Answer:

There is one solution.

x = -17

<em>Proof and step-by-step explanation:</em>

Step 1: <em>Add the numbers</em>

3x-7 = 4+6+4x

3x-7 = 10+4x

Step 2: <em>Move</em><em> </em><em>terms</em>

3x-7 = 10+4x

3x-4x = 10+7

Step 3: <em>Collect the like terms and calculate the sum</em>

3x-4x = 10+7

-x = 17

Step 4: <em>Change the sign by multiplying both sides by -1</em>

-x (×-1) = 17 (×-1)

x = -17

I hope this helped ! :)

ANSWER ASAP PLEASE FOR BRAINLIEST

Lelechka [254]

Answer:

You have to multiply all the sides by 4.

B to C = 2.8*4

2.8 * 4 = 11.2

B to A = 3*4

3*4 = 12

A to C = 2.2*4

2.2*4 = 8.8

Hope this helped!

Two angles are complementary. The first angle is 2x degrees. The second angle is (x+30) degrees. Determine the larger angle

Molodets [167]

larger angle = 50°

complementary angles sum to 90° , hence

2x + x + 30 = 90

3x + 30 = 90 ( subtract 30 from both sides )

3x = 60 ( divide both sides by 3 )

x = 20

thus 2x = 2 × 20 = 40° and x + 30 = 20 + 30 = 50°

the larger angle is x + 30 = 50°
