x = the remaining student's score

(2(30) + 1(30) + 3(80) + x)/8 = 50

[multiply each side by 8]

2(30) + 1(30) + 3(80) + x = 400

[simplify]

60 + 30 + 240 + x = 400

330 + x = 400

[subtract 330 from each side]

x = 70

Lindsey Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 867 points. The number of two-point field goals that Lindsey made was 66 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 36 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season. How many free throws, 3 pointers, and 2 pointers did she make?

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Total point = 867

Let :

number of 3 point goals = p

Number of 2 point goals = 2p - 66

Number of 1 point goals = (2p - 66) - 36 = 2p - 102

Hence,

3p + 2(2p - 66) + 2p - 102 = 867

3p + 4p - 132 + 2p - 102 = 867

3p + 4p + 2p - 234 = 867

9p - 234 = 867

9p = 867 + 234

9p = 1101

p = 122.33

2 pointer = 2p - 66

2(122.33) - 66 = 178.67

1 point = 2p - 102

2(122.33) - 102

= 142.67

Note: you may need to recheck the parameters given, because the expected result should be whole numbers

Koto’s average velocity along her route was 4.5 m/s. She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west. What was the time of her trip? (There are 60 seconds in 1 minute.) 18.5 minutes 20.4 minutes 2 hours 3 hours

Answers

Answer:

18.5 minutes

Step-by-step explanation:

Koto’s average velocity along her route was 4.5 m/s.

She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west.

5000 meters west - 5000 meters east = 0

20,000 south - 15000 north = 5000 meters

4.5 meters = 1 second

5000 meters = x seconds

Cross Multiply

4.5 × x = 5000 × 1

x = 5000/4.5

x = 1111.11111111 seconds

There are 60 seconds in 1 minute.

60 seconds = 1 minute

1111.11111111 = y minutes

60 × y = 1111.11111111 × 1

y = 1111.11111111/60

y = 18.5185185185 minutes

Approximately = 18.5 minutes

The time of her trip is 18.5 minutes

Answer:

You purchase disposable plates, cups, and forks for a cookout. Plates are sold in packages of 24, cups in packages of 32, and forks in packages of 48. What are the least numbers of packages you should buy in order to have the same number of plates, cups, and forks?

Answers

Answer:

96 packages

Step-by-step explanation:

We solve for this question using Lowest Common Multiple (LCM) method

Step 1

We list multiples of each number until the first common multiple is found. This is referred to as the lowest common multiple.

From the question , we are told:

Plates are sold in packages of 24

Cups in packages of 32

Forks in packages of 48

Multiples of 24:

24, 48, 72, 96, 120, 144

Multiples of 32:

32, 64, 96, 128, 160

Multiples of 48:

48, 96, 144, 192

Therefore,

LCM(24, 32, 48) = 96

Hence, the least numbers of packages you should buy in order to have the same number of plates, cups, and forks is 96 packages

x=7.5

Total area = 27+15 = 42

Step-by-step explanation:

For question 13, we still need to find the bottom side of the T-shape that's not labeled. That's just 9-3.5-3.5=9-7=2.

Now that we know all the side lengths, we can set up an equation where all the side lengths add up to 39, and solve for x:

9+3+3+3.5+3.5+x+x+2=39

24+2x=39

2x=15

x=7.5

For question 14, we can divide the shape into 2 rectangles, which is shown in the picture attaches. Then, we just solve for each rectangle's area separately, and then add them up.

Rectangle A = 9*3=27

Rectangle B = 7.5*2=15

Total area = 27+15 = 42

What is the area of the square?

All the sides of a square are congruent. Let a be the side length of the square. Then the area of the square is the square of the side length of the square.

Then the area of the square will be

Area of the square = a² square units

A square has an area of 225 m².

Then the edge length of the square is given as,

a² = 225

a = 15 m

Then the length of the diagonal of the square will be given as,

⇒ a√2

⇒ 15 √2 m

The edge length of the square is 15 m. Then the length of the diagonal of the square will be 15√2 m.

A = 9 over 2 (b + 35)

Which of the following formulas correctly solves for the other base, b?

Answers

b - the other base;

A = 9/2 ( b + 35 )   / * 2  ( we will multiply both sides of the equation by 2 )

2 A = 9 ( b + 35 )

b + 35 = 2 A / 9  

b + 35 - 35 = 2 A / 9 - 35

Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+5−(5x+8)=−4x−7

3x+5+−1(5x+8)=−4x−7(Distribute the Negative Sign)

3x+5+−1(5x)+(−1)(8)=−4x−7

3x+5+−5x+−8=−4x−7

3x+5+−5x+−8=−4x+−7

(3x+−5x)+(5+−8)=−4x−7(Combine Like Terms)

−2x+−3=−4x−7

−2x−3=−4x−7

Step 2: Add 4x to both sides.

−2x−3+4x=−4x−7+4x

2x−3=−7

Step 3: Add 3 to both sides.

                      ANSWER  15x^2+116+192

Answer:

The chosen topic is not meant for use with this type of problem.

Step-by-step explanation:

The best way to try and solve is using the quadratic formula. The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√(b²-4ac))/(2a) . See examples of using the formula to solve a variety of equations.

( 5x + 12 ) x ( 3x + 16 )

Step one : use the distributive factor. To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

5x x 3x

5x x 16

12 x 3x

12 x 16

15x^2 + 80x + 36x + 192

Step two: Combine like terms

15x^2 + 116x + 192

Step three: Solve the equation for  x  by finding  a

,  b, and c of the quadratic then applying the quadratic formula.
