In triangle ABC, m&lt;A = 8x +12, m&lt;B = 5x+14, m&lt;C = 2x +4. What is the m&lt;A ? Need help....please
Elena L [17]
Triangle
m<A + m<B + m<C = 180
8x +12 + 5x+14 + <span>2x +4 = 180
15x + 30 = 180
15x = 180 -30
15x = 150
    x = 10

m<A   </span><span>= 8x +12
</span>m<A   = 8(10) +12
m<A = 80 + 12
m<A = 92

answer
m<A = 92

1. Solve for p in: -2(3p-6)+4(5p-8)=2(2p+3)+4
skad [1K]

Answer:

p = 3

Step-by-step explanation:

Hey there!

In order to find what p equals, we must first simply the equation to the most, then solve

SIMPLIFY

----------------------------------------------------------------------------------------------------------

-2 (3p - 6) + 4(5p - 8) = 2(2p + 3) + 4

-6p + 12 + 20p - 32 = 4p + 6 + 4

Now that we expanded the equation, we can combine all like terms

14p - 20 = 4p + 10

10p = 30

Now that we simplified the equation to the most, now we solve the equation

SOLVE

----------------------------------------------------------------------------------------------------------

10p = 30

p = 30/10

p = 3/1

p = 3
