Answer:

Cost of haircut = $93

Cost of colouring hair = $31

Step-by-step explanation:

Let

Cost of haircut = x

Cost of colouring hair = y

The equations

x + 2y = 217 (1)

2x + y = 155 (2)

From (1)

x = 217 - 2y

Substitute x = 217 - 2y into (2)

2x + y = 155

2(217 - 2y) + y = 155

434 - 4y + y = 155

-3y = 155 - 434

-3y = -279

y = -279 / -3

= 93

y = $93

Substitute y = 93 into (1)

x + 2y = 217

x + 2(93) = 217

x + 186 = 217

x = 217 - 186

= 31

x = $31

Cost of haircut = $93

Cost of colouring hair = $31

Step 1: Define

We have a right triangle triangle. We can use trig to find the missing length.

Step 2: Identify Variables

POV from the angle measure

Angle = 64°

Opposite = 13

Adjacent = x

Step 3: Solve for x

Answer:

x = 2

Step-by-step explanation:

x/6 + 1 = 2x - 8/3 (first you want to multiply by 6 on both sides to get rid of x/6)

x + 6 = 12x - 16 (add 16 on both sides)

x + 22 = 12x (subtract x on both sides)

22 = 11x (divide by 11 on both sides)

2 = x

Hope this helps ya!!

Explanation:

Start at x = 3 on the x axis. Move up until you reach g(x), then move to the left to hit the y axis. You should arrive at y = 3.

That y value is the input to the f(x) function.

Plugging x = 3 into the f(x) function has us draw a vertical line down to f(x) and then go horizontally until we reach y = -2.

Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

A recipe requires 1 (2/3) cups of sugar.

That is 1 recipe requires = 1(2/3) cups of sugars

                                        = 5/3 cups of sugar

Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :

1 recipe requires = 5/3 cups of sugar

1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar

3/2 recipe requires = (5/3) x (3/2) cups of sugar

3/2 recipe requires = 5/2 cups of sugar or 2.5  cups of sugar.

Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.

Answer:

Independent Variable: Number of bagels bought

Dependent Variable: Total cost because it depends on the number of bagels bought.

Function: N(x)=1.75x

So, if x is the number of bagels bought, N(14) means that 14 bagels were bought. So you multiply 14 by the price; 1.75. So, N(x)=1.75*14 = $24.5

Step-by-step explanation:

Answer:

The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.

A function relating these variables is V(x) =1.75x.

So V(14) = 24.5, meaning 14 bagels will cost 24.5 dollars.

Answer:

1 inch of drawing = 45 feet

Step-by-step explanation:

Given that:

Length between the bases on a baseball field = 90 feet

As per the scale drawing, the distance between the bases is equal to 2 inches.

To find:

Length of one inch on the drawing is equal to actual length of how many feet?

Solution:

First of all, let us learn about the scale drawings.

Scale drawings are a way to represent the big real world measurements on a paper.

Therefore, small measurements are used to represent the bigger real world measurements.

Here, it is given that:

2 inches on scale is equal to 90 feet of actual length.

Therefore,

1 inch on scale is equal to [tex]\frac{90}{2}[/tex] = 45 feet of actual length.

Therefore, 1 inch of drawing = 45 feet

Answer:

y = 2, x = 0

Step-by-step explanation:

2x + 4y = 8

x = 3y - 6

2x + 4y = 8

2 ( 3y - 6 ) + 4y = 8

10y - 12 = 8

10y = 20

y = 2

x = 3y - 6

x = 3 ( 2 ) - 6

x = 0

Answer/ explanation: -10 for sure :)

The next two terms after -40 in this pattern are 60 and -160.

The difference between every two subsequent words in a sequence is the same; this is known as an arithmetic progression (AP). An equation for the previous block of the AP may be derived from this kind of development. For instance, the sequence 2, 6, 10, 14,... is a mathematical progression (AP) because it fits a pattern where every other number is acquired by adding 4 to the respective period.

The given data is,

-10, 20, -40

From -10 to 20 it is multiplied by 2 with a positive sign, and from 20 to -40 it is multiplied by 2 with a negative sign. Similarly, the next two numbers are 80 and -160.
