Answer:

a.

P + 5N 28

Step-by-step explanation:

The value of the coins is 28 cents. This means that if one were to account for the total money, it would amount to 28. So one would multiply the number of nickles by 5, (because one nickel is 5 cents), and the number of pennies by 1, (because a penny is one cent). The one would add the resulting values up to attain 28. The equation given in option A represents that, hence it is the correct answer.

Answer:

x= -7.27

Step-by-step explanation:

-81 = 5x + 3x + 3x - 1

combine all like terms

-81=11x-1

add 1 on both sides

-81=11x-1

+1 +1

-80=11x

divide by 11 on both sides to get x by itself

-80/11=11x/11

x=-7.27

Answer:

C

Step-by-step explanation:

h=10 so plug that into the given equation

c=3(10) +50

c=30+50

c=80

Answer: C, c = $80

Step-by-step explanation:

c = 3h + 50

c = 3 (10) + 50

c = 30 + 50

c = 80

The total cost is $80

Answer:

Option (4)

Step-by-step explanation:

x              g(x)            Ist difference          IInd difference        Ratio

1              13                      -                                   -                        -

2              3                3 - 13 = -10                         -                       [tex]\frac{3}{13}[/tex]  

3             -3               -3 - 3 = -6                   -6 - (-10) = 4            [tex]\frac{-3}{3}=-1[/tex]

4             -5               -5 - (-3) = -2                -2 - (-6) = 4             [tex]\frac{-5}{-3}=\frac{5}{3}[/tex]

5             -3               -3 - (-5) = 2                   2 - (-2) = 4            [tex]\frac{-3}{-5}=\frac{3}{5}[/tex]

This table depicts,

1). Ist difference is not common

2). IInd difference is common

3). Ratio is not common

Therefore, this table represents a quadratic function because the second difference are all the same value.

Answer:

[tex]x = 3.3cm[/tex]

Step-by-step explanation:

Given

Shape: Pentagon

Small

[tex]Bottom = x[/tex]

[tex]Left = 7cm[/tex]

Big

[tex]Bottom = 7cm[/tex]

[tex]Left = 15cm[/tex]

Required

Find x

From the question, we understand that the big pentagon is a dilation of the small pentagon.

What this means is that; both pentagons will have the same equivalent ratio.

The equivalent ratio, in this case is calculated using

[tex]Ratio = \frac{Bottom}{Left}[/tex]

For the small pentagon:

[tex]Ratio = \frac{x}{7cm}[/tex]

For the big pentagon:

[tex]Ratio = \frac{7cm}{15cm}[/tex]

Equate both ratios:

[tex]\frac{x}{7cm} = \frac{7cm}{15cm}[/tex]

[tex]\frac{x}{7cm} = \frac{7}{15}[/tex]

Cross multiply

[tex]15 * x = 7cm * 7[/tex]

[tex]15 * x = 49cm[/tex]

Make x the subject

[tex]x = \frac{49cm}{15}[/tex]

[tex]x = 3.267cm[/tex]

[tex]x = 3.3cm[/tex] --- approximated

Answer:

9

Step-by-step explanation:

you can set up a proportion for it (i included a picture of it)

Answer:

I am just doing this to confirm the other person is right. It is 9.

Step-by-step explanation:

Answer:

Thus, the number of sides: n ≈ 13  (rounded to the nearest whole number).

Step-by-step explanation:

We know that the formula of the sum of the measures of the interior  angles of a polygon

Sum = (n-2) × 180°

where

n is the number of sides

In your case, since the sum of the interior angles is 1930°, then

1930° = (n-2) × 180°

so we can determine the number of sides n, such as

1930 / 180 = n-2

[1930 / 180] + 2 = n

n ≈ 12.7

If 12.7 rounded to the nearest whole number, then

n ≈ 13

Thus, the number of sides: n ≈ 13 (rounded to the nearest whole number).

Answer:

B

Step-by-step explanation:

s+s+s+s+12 = 20. s=2

4(s+3)

4(2+3)

4(5)=20

Hey there!

s + s + s + s + 12

= 1s + 1s + 1s + 1s + 12

= 2s + 2s + 12

= 4s + 12

So, we’re looking for something that’s equivalent to: 4s + 12

• Option A.
4s + 3 ≠ 4s + 12

Option A. is wrong because it is NOT equivalent to the given equation

• Option B.
4(s + 3)

= 4(s) + 4(3)

= 4s + 12

Thus, this mean Option B. could possibly be your answer.

• Option C.

4s(s + 3)

= 4s(s) + 4s(3)

= 4s(s) + 3(4s)

= 4s^2 + 12s

Option C. is wrong because it is NOT equivalent to the given equation as well.

• Option D.
4 + s + 12

COMBINE the LIKE TERMS

= 16 + s

= s + 16

Option D. is wrong because it isn’t equivalent to the given equation as well.

Therefore, your answer is:

Option B. 4(s + 3)

Good luck on your assignment & enjoy your day!

Answer:

The slope is -1/6

Step-by-step explanation:

We simply use the slope formula here

Mathematically, we have this as;

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

thus;

m = (10-8)/(-21 + 9) = 2/-12 = -1/6
