Answer:

Pencil: $0.60 Rubber: $0.48

Step-by-step explanation:

Let the cost of a pencil be p and the cost of a rubber be r.

[tex]p+r=1.08[/tex]  (Equation 1)

[tex]4p=5r[/tex]  (Equation 2)

Divide both sides by 4:

[tex]p=\frac{5}{4} r[/tex]

Substitute this into Equation 1:

[tex]\frac{5}{4} r+r=1.08[/tex]

Multiply both sides by 4:

[tex]\frac{5}{4}r* \:4+r* \:4=1.08*4[/tex]

[tex]5r+4r=4.32[/tex]

[tex]9r=4.32[/tex]

Divide both sides by 9:

[tex]\frac{9r}{9}=\frac{4.32}{9}[/tex]

[tex]r=0.48[/tex]

Since r + p = 1.08,

[tex]p=1.08=0.48=0.60[/tex]

Answer:

-0.2+7k

Step-by-step explanation:

Rearrange the equation so that it is 1.8-2+7k

1.8-2=-0.2

You can't add 7k because it doesn't have a common variable

-0.2+7k

Hey there! I'm happy to help!

Let's call our length and width L and W respectively.

L=1/2W-4

L=18

Since L is equal to 18, we can just replace the L in the first equation with 18 and solve.

1/2W-4=18.

We add 4 to both sides.

1/2W=22

We divide both sides by 1/2.

W=44

Have a wonderful day! :D

Answer:

The answer is a  18= w/2-4

Answer:

(-8.5,9)

Step-by-step explanation:

((-8+(-9))/2=-8.5

(7+11)/2=9

(-8.5,9)

Answer:

(-8.5, 9)

Step-by-step explanation:

use midpoint formula

(-8 + -9) ÷2 , (7 + 11) ÷ 2

-17 ÷ 2 , 18 ÷ 2

-8.5 , 9

so the coordinates of the midpoint are (-8.5, 9)

Answer:

see explanation

Step-by-step explanation:

(1)

[tex]\frac{6}{2}[/tex] = [tex]\frac{4}{p}[/tex] ( cross- multiply )

6p = 8 ( divide both sides by 6 )

p = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]

(2)

[tex]\frac{n}{4}[/tex] = [tex]\frac{8}{7}[/tex] ( cross- multiply )

7n = 32 ( divide both sides by 7 )

n = [tex]\frac{32}{7}[/tex]

(3)

[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{4}[/tex] ( cross- multiply )

3x = 20 ( divide both sides by 3 )

x = [tex]\frac{20}{3}[/tex]

3s - 8 = 2s

First, let's subtract 3s from both sides

-8 = -s

Divide both sides by -1

8 = s

You have one solution which is s = 8

There is only a solution for the given equation 3s − 8 = 2s, s=8.

A mathematical equation is a claim that two expressions, which may contain variables or numbers, are equal. Equations are essential questions, and the main motivations for the development of mathematics have been efforts to methodically find answers to these questions.

It is given that the equation is,3s − 8 = 2s.

In order to find the value of s we have to simplify the given equations by applying the arithmetic operations.

3s - 8 = 2s

3s-2s= +8

s=8

Thus, the number of the solution for the given equation will be 1.

Answer:

x = 7 and y = 1

Step-by-step explanation:

Coordinates of Coffee shop = (12, 16)

Coordinates of Library = (16, 8)

School has been shifted to the new position so that distance of school is preserved from the coffee shop.

Coordinates of the new position of school = (15, 10)

Ratio in which distance between coffee shop and library is divided by the location of school is x : y.

If a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is divided into two parts by point (x, y) in the ratio of m : n,

x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]

y = [tex]\frac{my_2+ny_1}{m+n}[/tex]

From the points given in the picture,

15 = [tex]\frac{16x+8y}{x+y}[/tex]

15x + 15y = 16x + 8y

15y - 8y = 16x - 15x

7y = x

[tex]\frac{x}{y}=\frac{7}{1}[/tex]

Therefore, x = 7 and y = 1 will be the answer.

Answer:

[tex] MP = 29 [/tex]

Step-by-step explanation:

Given:

[tex] MN = 17 [/tex]

[tex] NP = 3y [/tex]

[tex] MP = 5y + 9 [/tex]

[tex] MN + NP = MP [/tex] (segment addition postulate)

[tex] 17 + 3y = 5y + 9 [/tex] (substitution)

[tex] 3y = 5y + 9 - 17 [/tex] (subtracting 17 from each side)

[tex] 3y = 5y + 8 [/tex]

[tex] 3y - 5y = 5y - 8 - 5y [/tex] (Subtracting 5y from both sides)

[tex] -2y = 5y - 8 - 5y [/tex]

[tex] -2y = - 8 [/tex]

[tex] y = 4 [/tex] (dividing both sides by -2)

[tex] MP = 5y + 9 [/tex]

Plug in the value of y

[tex] MP = 5(4) + 9 = 20 + 9 [/tex]

[tex] MP = 29 [/tex]

Answer:

  y = 5/6x +4/3

Step-by-step explanation:

The 2-point form of the equation for a line is a useful place to start.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (3 -(-2))/(2 -(-4))(x -(-4)) -2

  y = 5/6(x +4) -2

  y = 5/6x +20/6 -12/6

  y = 5/6x +4/3

Answer:

No,

Step-by-step explanation:

be a light pink and one would be a darker shade of pink.because

The given two batches doesn't have the same shade of pink because the proportion of 7 cups of red : 4 cups of white is greater than 5 cups of red : 3 cups of white.

A proportion is an equation in which two ratios are set equal to each other. In simple words, equivalent fraction are called as proportions.

Now it is given that,

Mai's pink contains- 5 cups of red paint and 3 cups of white paint

So, Ratio of red : white = 5 : 3

⇒ 5/3 = 1.67

Priya;s pink contains- 7 cups of red paint and 4 cups of white paint

So, Ratio of red : white = 7 : 4

⇒ 7/4 = 1.75

Thus, the proportion of 7 : 4 > 5 : 3

Thus, the given two batches doesn't have the same shade of pink because the proportion of 7 cups of red : 4 cups of white is greater than 5 cups of red : 3 cups of white.
