In a basketball game, Tatiana made 23 baskets. Each of the baskets was worth either 2 or 3 points, and Tatiana scored a total of

53 points. Let x represent the number of two-point baskets she made and y represent the number of three-point baskets she made . Write a system of equations to represent the situation and solve the system to find out how many two point and three point baskets Tatiana made.

X+y=23 (x and y added equal the number of baskets made)

2x+3y=53 (since each basket is worth a certain amount of points, x and y must be multiplied by their amount of baskets and added together to get the total number of points)

Hope this helps!

Answer:

<h2>Tatiana scored 7 three points baskets, and 16 two-points baskets.</h2>

Step-by-step explanation:

Givens:

  • Tatiana made 23 baskets.
  • x represents the two-point baskets.
  • y represents the three-point baskets.
  • Tatiana scored 53 points.

The expression for the 23 baskets made by Tatiana would be:

x+y=23

In words, the sum of both type of scored baskets sum 23.

The expression for the total points scored would be:

2x+3y=53

In words, baskets of two points and three points sum 53 total points scored by Tatiana.

Now, we isolate x in the first equation and replace it in the second equation:

x=23-y\\2(23-y)+3y=53\\46-2y+3y=53\\y=53-46\\y=7

Replacing this value in the first equation, we have:

x+y=23\\x=23-7=16

Therefore, Tatiana scored 7 three points baskets, and 16 two-points baskets.

Answer:

#15) B. 30 mn^5

#17) B. 1/2

Step-by-step explanation:

<h2>#15:</h2>

The area of a trapezoid is given in the formula: 1/2(a + b) * h, where a is the length of the top of the trapezoid, b is the length of the bottom of the trapezoid, and h is the height of the trapezoid.

All of these measurements are given so all that you need to do is to substitute these values into the formula.

Substitute 3 for a, 9 for b, and 5 for h.

  • 1/2(3 + 9) * 5

Solve inside the parentheses first. Add 3 and 9.

  • 1/2(12) * 5

Multiply 12 and 1/2 together.

  • 6 * 5

Multiply 6 and 5.

  • 30

We need to figure out if the area is to the 5th or 6th power. When we added 3 and 9 together, we combined like terms so the exponent stayed to the 3rd power.

After multiplying this ^3 by the 5mn^2, the exponent becomes to the 5th power because you add exponents when multiplying.

Therefore the final answer is B. 30 mn^5.

<h2>#17:</h2>

When going down from 32 to 8 to 2, you can see that each number is being divided by 4.

32 / 4 = 8...

8 / 4 = 2...

So to find the next number in this sequence you would divide 2 by 4.

  • 2 / 4 = 1/2

The answer is B. 1/2.

Peter's Party Zone sells cups in packages of 666 and plates in packages of 888.
Amiraneli [1.4K]
Prime factorize the two numbers:

666 = 2 x 3 x 3 x 37
888 = 2 x 2 x 2 x 3 x 37

Notice I lined up all the numbers into columns. If they appear for both numbers they are paired. The lowest common multiple is the product of all the unique columns:

LCM = 2 x 2 x 2 x 3 x 3 x 37 = 2664

You can use this strategy for as many numbers as you want. Also, you could find the greatest common factor by multiplying only the paired columns.
