Pleaseeeee I beg of you I’ll give brianliest i don’t understand.

Answers

Answer 1

Answer:

x=15

m<ABC=30

m<BCA=60

m<CAB=90

Step-by-step explanation:

to find the value of x I used the 5x+15 since we know that is a right angle. so we equal 5x+15 to 90. you subtract 15 to both sides and then get 5x=75 and then divide by 5 to both sides to get x=15. you the plug in the 15 to the other parts, so 2x=2(15)=30 and 4x=4(15)=60

Answer 2

Answer:

x=15

m<ABC=30

m<BCA=60

m<CAB=90

6. Julie is asked to solve the system below by elimination. Which of the following steps
would be the best way to begin?
2x + y = -3 ?
3x - 2y = 2

A. Multiply O by 2 and multiply by 3
B. Multiply by 2
C. Multiply O by 2
D. Multiply by 2 and multiply O by -2

Answers

Answer: A

Step-by-step explanation:

The best way to solve the system below by elimination is to multiply

2x + y = -3 by 2.

What is elimination method?

The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

According to the question

Equations given

2x + y = -3 -------------------------- (1)

3x - 2y = 2 --------------------------(2)

Now, solving by applying elimination method

Case 1: solving for y , eliminate x

Multiplying equation (1) by 3 and equation (2 ) by 2

6x + 3y = -9

6x - 4y = 4

now subtracting both we will get value of y then we can get x by substituting y in equation

Case 2:

solving for x , eliminating y

Multiply equation (1) by 2

4x + 2y = -6 ---------------------------- (3)

3x - 2y = 2 --------------------------(2)

now, adding both equation will give x value then we can get y by substituting x in equation

Hence, Multiply equation (1) by 2 will be best way .

A ballroom has a square dance floor. The area of the floor is 400 square feet. Of the length of each side of the square increased by one foot, would its area be a rational number? Explain.

Answers

Answer:

It is given in the question that

A ballroom has a square dance floor. The area of the floor is 400 square feet.

And the formula of the area of the square sides square.

So we will get

400= side^2

Taking square root on both sides,

side=20

And on increasing the side length by one foot, we will get the side length of 21 feet.

And it is not a perfect square.

And the area is

Area= 21^2 = 441ft^2

And 441 is a perfect square and a rational number.

Therefore true statements are A and E.

Step-by-step explanation:

^ means squared

statements A and E are correct
