Not completely sure on the symbols, but I think it is 5 x ( 22 - 9 x 2 ) - 2 ( 3 x 2 x 4 ) x 7 = 136. It doesn't really match the answers, so my advice is that you use a calculator for this one, or as the person/teacher who gave you the problem how to solve it.
Answer:
8 dollars
Step-by-step explanation:
We can write a ratio to solve
15 stickers 12 stickers
------------------ = ----------------------
10 dollars x dollars
Using cross products
15 *x = 12 * 10
15x = 120
Divide each side by 15
15x/15 = 120/15
x =8
8 dollars
To find the difference, subtract Thea's earnings from Hadley's earnings.

Answer:
x=6.09cm
Step-by-step explanation:
Working out AB:
7.5²+4.9²
= √80.26
AB= 8.96cm
To work out x:
AB is the opposite, where BC is the adjacent. This means that we have to use TOA.
x=8.96/Tan(55.8)
x= 6.09cm
