Answer:

14b.) RS = 60; ST = 36; RT = 96

Step-by-step explanation:

Since you have correctly solved for y = 7, all you need to do for b is to plug in y.

RS = 8(7) + 4 = 60

ST = 4(7) + 8 = 46

(You can add RS and ST or plug in for y for RT)

RT = 15(7) - 9 = 96

Answer:

angle x= 136

Step-by-step explanation:

angle on straight line =180

so we do 180 - 96 (angle y)=84

then:

angles in a triangle add up to 180

we do

84 (inside the triangle next to angle y) + 52 (angle z)= 136

180 (all angles in triangle) - 136 (angle y and z)=44

Now we know that the angle inside the triangle next to Angle x is 44

Angles on straight line =180

180-44= 136

Answer:

Step-by-step explanation:

triangle first:

= y=96

= z=52

= so , 180-96=84

= so, angle b = 84

= the corresponding side should be equal so, angle c = 84

= so x. = 180 - 84

= x = 96

= so , x = 96

so , this is the  triangle theory yehhaaaaa

Paulie's opportunity cost of producing a cup of ice cream is 4 T-shirts while Vinny's opportunity cost (C) of producing a t-shirt is 0.53

The table entries are given as:

          Ice Cream (cups) T-shirts (quantity)

Paulie 5.00                          20.00

Vinny 8.00                              15.00

Paulie's opportunity cost of producing a cup of ice cream is calculated by dividing the number of T-shirts by the cups of ice cream.

So, we have:

[tex]C = \frac{20.00}{5.00}[/tex]

[tex]C =4.00[/tex]

Similarly, Vinny's opportunity cost (C) of producing a t-shirt is calculated by dividing the cups of ice cream by the number of T-shirts

So, we have:

[tex]C = \frac{8.00}{15.00}[/tex]

[tex]C = 0.53[/tex]

Hence, Vinny's opportunity cost (C) of producing a t-shirt is 0.53

Answer:

x = 14°   ||       each angle has 108°

explanation:

first we need to find the total interior angle of this shape:

formula: ( n - 2 ) * 180  ..............where n is the number of sides

( 5 -2 ) * 180

540°

if all sides in the shape are equal, they must have same angle of 9x -18

5 ( 9x -18 ) = 540°

9x -18° = 108°

9x = 108° + 18°

9x = 126°

x = 14°

So each angle has: 9x - 18

                                9(14) - 18

                                108°

Answer: Choice D

Explanation:

I'll use the point-slope form to get the following

[tex]y - y_1 = m(x - x_1)\\\\y - 1 = \frac{3}{4}(x - (-4))\\\\y - 1 = \frac{3}{4}(x + 4)\\\\y - 1 = \frac{3}{4}x + \frac{3}{4}*4\\\\y - 1 = \frac{3}{4}x + 3\\\\y = \frac{3}{4}x + 3 + 1\\\\y = \frac{3}{4}x + 4 \ \ \text{... matches with choice D}\\\\[/tex]

You should find that plugging x = -4 into equation D will lead to y = 1 as a way to confirm the answer.

Answer:

D

Step-by-step explanation:

m = 3/4

point: (-4, 1)

We can use the slope-intercept form. We know one point, so we can use its coordinates for x and y. We also know the slope, so we use the slope for m. Then we solve for b.

y = mx + b

Substitute m with the slope.

y = (3/4)x + b

Use the x-coordinate of the given point for x and the y-coordinate of the given point for y.

1 = (3/4)(-4) + b

Solve for b.

1 = -3 + b

b = 4

Now that we know the value of b, we can write the equation of the line.

y = mx + b; m = 3/4; b = 4

y = 3/4 x + 4

Step-by-step explanation:

Because of isosceles triangle, AB = CB.

Because of the median, AD = CD.

Because of congruence of segments being reflexive, BD = BD.

By SSS, the triangles BAD and BCD are congruent.

Answer: B.

