answer: 4s+4
(s+12)+(3s-8) distrubute --> s+12+3s-8
comibine like terms 4s+4
hopfully this helped :)
10/23=15/m
(15x23)/10
343/10
34.3
so....
10 laps in 23 minutes
=
15 laps in 34.3 minutes
Answer:
y=-9
Step-by-step explanation:
slope intercept form: y=mx+b, m being the slope
y=6 times -3
since there isn't a y intercept, you can't really put it in standard form unless I missed a step.
y= -9
Answer:
first, u need to know the formula for compound interest, which is:
where A is the final amount
P- initial amount
r- percent compounded(interest)
and
n- number of years
so
we have
3.8/100 = 0.038
1+0.038 =1.038
1.038^4 = 1.160885573136
475 * 1.160885573136 = 551.4206472396
approximately $551.42
Answer:
There are 6 dimes and 9 quarters.
Step-by-step explanation:
Represent the number of dimes and the number of quarters by d and q.
Then d + q = 15, or q = 15 - d.
Also, ($0.25)q + ($0.10)d = $2.85, or 5q + 2d = 57.
Substituding 15 - d for q, we get 5(15 - d) + 2d = 57, or
75 - 5d + 2d = 57, or
75 - 3d = 57, or
3d = 18. Thus, there are 6 dimes. Since q = 15 - d, q = 15 - 6 = 9.
There are 6 dimes and 9 quarters.
