Answer:

Step-by-step explanation:

( 3x - 7 )° + ( 9x - 2 )° + ( x + 7 )° = 180°

13x = 182

x = 14

m ∠ A = ( 3 × 14 - 7 )° = 35°

m ∠ B = ( 9 × 14 - 2 )° = 124°

m ∠ C = ( 14 + 7 )° = 21°

sergij07 [2.7K]

Answer:

x=5/16

Step-by-step explanation:

Let's solve your equation step-by-step.

4x(−4)=−2−(−3)−6

Step 1: Simplify both sides of the equation.

4x(−4)=−2−(−3)−6

−16x=−2+3+−6

−16x=(−2+3+−6)(Combine Like Terms)

−16x=−5

−16x=−5

Step 2: Divide both sides by -16.

−16x

−16

=−5/−16

x=5/16

can I be the brainiest please!!
