Answer:

It would be 35

Step-by-step explanation:

Angle 1 and Angle 4 are equal so then you can solve for x.

7x = 3x + 20

x = 5

Then plug in 5 for x

7(5) = 35

Answer:

7, 11

Step-by-step explanation:

because those sides are congruent so their measurs are equal

3a+7=4a find a

b+11=2b find b

7=4a-3a,  subtract 3a from both sides so a=7

11=2b-b, subtract b from both sides so b=11

Answer:

The probability that Terry buys a sandwich and gets the bus is 0.36

Step-by-step explanation:

When two events are called independent, it means that the happening of one event doesn't affect the happening of other event.

Let A be the event that Terry buys a sandwich

Let B be the event that Terry gets the bus

Then

[tex]P(A) = 0.4\\P(B) = 0.9[/tex]

When two events are independent, their probabilities are multiplied i.e.

[tex]P(A\ and\ B) = P(A) * P(B)\\= 0.4 * 0.9\\= 0.36[/tex]

Hence,

The probability that Terry buys a sandwich and gets the bus is 0.36

Answer:

  AD= 8

  DC= 15

  Angle a= 112°

  Angle b= 68°

  Angle c= 112°

Step-by-step explanation:

We have to assume the figure is a parallelogram.

Opposite sides of a parallelogram are congruent, so ...

  BC = AD = 8

  AB = DC = 15

Opposite angles are congruent, and adjacent angles are supplementary.

  180° - ∠D = Angle a = Angle c = 112°

  ∠D = Angle b = 68°

Answer:

see explanation

Step-by-step explanation:

Under a rotation about the origin of 180°

a point (x, y ) → (- x, - y ) , thus

(0, 5 ) → (0, - 5 )

(- 1, 1 ) → (1, - 1 )

(- 3, 2 ) → (3, - 2 )

(- 4, 4 ) → (4, - 4 )

She is not correct, because there are no solutions. (Option C).

An equation refers to any mathematical statement that contains the equality sign. Now we can see in the equation that there is a negative sign before the absolute value.

Now we have;

–|2x – 10| – 1 = 2

–|2x – 10| = 3

This is not possible because the absolute value does not return a negative value and the expression can never equal 3.

Thus, she is not correct, because there are no solutions.

Answer: Vegan student gets 9/5 cheese slices

The rest of the 4 students get each: 5/5 slices of pepperoni + 1/2 slice of Pepperoni + 3/10 slice of cheese.

Step-by-step explanation:

6 slices of Pepperoni + 3 slices of cheese = 9 slices total.  We need to divide the slices among 5 students, 1 is vegan.

9 divided by 5 = 1 and 4/5 slices or  9/5 slices.

The 9 slices make 45/5 slices.

3 slices of cheese = 15/5 slices.

6 slices of pepperoni = 30/5 slices.

Vegan student gets 9/5 cheese slices. Leaving 6/5 slices or 12/10 slices of cheese, 12/10 divided by 4=3/10

The rest of the 4 students get each: 5/5 slices of pepperoni + 1/2 slice of Pepperoni + 3/10 slice of cheese.

5/5=10/10, 1/2=5/10, 3/10  

10/10 + 5/10 + 3/10 = 18/10=9/5 slices each person.

========================================================

Explanation:

The two points on this line are (-1,5) and (0,1)

Let's use the slope formula

m = (y2-y1)/(x2-x1)

m = (1-5)/(0-(-1))

m = (1-5)/(0+1)

m = -4/1

m = -4

The slope is m = -4

If we started at (-1,5) and moved down 4 and to the right 1, then we arrive at (0,1). The motion "down 4, right 1" is directly tied to the slope -4 since -4 = -4/1 = rise/run

The y intercept is b = 1 since this is the location where the graph crosses the y axis.

With m = -4 and b = 1, we go from y = mx+b to y = -4x+1

Answer:

[tex]y+1=\frac{-2}{3} (x+4)[/tex]

Step-by-step explanation:

you can use the equation point-slope of a line

(y-y1)= m(x-x1)

m is the slope =rise /run

to get from the lower point  on the line to the other you rise 4 units and run -6 units so m= -4/6= -2/3

now that you have the slope pick you need one point

pick any poin on the line for example (-4, -1)

now you substitute into the point-slope equation point (-4,-1) and slope -2/3

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

in standard form will be

y=[tex]\frac{-2x}{3} -\frac{2*4}{3} -1[/tex]

y=[tex]\frac{-2x}{3}- \frac{5}{3}[/tex]

Answer:

-2 or -2/1

Step-by-step explanation:

Since the equation is in y = mx + b form with m equaling the slope, we can see that -2 is in m's place, so -2 is the slope.

Answer: The statue is 9 feet tall.

Step-by-step explanation: Just double all of your values because 12 is 6x2.

Step-by-step explanation:

Hey there!

According to the figure;

9v = 31° + 4v + 44° { The exterior angle is equal to the sum of opposite adjacent interior angles}

9v-4v = 44°+31°

5v = 75°

v = 75°/5

Therefore, v= 15°.

Answer:

Angles 2, 3, 6, 7

Step-by-step explanation:

Since supplementary means to add up to 180 degrees, or a straight angle, we just find which angles are connected with a straight line.

These angles would be Angle 2 and Angle 3.

Since we have a whole figure, we also need to find the corresponding angles for Angle 2 and Angle 3. (Corresponding angles are the same degree as the original angle.)

The Corresponding angles to Angle 2 and Angle 3 are Angle 6 and Angle 7 respectively.

Thus, our answer is Angles 2, 3, 6, and 7.

Answer: Banquet Brothers has better deal.

Step-by-step explanation:

Given: Banquet Brothers sell a tray with 48 servings of pasta for $60.

Cost per serving = [tex]\$\dfrac{60}{48}=\$\dfrac{5}{4}=\$\ 1.25[/tex]

Cookin' Catering sells a tray with 30 servings of pasta for $72.

Cost per serving = [tex]\$\dfrac{72}{30}=\$\ 2.4[/tex]

Since, Cost per serving in Banquet Brothers < Cost per serving in Cookin' Catering

So, Banquet Brothers has better deal.
