Answer:
x=17
Step-by-step explanation:
(5x-58)=(2x-7) ->(because of cosine-rule)
3x=51
x=17
I don't think Hailey is correct because 5 is half and you need to multiply the half.
Divide both the numerator and the denominator by 4, so 12/20 becomes 3/5.
<span>Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-2p' to each side of the equation.
-12 + -6p + -2p = 12 + 2p + -2p
Combine like terms: -6p + -2p = -8p
-12 + -8p = 12 + 2p + -2p
Combine like terms: 2p + -2p = 0
-12 + -8p = 12 + 0
-12 + -8p = 12
Add '12' to each side of the equation.
-12 + 12 + -8p = 12 + 12
Combine like terms: -12 + 12 = 0
0 + -8p = 12 + 12
-8p = 12 + 12
Combine like terms: 12 + 12 = 24
-8p = 24
Divide each side by '-8'.
p = -3
Simplifying
p = -3
