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.

Explain how your work your knowledge of place value helps you divide a number in thousands by whole numbers to 10 give a example

Anna71 [15]

Place value is the value each digit has in its position: in order from higher to lower value, there is thousands, hundreds, tens, and ones.
When you divide by 10, you are moving (only once) every digit from its present place value to the right.
For example 6430 : 10= 643, you have moved every digit to the right, making the zero disappear (or better yet, separated by a hidden and in this case useless comma).

5) Derek was surfing through the internet for a good deal on t-shirts. Help Derek find the

AlladinOne [14]

Answer:

The first one

Step-by-step explanation:

To figure out which one is the best deal, for each one how much one t-shirt costs.

First deal:

3 t-shirts for $28.95

To figure out how much money one t-shirt would cost, you divide $28.95 by 3.

1 t-shirt = 28.95/3 = $9.65.

Second deal:

4 t-shirts for $39

Same thing as the last one, except since there are 4 t-shirts you divide $39 by 4.

1 t-shirt = 39/4 = $9.75

Third deal:

5 t-shirts for $49.95

This time you will divide 49.95 by 5.

1 t-shirt = 49.95/5 = $9.99

The last step is to compare the three deals, and since you are trying to find the one that costs the least you can see that the first deal is the best one, because $9.65 per shirt is cheaper than $9.75 and $9.99
