5x + 3y = 41
2x + 3y = 20
show me step by steps how to do this

Answers

Answer 1
Answer:

The answers are:

x = 7y = 2Step-by-step explanation:

5x + 3y = 41

2x + 3y = 20

=> 5x + 3y = 41

           -2x - 3y = -20

=> 3x = 21=> x = 7

=> 5(7) + 3y = 41

=> 35 + 3y = 41

=> 3y = 41 - 35

=> 3y = 6

=> y = 2

Conclusion:

Therefore, the answers are:

x = 7y = 2

Answer 2

Answer:

Step-by-step explanation:

It looks like you need to solve this system of equations.

That means we need to find a value for x and a value for y that makes both equations true.

Since both equations have a 3y in them, this system is ready to use a method called "elimination method"

Since the x terms are lined up, and the y terms are lined up, the equal signs are lined up, and the constants are lined up...you can subtract the bottom equation from the top equation.

5x + 3y = 41

2x + 3y = 20

Subtract and you will get

3x + 0y =21

We don't need to write that 0y, because it is 0.

3x = 21, now divide by 3

x = 7, almost finished!

Use x = 7 in either of the original equations to find y.

5x + 3y = 41 and x = 7

5•7+ 3y = 41

35 + 3y = 41

-35 -35

3y =6

y = 2

So the solution is x=7 and y=2

That can also be written as an ordered pair (7, 2)

Answers

Step-by-step explanation:

when a line cuts through 2 parallel lines, it does the exact same thing to both lines. it has to. because they are parallel, they act as if they are identical. only their placement is different, but this has no impact on the angles between the lines.

now, imagine a circle with the center at one of the crossing points. this circle is cut in half by the central line.

you know how many degrees a full circle has ?

360 degrees.

now, how many degrees are represented by the half- circle above or below the center line ?

of course, half of the degrees of the full circle. that means 180 degrees.

so, all the angles around a single point on one side of a line must have how many degrees together ?

right, these half-circle 180 degrees again.

because of everything we said up there, the angle 4x+6 is the same as the angle right of the 7x-2 angle.

so, 7x-2 and 4x+6 must be 180 degrees together.

that is called "supplementary angles".

7x - 2 + 4x + 6 = 180

11x = 176

x = 16

Anita plans to give her husband 3 shirts for his birthday. She narrows the search to 3 shirts from a selection of 17 shirts at Dillon's Store or 3 from a selection of 20 shirts at The Men's Shop. In how many ways can she select the shirts

Answers

Using the combination formula, it is found that she can select the shirts in 775,200 ways.

The order in which the shirt are chosen is not important, hence, the combination formula is used to solve this question.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem:

3 shirts from a set of 17.Then, 3 shirts from a set of 20.They are independent, hence, to find the total, we multiply both combinations.

[tex]T = C_{17,3} \times C_{20,3} = \frac{17!}{3!14!} \times \frac{20!}{3!17!} = 680 \times 1140 = 775200[/tex]

She can select the shirts in 775,200 ways.

Clara is making a pennant. She attaches a rectangle that is 1 inch wide and 6 inches long to a triangle that has a base of 6 inches and a height of 28 inches. What is the area of the
pennant?

Answers

The area of the pennant made by Clara is 90 in²

Area

Area is the amount of space taken up by a two dimensional figure. It measures the quantity of space covered by the figure.

Area of the rectangle = length * width = 6 in * 1 in = 6 in²

Area of triangle = (1/2) * base * height = (1/2) * 6 in * 28 in = 84 in²

Area of the pennant = 6 in² + 84 in² = 90 in²

A salesperson rent a car for a work trip. The rental car company charges the salesperson $25 each day and a flat fee of $100 for insurance.
If the salesperson is charged a total of $225 to rent the car for 2 days, which statement is true?
The equation 25% + 100 = 225 can be used to find 2, and the salesperson rents the car for exactly 2 days.
The equation 252 + 100 = 225 can be used to find z, and the salesperson rents the car for exactly 5 days.
The equation 100:1 + 25 = 225 can be used to find 2, and the salesperson rents the car for exactly 2 days.
O The equation 100.0 + 25
225 can be used to find, and the salesperson rents the car for exactly 5 days.

Answers

The true statement will be "the equation 25z + 100 = 225 can be used to find z, and the salesperson rents the car for exactly 5 days.

Let the number of days used to rent the car be z

If the rental car company charges the salesperson $25 each day, the total charges for "z" days will be $25z

If a flat fee of $100 for insurance is added and the salesperson is charged a total of $225 for "z" days, hence the required equation that represents this statement is expressed as:

Rental charges for "z" days  + $100 = total charge25z + 100 = 225

The true statement will be "the equation 25z + 100 = 225 can be used to find z, and the salesperson rents the car for exactly 5 days.
