Lea earned $24 babysitting. She spent ⅔ of that amount on a gift for her bestie, ¼ on snacks. What fraction of her earning is left? How much money does she have left?

Answer:

B

Step-by-step explanation:

1) lets use elimination to solve this:

multiply 10x+4y=24 with 3 in order to get "4y" into "12y"

3(10x+4y=24)

30x+12y=72

now subtract both equations to eliminate 'y"

30x+12y=72

-

6x+12y=48

---------------------

24x=24

x=1

now substitute 1 in the above equation:

6(1)+12y=48

6+12y=48

12y=42

y=7/2

Answer:

you have to use the slope equation, which is (y2-y1) / (x2-x1)

3. (5-0)/(1 -(-8))

5/1+8

5/9

4. (3-3)/(-4 -8)

0/-12

the slope is 0

6. (-2-8)/(1-0.5)

-10/0.5

-20

7. (7-(-1))/ (4-4)

7+1/0

8/0

the slope is undefined

Answer:

I don't know

The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2) and this can be determined by using the given data.

Given :

After the dilation of 1/3 the coordinate of the triangle becomes:

[tex]\rm A(-2,2) \to A'(-2\times \dfrac{1}{3},2\times \dfrac{1}{3}) = A'\left(\dfrac{-2}{3},\dfrac{2}{3}\right)[/tex]

[tex]\rm B(3,6) \to B'(3\times \dfrac{1}{3},6\times \dfrac{1}{3}) = B'\left(1,2)[/tex]

[tex]\rm C(1,-2) \to C'(1\times \dfrac{1}{3},-2\times \dfrac{1}{3}) = C'\left(\dfrac{1}{3},\dfrac{-2}{3}\right)[/tex]

The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2).

Step-by-step explanation:

Under a clockwise rotation about the origin of 90°

a point (x, y ) → (y, - x ) , then

R(2, - 1 ) → R'(- 1, - 2 )

S(4, 0 ) → (0, - 4 )

T(1, 3 ) → T'(3, - 1 )

Answer:

It is an arithmetic sequence

Common difference is -4

Step-by-step explanation:

Here, we want to determine the type of sequence

As we can see, the difference between each of the terms is as follows;

13-17 = 9-13 = -4

What this mean is that we have a constant common difference

This simply shows that the sequence we have is an arithmetic sequence

The common difference is thus;

13-17 = 9-13 = -4

Answer:

Answer:

B

Step-by-step explanation:

Here, we want to choose the equation representing the time it will take if they worked together

Let the amount of tasks to be done be t

pedro will work at a rate of t/3

Camela will take t/2

So the joint rate will be

t/2 + t/3

This joint rate will be equal to 1

Thus, we have

t/2 + t/3 = 1

Answer:

multiply by 5, t = 14.5

Step-by-step explanation:

t/5 = 2.9 (multiply each side by 5)

t = 14.5

10 strawberries

Step-by-step explanation:

If Mike can pick 50 strawberries in 5 minutes then it is safe to assume that for 1 minute, Mike can pick 10 strawberries since you divide 50 by 5 in which Mike can pick a strawberry for every 6 seconds.

Answer:

65 miles per hour.

Step-by-step explanation:

To find the unit rate, we need to figure out how far we travel in one hour.

325/5 = 65/1

We travel 65 miles in one hour.

Answer:

65 mph (miles per hour)

Step-by-step explanation:

Because unit rate is a rate where the second quantity is one unit.

And to find miles per hour in this equation you have to divide 325 miles by 5 (because it is 5 hours) and you get 65.

Answer:

The correct option is;

D. -8·t² + 18·t + 6 = 10

Step-by-step explanation:

The given equation of the height toy cannon launched on top of a platform is given as follows;

h(t) = -8·t² + 18·t + 6...(1)

Where "h" represents the height in meters, at time "t" seconds after the ball is launched

When the height is 10 meters, we can write as follows;

The height of the ball, h(t) = 10

Therefore, by substituting the value of h(t) in equation (1), h(t) = -8·t² + 18·t + 6, when h(t) = 10 we get;

-8·t² + 18·t + 6 = 10.

Answer:

The x coordinate of the solution to the system of equations is 8

Step-by-step explanation:

We need to find the x coordinate of the solution to the system of equations?

[tex]x- 5y =23\\-2x - 6y =2[/tex]

Let

[tex]x- 5y =23--eq(1)\\-2x - 6y =2--eq(2)[/tex]

Multiply equation 1 with 2 and add both equations

[tex]2x- 10y =46\\-2x - 6y =2\\-------\\-16y=48\\y=\frac{48}{-16}\\y=-3[/tex]

So, we get the value of y = -3

Now, for finding x, put value of y in equation 1

[tex]x- 5y =23Put\:y=-3\\x-5(-3)=23\\x+15=23\\x=23-15\\x=8[/tex]

So, we get x = 8

The solution set is (8,-3)

So, the x coordinate of the solution to the system of equations is 8
