since the slope stays the same as it's parallel, we have y=(3/4)x+b. Plugging (2,-1) in, we get -1=3*2/4+b=6/4+b=1.5+b. Subtracting 1.5 from both sides, we get -2.5=b and our equation being y=(3/4)x-2.5 (since in y=mx+b, y and x remain as variables)
Answer:
a.7/4x
b.2/3c
Step-by-step explanation:
Hello there!
The answer would be C since we are looking to find how far she ran based on the amount of miles that has passed.
As stated above, 6 minutes. However to find out how far she runs we have to change the speed to miles per minute.
6 minutes per mile is equal to 1/6 of a mile per minute
Formula for Distance is speed x time
The distance is d, the time is t and the speed is 1/6.
Plug it in:
d = 1/6t
Lastly, multiply by 6 on both sides.
d x 6 = 1/6t x 6
1/6 x 6 = 1t
6d = 1t
Answer: t= 6d
If George completed 3/5 of work in 9 days, it means that he needs 3 days to finish 1/5th of the work.
The remaining part is 2/5 because 1-3/5=2/5. 2/5 is also 6/15
From this, how much did George do? in the first 3 days he did 1/5th and then one more day was left, during which he did 1/5/3=1/15th.
So he did in total 1/15+1/5=1/15+3/15=4/15.
this means that Paul did the rest of 6/15, so Paul did 6/15-4/15=2/15.
So we know that he does 2/15 in 4 days, which means that every two days he can do 1/15 of the work
so he would need 15 times 2 days to finish the work - 30 days!
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)
