Carla and Rob left a 15% tip after having lunch at a restaurant. The amount of the tip was $3. Carla’s lunch cost $12. Write an equation you can use to find x, the cost of Rob’s lunch.

Answers

Answer:

0.15(x + 12) = 3

Step-by-step explanation:

The cost of the lunch before the tip was 12 + x

The tip is 15% of the cost of lunch: 0.15(x + 12)

The tip was $3

0.15(x + 12) = 3

Answers

Answer:

2 and 7 are alternate exterior angles

Alternate exterior angles are angles that are on different sides of the transversal and on the outside of the parallel lines. There is a theorem that says that alternate exterior angles are congruent if two parallel lines are cut by a transversal.

What is the value of y in the solution to the system of equations?

One-thirdx + One-fourthy = 1

2x – 3y = –30

Answers

Answer:

y-value = 8

Step-by-step explanation:

1/3x + 1/4y = 1 is the same as 4/12x + 3/12y = 1

which is the same as (4x + 3y)/12 = 1

which is the same as 4x + 3y = 12

add both equations and the 'y' will cancel and you will have 6x = -18

x = -3

2(-3) - 3y = -30

-6 - 3y = -30

-3y = -24

y = 8

Answer:8

How do you solve for X?

Answers

Answer:

<L+<M+<N=180

<NLM and <XLN are supplementary meaning their angle measure add to 180.

therefore,44+46+L=180

90+L=180

l=90

If l=90 then the <NLX is also 90 since they are supplementary angles

therefore, 3x+42=90

3x=48

x=16

(1,3) should be the answer due to the fact that both lines intersect at that point.

Step-by-step explanation:

What point is on both lines y=12x+3 and y=x+1

(no graph)

Answers

Step-by-step explanation:

by having two equations that have the same point, you can set the two equations equal to each other

y = 12x + 3, y = x + 1

12x + 3 = x + 1

11x = -2

x = -2/11

when you find the the x value, plug it back into either one of the equations

y = x + 1

y = (-2/11) + 1

y = 11/11 - 2/11

y = 9/11

the point (solution):

(-2/11, 9/11)

Answer:

(-2|11, 9|11)

A circle is graphed on a coordinate grid. Its center is at (3, 4), and the circle passes through point (3, 1). What is the approximate area, in square units, of the circle? (Use 3.14 for π.)

Answers

Answer:

it is either 18.84 or 31.40

Step-by-step explanation:

just do it in your head

The area of the circle is 28.26 square units

The center of the circle is given as:

[tex](a,b) = (3,4)[/tex]

The circle passes through the following point

[tex](x,y) = (3,1)[/tex]

Start by calculating the radius using the following distance formula

[tex]r = \sqrt{(x -a)^2 + (y - b)^2}[/tex]

So, we have:

[tex]r = \sqrt{(3 -3)^2 + (4 - 1)^2}[/tex]

[tex]r = \sqrt{9}[/tex]

Square both sides

[tex]r^2 = 9[/tex]

The area of the circle is then calculated as:

[tex]Area = \pi r^2[/tex]

So, we have:

[tex]Area = 3.14 \times 9[/tex]

[tex]Area = 28.26[/tex]

Hence, the area of the circle is 28.26 square units

A sales person works 40 hours a week at a job where he is being offered two options A pays 19.00 per hour B commission rate of 8% on weekely sales how much in a given week does he need to sell to earn the same amount with each option?

Answers

Answer:

$9,500= sales

Step-by-step explanation:

Giving the following information:

Number of hours= 40

Commission= 8%

Fixed salary= $19 per hour

First, we need to calculate the weekly salary of option A:

Weekly salary= 40*19

Weekly salary= $760

Now, the sales required in option B to equal option A:

Weekly salary= commission rate*sales

760 = 0.08*sales

760/0.08= sales

$9,500= sales
