Since you want to know the values of x, and y, plug in 0 for the x and y when you are solving, first I would be finding x so I would plug in 0 for y

14x + 16(0) = 58

14x = 58

x = 4.14285714286

Next do the same for y

14(0) + 16y = 58

16y = 58

y = 3.625

(This is on my quaturly check Help!!!) ABC and CBD are supplementary angles. m/ABC=(5x+12) and m/CBD=(13x+24).Complete all the p
Wewaii [24]

Answer:

Step-by-step explanation:

Part (A).

Angles ABC and CBD are the supplementary angles.

Therefore, m(∠ABC) + m(∠CBD) = 180°

Now substitute the measure of each angle in the equation,

(5x + 12)° + (13x + 24)° = 180°

18x + 36 = 180

18x = 180 - 36

18x = 144

x = 8

Part (B).

m∠ABC = (5x + 12)

             = 5(8) + 12

             = 52°

m∠CBD = (13x + 24)

             = 13(8) + 24

             = 104 + 24

             = 128°

Part (C).

We can check the results by adding measures of these angles.

m∠ABC + m∠CBD = 52 + 128

                               = 180°

Therefore, both the angles are supplementary angles which is already given.

<u>there </u><u>a</u><u>r</u><u>e</u><u> </u><u>3</u><u>1</u><u>4</u><u>.</u><u>5</u><u> </u><u>b</u><u>o</u><u>y</u><u>s</u><u> </u><u>in the school </u><u>.</u>

Answer:

Solution given

let boys be x and girls be y.

now

according to the question;

x+y=575

and

y=x-54

substituting value of y in equation 1.

x+x-54=575

2x=575+54

x=629/2

x=314.5
