A soccer player gets 2 points for a goal and 1 point for an assist. If the combined number of goals and assists that a player ha

s is 24, and the total number of points that the player has is 42, which system of equations can be used to determine the number of goals and assists the player has? Assume g represents the number of goals and a represents the number of assists. G a = 24. G 2 a = 42. G a = 24. 2 g a = 42. G a = 42. G 2 a = 24. G a = 42. 2 g a = 24.

The player has a total of 18 goals scored and 6 assists made.

<h3>Equation</h3>

Equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of goals scored and y represent the number of assists. Since the combined goals and assist is 24, hence:

x + y = 24     (1)

Also:

2x + y = 42    (2)

From equation 1 and 2:

x = 18, y = 6

The player has a total of 18 goals scored and 6 assists made.

What is the volume of the triangular prism? A triangular prism. The base of the triangular face is 5.4 centimeters and the heigh
IceJOKER [234]

Answer:

The volume of the triangular prism is <em>51</em><em>.</em><em>84</em><em> </em><em>cm</em><em>^</em><em>3</em>.

Step-by-step explanation:

The formula of the volume of a prism is:

V = Ah

where:

V = Volume of prism

A = Area of uniform cross-section or base of prism

h = Height of prism = 6 cm

We can substitute the information given in the problem into this formula.

To find A, we need to find the area of the triangular base.

A = bh / 2

where:

b = Base of triangle = 5.4 cm

h = Perpendicular height of triangle = 3.2 cm

We can substitute the information given in the problem into this formula.

A = ( 5.4 × 3.2 ) / 2

A = 17.28 / 2

A = 8.64 cm^2

Substitute the value of A into the original volume of a prism formula with the other information given in the problem.

V = Ah

V = ( 8.64 ) ( 6 )

V = 51.84 cm^3

List the markup and retail price of each item. Round to two decimal places when necessary. A shirt item price is $33.75 and the
kifflom [539]

Answer:

markup price = $25.31

retail price = $59.06

Step-by-step explanation:

Markup price is 75% OF 33.75

Retail price is original price (33.75) PLUS the markup price (to be found)

Firstly, converting a percentage to a decimal is simple. We simply divide by 100. So:

75% = 75/100 = 0.75

Now, to find markup, we multiply:

33.75 * 0.75 = $25.31

Now, the retail price is SUM of original and markup, that would be:

retail price = 33.75 + 25.31 = $59.06

Thus,

markup price = $25.31

retail price = $59.06

Can anybody tell me why it’s “-275”? Why is it negative ? And what is the formula for finding y? And if y=b how do you find b?
Norma-Jean [14]

Answer:

275 is the amount SPENT per month for rent. Since you are decreasing that amount from your savings, it is represented with a negative sign.

The formula is: y = mx + b      where

  • m is the rate             -->   -275 per month
  • b is the fixed rate     --> 3500 savings

If you think about it logically - You have 3500 and spend $275 per month

1st month: 3500 - 275 = 3225

2nd month: 3225 - 275 = 2950

3rd month: 2950 - 275 = 2675

4th month: 2675 - 275 = 2400

5th month: 2400 - 275 = 2125

6th month: 2125 - 275 = 1850

It is easier to write it as an equation where x is the number of months and y is the balance for that month.

y = -275x + 3500

To check if the point (6, 1850) is on the line, input x = 6 and y = 1850

     y = -275x   +  3500

1850 = -275(6) + 3500

1850 =  -1650  + 3500

1850 =        1850

Since it makes a true statement, (6, 1850) is a point on the line.
