You add 13 and 8 it gets 21 so for X its 13

X = 13.

Because you want x by itself, to need to remove the +8. So, you must do the opposite to BOTH sides. The opposite of +8 is -8, and 21-8=13. Therefore​, x=13.

Find x and round to the nearest tenth:)
Thepotemich [5.8K]

Answer:

x = 31.8°

Step-by-step explanation:

Applying the Law of Sines, we have:

\frac{sin(x)}{12} = \frac{sin(75)}{22}

Multiply both sides by 12

\frac{sin(x)}{12} \times 12 = \frac{sin(75)}{22} \times 12

sin(x) = \frac{sin(75) \times 12}{22}

sin(x) = 0.5269

x = sin^{-1}(0.5269)

x = 31.8° (nearest tenth)

In 3 1/2 lb is the same as 7 of 1/2 lb so
2.80/7= $0.4 per 1/2 lb
One pound costs 0.4•2= $0.8
