2.

1 day = 24h

1h = 60min

We have 4h 20min

$4h + 20min = 4h+\dfrac{20}{60}h=4h+\dfrac{1}{3}h=4\dfrac{1}{3}h=\dfrac{13}{3}h$

$\dfrac{\frac{13}{3}}{24}=\dfrac{13}{3}\cdot\dfrac{1}{24}\\\\\huge\boxed{(D)\ \dfrac{13}{72}}$

3.

6:51PM + 9min → 7:00PM

7:00PM + 27min → 7:27PM

9min + 27min = 36min

$36min=\dfrac{36}{60}h=\dfrac{3}{5}h$

$\huge\boxed{(C)\ \dfrac{3}{5}}$

F=9/5C + 32 find C (9 fifths is a fraction)

REY [17]

Start with the given equation. Subtract 32 from both sides. Multiply both sides by 5.
Divide both sides by

Can some one help me asap

It'd be easier to do #18 if y ou were to break it up:

14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2

14(1+14)
= ---------------- = 7(15) = 105
2

The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.

The final sum is 210 + 14 = 224 (answer)
