Answer: 57 degrees

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

Explanation:

A is complementary to B, so A+B = 90. Similarly, B+C = 90 (since C is complementary to B).

A+B = 90

(3x+y)+(x+4y+2) = 90 ... substitution

4x+5y+2 = 90

4x+5y = 90-2

4x+5y = 88

Now let's set up another equation and solve for x

B+C = 90

(x+4y+2)+(3y-3) = 90 ... substitution

x+7y-1 = 90

x = 90+1-7y

x = 91-7y

Go back to the first equation and plug in x = 91-7y. Solve for y.

4x+5y = 88

4(x)+5y = 88

4(91-7y)+5y = 88 ... replace x with 91-7y

364-28y+5y = 88

364-23y = 88

-23y = 88-364

-23y = -276

y = -276/(-23)

y = 12

Now that we know the value of y, we can use it to find x

x = 91-7y

x = 91-7(12) ... replace y with 12

x = 91-84

x = 7

So the x and y values are x = 7 and y = 12. We'll use both of these values to compute the measure of angle B

Angle B = (x+4y+2) degrees

Angle B = (7+4*12+2) degrees

Angle B = (7+48+2) degrees

Angle B = 57 degrees

6.4/8 = y/6 = x/7

0.8/1 = 4.8/6 = 5.6/7

6.4/8 = 4.8/6 = 5.6/7

x = 5.6 ; y = 4.8

I think that’s how you do it but not 100% sure

Y=3x+18 <br> -12x+4y=-24 linear system of equations
solong [7]

Answer:

Step-by-step explanation:

Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x

-12x+12x+72=-24

The xs cancel, which leaves you with 72=-24

Since 72 cannot equal -24 there is no answer to this system of equations