Using congruence postulate SSS we can prove that,

ΔBAD is congruent to ΔBCD.

Option B is the correct answer.

There are ways to prove that two triangles are congruent.

- Side-Side-Side (SSS) Congruence.

The three sides of one triangle are equal to the corresponding three sides of another triangle.

- Side-Angle-Side (SAS) Congruence.

The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.

- Angle-Side-Angle (ASA) Congruence.

The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.

- Angle-Angle-Side (AAS) Congruence.

We have,

BD is the median of ΔABC.

ΔABC is isosceles.

Using congruence postulate SSS.

We have,

ΔABC is isosceles.

This means,

AB = CB

AD = DC [ BD is median ]

BD = BD [ Common sides ]

ΔBAD is congruent to ΔBCD

Thus,

ΔBAD is congruent to ΔBCD

Answer:

3.5 : 7 > 1.2 : 2.5.

Step-by-step explanation:

1. Compare the ratios 4 : 5 and 2 : 3.

Solution:

Express the given ratios as fraction

4 : 5 = 4/5 and 2 : 3 =2/3

Now find the L.C.M (least common multiple) of 5 and 3

The L.C.M (least common multiple) of 5 and 3 is 15.

Making the denominator of each fraction equal to 15, we have

4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15

Clearly, 12 > 10

Now, 12/15 > 10/15

Therefore, 4 : 5 > 2 : 3.

2. Compare the ratios 5 : 6 and 7 : 9.

Solution:

Express the given ratios as fraction

5 : 6 = 5/6 and 7 : 9 =7/9

Now find the L.C.M (least common multiple) of 6 and 9

The L.C.M (least common multiple) of 6 and 9 is 18.

Making the denominator of each fraction equal to 18, we have

5/6 = (5 ×3)/(6 ×3) = 15/18 and 7/9 = (7 ×2)/(9 ×2) = 14/18

Clearly, 15 > 14

Now, 15/18 > 14/18

Therefore, 5 : 6 > 7 : 9.

3. Compare the ratios 1.2 : 2.5 and 3.5 : 7.

Solution:

1.2 : 2.5 = 1.2/2.5 and 3.5 : 7 =3.5/7

1.2/2.5 = (1.2 ×10)/(2.5 ×10 ) = 12/25 and 3.5/7 = (3.5 ×10)/(7 ×10) = 35/70 = 1/2

[We removed the decimal point from the ratios now, we will compare the ratio]

Now find the L.C.M (least common multiple) of 25 and 2

The L.C.M (least common multiple) of 25 and 2 is 50.

Making the denominator of each fraction equal to 50, we have

= 12/25 = (12 ×2)/(25 ×2) = 24/50 and 1/2 = (1 ×25)/(2 ×25) = 25/50

Now, 25/50 > 24/50

Therefore, 3.5 : 7 > 1.2 : 2.5.

Sqaure has  a side  let say p = 3x + 12

As the formula for square area is

    Area = A = p² or length × width

As square  has all equal  side

So   ( 3x + 12 ) ( 3x + 12 )

   ⇒  9x² + 36x +36x + 144

         9x² + 72x + 144

    OR  take 9 common

Answer:

x = 1

y = 0

Step-by-step explanation:

You did a great job solving one of the equations for a single variable. You solved for x. But what your paper shows is that...it jind of looks like you were going to substitute the 2y+1 into y. BUT you need to substitute it into x.

-4x + 3y = -4

x = 2y + 1

Fill in 2y + 1 into x in the first equation.

-4(2y+1) + 3y = -4

Now you have an equation in one variable. There are only y's in this equation. Next, distribute.

-8y - 4 + 3y = -4

combine like terms.

-5y - 4 = -4

add 4 to both sides.

-5y = 0

divide by -5

y = 0

It's okay that it cam out to be zero. Its fine!

y=0

Put it back in one of the original equations to find x.

x = 2y + 1

x = 2(0) + 1

x = 1

The solution is

x=1

y=0

You can write this as an ordered pair.
