Answer:

x=-3

<ABD=88

<CBD=23

Step-by-step explanation:

We know that <ABC is made up of 2 angles: <ABD and <CBD.

We also know that the m<ABC is 111.

Therefore, <ABD and <CBD added together must equal 111.

<ABD+ <CBD =111

We know that <ABD is -10x+58 and <CBD is 6x+41, so we can substitute these in.

-10x+58+6x+41=111

Combine like terms

(-10x+6x)+(58+41)=111

-4x+99=111

Now we need to solve for x. First, move all the constants to the same side. Subtract 99 from both sides, since 99 is being added to -4x.

-4x+99-99=111-99

-4x=12

Next, divide both sides by -4, since -4 and x are being multiplied.

-4x/-4=12/-4

x=-3

Now we know x, and can substitute it in to find the angle measures.

<ABD

-10x+58

-10(-3)+58

30+58

88

<CBD

6x+41

6(-3)+41

-18+41

23

[tex]m \angle ABD = 88^{\circ}\\m \angle CBD = 23^{\circ}[/tex]

Given:

m∠ABC = 111∘

m∠ABD = (-10x+58)∘

m∠CBD = (6x+41)∘

First, find the value of x by creating an equation

Thus:

[tex]m\angle ABD + m \angle CBD = m \angle ABC[/tex] (angle addition postulate)

Substitute

[tex](-10x+58) + (6x+41) = 111[/tex]

Solve for x

[tex]-10x+58 + 6x+41 = 111[/tex]]

Add like terms

[tex]-10x+58 + 6x+41 = 111\\-4x + 99 = 111\\-4x = 111 - 99\\-4x = 12\\[/tex]

Divide both sides by -4

[tex]x = -3[/tex]

Find m∠ABD and m∠CBD by plugging in the value of x

[tex]m\angle ABD = -10x + 58 \\m\angle ABD = -10(-3) + 58 \\m\angle ABD = 88^{\circ}[/tex]

[tex]m \angle CBD = 6x + 41\\m \angle CBD = 6(-3) + 41\\m \angle CBD = 23^{\circ}\\[/tex]

Therefore:

[tex]m \angle ABD = 88^{\circ}\\m \angle CBD = 23^{\circ}[/tex]

(How much it grew in the last year.)

Answer:

135 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h(a + b)

where h is the height and a, b the parallel bases

Here h = 9, a = 13 and b = 17 , thus

A = [tex]\frac{1}{2}[/tex] × 9 × (13 + 17)

   = 0.5 × 9 × 30

   = 135 cm²

Answer:

16 cups of sugar

Step-by-step explanation:

27 x 2 2/3 = 72  So 2 2/3 x 6 = 16  

If 6 cups of sugar is used to make 27 cookies. Then 16 cups of sugar is used to make 72 cookies.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

Savannah is baking cookies with a recipe that calls for 6 cups of sugar to make 27 cookies.

We need to find how much sugar she has to add to make 72 cookies.

To find this we have to form an equation.

Let x be number of cups of sugar to make 72 cookies

6/27=x/72

Apply cross multiplication

72×6=27x

432=27x

Divide both sides by 27

x=16

Hence, 16 cups of sugar is required to make 72 cookies.

Answer:

1)  y = -3x + 9

2) y = -3/4x + 6

3) y = x - 5

Step-by-step explanation:

1) 3x + y - 7 = 2

            +7   +7

        3x + y = 9

       -3x        -3x

                y = -3x + 9

2) 3x + 4y = 24

  -3x           -3x

          4y = -3x + 24

          4        4      4

          y = -3/4x + 6

3) x - y = 5

  -x        -x

      -y = -x + 5

       -1     -1   -1

        y = x - 5

Answer:
