a)

  F  = \frac{5}{9}(K - 273.15) + 32

<u>- 32</u>    <u>                      - 32</u>

F - 32 = \frac{5}{9}(K - 273.15)

\frac{9}{5}(F - 32) = \frac{9}{5}[\frac{5}{9}(K - 273.15)]

\frac{9}{5}(F - 32) = K - 273.15

\frac{9}{5}F - \frac{9(-32)}{5} = K - 273.15

\frac{9}{5}F - 57.6 = K - 273.15

<u>     + 273.15</u>    <u>   + 273.15  </u>

\frac{9}{5}F - 215.55 = K

b)

\frac{9}{5}(180) - 215.55 = K

324 - 215.55 = K

108.45 = K

Emerson is making a punch that contains 60% grape juice and the rest lemon-lime soda. The punch has 2 liters of lemon-lime soda.
IrinaK [193]
A punch contains 60% of grape juice and the rest is lemon - lime soda ( 2 liters).
Part A:
An equation is:
0.6 x + 2 = x,
where x stays for the liters of punch.
Part B:
x - 0.6 x = 2
0.4 x = 2
x = 2 : 0.4
x = 5 liters
Grape juice = 5 - 2 = 3 liters.
Answer: There are 3 liters of grape juice in the punch.

All you have to do is multiply the l * w = Area

When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.

So the dimensions of the ceiling are l = 20 ft; w = 9 ft

If you buy six pens and one mechanical pencil, you'll get only $1 change from your $10 bill. but if you buy four pens and two me
xxTIMURxx [149]

Let p be the prize of a pen and m the prize of a mechanical pencils. If you buy six pens and one mechanical pencil, you spend 6p+m. We know that this equals 9, because you get 1$ change from a 10$ bill.

Similarly, if you buy four pens and two mechanical pencils, you spend 4p+2m, which is 8$, because now you get a $2 change. Put these equation together in a system:

\begin{cases} 6p+m=9\\4p+2m=8\end{cases}

Now, if you multiply the first equation by 2, the system becomes

\begin{cases} 12p+2m=18\\4p+2m=8\end{cases}

Subtract the second equation from the first:

12p+2m - (4p+2m) = 18-8 \iff 8p = 10 \iff p = \dfrac{10}{8} = 1.25

Plug this value into the first equation to get

6p+m=9 \iff 6\cdot 1.25 +m = 9 \iff 7.5 +m=9 \iff m = 9-7.5 = 1.5
