Answer:

1.5x+12=26

Step-by-step explanation:

Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

Imagine cutting up a pizza into 5 slices

If you take 2 slices, then you take 2 out of the 5, so the fractional amount you took is 2/5 of the full pizza.

If your friend takes 3 slices, then she or he takes 3/5 of the full pizza

Adding the two fractional amounts should get us back to 1 full pizza, which is why 2/5+3/5 = 1.

-----------

We could say this:

2/5 + 3/5 = (2+3)/5 = 5/5 = 1

Dividing any number over itself, as long it's not zero, always leads to 1.

So that's why 5/5 = 1.

Answer:

A = 64 pi

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

The radius is 8

A = pi * 8^2

A = 64 pi

Answer:

B. 63

Step-by-step explanation:

There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.

Therefore:

(6 + 3)/3 = x/21

9/3 = x/21

3 = x/21

Cross multiply

21*3 = x

63 = x

x = 63

Answer:

4.2

Step-by-step explanation:

If they're similar, the fraction between their sides need to be equal, so do this:

2/1.4 = 6/MN

6•1.4/2 = MN

MN = 4.2

Answer: you said help so I’m not going to give the actual answer, just how to do it.

Step-by-step explanation:

You have to find the answer first. You work out the top and then you work out the bottom. Then divide the top by the bottom. YIU will get a number woth a power. The power is x that is your answer.

Answer:

D. (–2, –2); minimum

Step-by-step explanation:

It’s D you got to see the lowest part of the graph and you will call it mini except if the graph was going down you will call that point maximum.

Answer:

D. (-2, -2); minimum

Step-by-step explanation:

The vertex is the where the curve turns up/down which divides the figure into two halves.

From the given graph, the graph turns up at (-2, -2) , the graph moves down, therefore, the vertex (-2, -2); minimum.

Hope this will helpful.

Thank you.

Answer:

x= 4, y = -1

Step-by-step explanation:

2x-3y=11

3x+3y=9

do addition and you should get

5x=20

x=4

plug in x into any equation

12+3y=9

3y= -3

y=-1

Answer: 45.725 ( i think)

Step-by-step explanation: 2.325 + 27.9 + 15.50

Answer:

v = - 2

Step-by-step explanation:

Given

- 12 = 2 + 5v + 2v ( subtract 2 from both sides )

- 14 = 7v ( divide both sides by 7 )

- 2 = v

Answer:

15 + x(.5) = 24 ; x = 18

Step-by-step explanation:

15 + 18(.5) = 24

15 + 9 = 24

Step-by-step explanation:

t is the number of ride tickets she can buy.

=>

[tex]15 + t \times 0.5 \leqslant 24[/tex]

she has to pay $15 just for entering. the rest of the money she can use for ride tickets.

so, whatever she does, she has to stay inside the $24 limit, as she does not have more money.

the $15 admission goes off the $24 available money. that leaves $9.

each ride ticket costs $0.50, so she can buy max. 9/0.5 = 18 tickets. she can buy fewer tickets, but she cannot buy more than these 18 tickets.

so, again

[tex]15 + t \times 0.5 \leqslant 24[/tex]

[tex]t \times 0.5 \leqslant 24 - 15 = 9[/tex]

[tex]t \times 0.5 \leqslant 9[/tex]

[tex]t \leqslant 9 \div 0.5 = 9 \div (1 \div 2) = 2 \times 9 \div 1 \\ = 18[/tex]

[tex]t \leqslant 18[/tex]

Answer:

A. $56

Step-by-step explanation:

the change of cost =

[7(10) + 28] - [7(2) + 28] = 98-42=56

Answer:

1/16

Step-by-step explanation:

There is a 1/2 chance to flip a heads.

So, in this case, we would multiply 1/2 four times in reference to the coins being flipped a total of 4 times to find its probability.

1/2 x 1/2 x 1/2 x 1/2 = 1/16

Thus, there is a 1/16 chance that you'd get heads four times in a row.

Answer:

The first one is a square! The second is none of these because its a trapezoid

Step-by-step explanation:

Answer:

7. all of the above

9. none of these

Step-by-step explanation:

graph number 7

you will see from the diagonal test that the diagonals of this shape are congruent. All four angles in the interior are congruent making it a rhombus. The outside side lengths are all equal to 6.71. Making it a rectangle. The definition of a square is if it is both a rectangle and a rhombus then it is a square.

graph number 9

you can plainly see that this is a trapazoid which is none of either of these choices.

hope this helps.

Answer: The area of the figure is 24 units.

Step-by-step explanation:

After plotting, the given points on the graph, we can observe that it is a parallelogram(opposite sides are equal and parallel)

Height = 4-1 = 3 units

Base = 2-(-6) = 8 units

Area of parallelogram = Base x height

= 8 x 3 square units.

= 24  square units.

Hence, the area of the figure is 24 units.
