If one is at a speed of 35 mph and the other 60, sum the speeds to work with just one number:
35 + 60 = 95mph
The formula for time is:
Time = Distance / Speed
Time = 855 / 95
Time = 9h (D.)
Hope it helped,
Happy homework/ study/ exam!
Break up chain with AND statement:
(2/3)t - 1 < t + 7 AND <span>t + 7 ≤ -2t + 15
left side, we solve for t
</span>
<span>(2/3)t - 1 < t + 7
(2/3)t - t < 7 + 1
(-1/3)t < 8
t > -24
right side, we solve for t</span>
<span>t + 7 ≤ -2t + 15
t + 2t </span><span>≤ 15 - 7
3t </span><span>≤ 8
t </span><span>≤ 8/3
So our answer would be </span>
t > -24 AND t <span>≤ 8/3
as an interval, this is
</span>-24 < t <span>≤ 8/3
or in interval notation
(-24, 8/3]</span>
Total cost = $13.05 + 10.26
= $23.31
Indivdual pay = $23.31 / 3
= $7.77 each
Answer:
12
Step-by-step explanation:
1/5 of 30 is 30/5 = 6
1/2 of (30 -6) = 12 . . . half of those remaining after mint icing
The other half of those remaining is also 12 cupcakes. So, 12 cupcakes will get vanilla icing.
5p-30 is the simplification to this rather simple equation.
