Answer:

a= 1/2p-b

Step-by-step explanation:

p=2a+b

divide by 2 on both sides

1/2 p = a+b

subtract b from both sides

1/2 p - b = a

flip equation (not needed, just personal preference)

a= 1/2p-b

(Sorry if I didn't understand well enough and got it wrong)

Answer: 5.196152423

Step-by-step explanation: Logically considering it's a Rhombus all the sides are equal to each other. So you just need to find the area. In this case you find the area by multiplying the sin of the given angle by the square root of the given side. So, 6²×sin (60)=6²×√3/2=31.17691454. After finding the area you then have to divide the area by it's base to find the height. So, 31.17691454 ÷ 6 = 5.196152423.

I didn't round any of the numbers. Hopefully this is correct.

Sorry about the messy diagrams (never been good at creating them) and how long it took.

Answer:

$12

Step-by-step explanation:

Let the original price of bracelet be $ x.

$\therefore \: 6\% \: of \: x \: = \$.72 \\ \\ \therefore \: \frac{6}{100} \times \: x \: = \$.72 \\ \\ \therefore \: x = 0.72 \times \frac{100}{6} \\ \\ \therefore \: x = 0.12 \times 100 \\ \\ \huge \red { \boxed{\therefore \: x = \$12 }}$

Hence, original price of bracelet is $12.
