In basketball there are 1,2, and 3 point shots. In the last game sarah scored a total of 25 points by making 13 total baskets. S
ollegr [7]

Answer:

3 , 6 , 4

Step-by-step explanation:

Given:

There are three groups of shots in basketball.

First group carry = 1 point

Second group carry = 2 points

Third group carry = 3 points

Sarah scored a total of 25 points by making 13 total baskets.

She made twice as many 2 point shots as she did 3 point shots.

Question asked:

How many of each type of shot did she make ?

Solution:

Let number of baskets, she made which carry 3 points = x

Then, number of baskets, she made which carry 2 points = 2x

Total number of baskets, she made = 13

Then, number of baskets, she made which carry 1 points = 13-(x+2x)=13-3x

Now,

Sarah scored a total number of points = 25

3\times x+2\times2x+1(13-3x)=25\\3x+4x+13-3x=25\\4x+13=25

Subtracting both sides by 13

4x=25-13\\4x=12

Dividing both sides by 4

x=3

By substituting the value:-

Number of baskets, she made which carry 3 points = x = 3

Number of baskets, she made which carry 2 points = 2x = 2\times3=6

Number of baskets, she made which carry 1 points = 13-3x=13-3\times3=13-9=4

Thus, she made 3 baskets of 3 points, 6 baskets of 2 points and 4 baskets of 1 point.

The length of A"B" is 20 units

<h3>How to determine the length of A'B'?</h3>

From the figure, we have:

A = (1, 4)

B = (4, 8)

The distance AB is:

AB = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2

So, we have:

AB = \sqrt{(1 -4)^2 + (4-8)^2

Evaluate

AB = \sqrt{25

This gives

AB = 5

The scale factor of dilation is 4.

So, we have:

A'B' = 5 * 4

Evaluate

A'B' = 20

Hence, the length of A"B" is 20 units

Sveta_85 [38]

Answer:

x=amount invested at 7%

2x=amount invested at 8%

3x=amount invested at 9%

interest=principal*rate*time (time=1 year)

$150=0.07x+0.08*2x+0.09*3x

$150=0.07x+0.16x+0.27x

$150=0.50x

$1500=5x

x=$300 invested at 7%

2x=$600 invested at 8%

3x=$900 invested at 9%
