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

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

A zoologist is recording the loss of wolves in her state. She notes the number of wolves, w, in the state on January 1. One year later, there were 84 wolves in the state, which is 23 fewer wolves than were in the state a year earlier. What is the number of wolves in the state on January 1? Which equation can be used to find the number of wolves in the state on January 1?

w−84=−23

w + 23 = 84

w−23=84

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

Answer:

For the first question, the answer would be 43.2%; if you want to round further, it would be 43%.

For the second question, the answer would be 65.9%; if you want to round further, it would be 66%.

Step-by-step explanation:

1st question:

315/220 = 1.4318181....

1.4318*100 = 143.18

143.18 - 100 = 43.18

2nd question:

315 + 50 = 365

365/220 = 1.659090....

1.6590*100 = 165.90

165.90 - 100 = 65.90
