I'm confused about this, can someone answer?

Answer:

[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]

Step-by-step explanation:

2x + 3y = 12

5x - 2y = 11

2x + 3y + 5x - 2y = 11 + 12

7x + y = 23

[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]

Answer:

x=40

Step-by-step explanation:

you have to get a answer of 60

(40)+20=60

and 2(40)-20=60

I think the answer should be b, since y=3 when x=0, according to the option B.

y = x + 3, B

Answer: m<8 = 58 degrees

m<5 = 122 degrees

Answer:

12.56

Step-by-step explanation:

the equation for a circumference is C=2pi r

C=2*3.14*2

2*3.14=6.28

6.28*2=12.56

Answer:

55 centimeters

Step-by-step explanation:

It is a right triangle which means it will add up to 90 degrees. You would start by adding 20 and 15 which is 35 and then subtract 35 from 90 to get 55. I hope this helped :)

Answer:

5A)36 5b)30(mark as brainliest)

Step-by-step explanation:

5a)6+6+6+6+12 = 36

5b)36-8=28

28+2 = 30

Answer:

a: The answer is 36 units squared

b: You would lose four square units

Step-by-step explanation:

a: You can count the pieces showing, but you also have to add the amount you cannot see, which would give you a total of 36 units squared (since it doesn't say what each unit is represented by

b: The bottom pieces that originally were not showing would now be showing, but you would lose the ones above it. These cancel out from each other. There are 4 other sides that are now no longer showing since the others that are still showing still were anyways, so there are 4 units squared missing from the surface area when you remove the top two blocks.

Answer

y = 0.2x − 7

Step-by-step explanation:

Find the slope first by subtracting (10, -5) and (5, -6) in slope formula, this will equal 1/5 or 0.2

Then find the y-intercept which is the point that crosses the y-axis, in this case -7 is the y-intercept

Finally format in y=mx + b for slope-intercept form

y=0.2x-7

Answer:

what is the question?????????????

Answer:

9:30am

Step-by-step explanation:

To find what time simply add all of the minutes together and subtract. All of the steps take 100 minutes to do. 11.10 am is 670 minutes. So 670 - 100 = 570 then divide by 60 to get the time ie 9:30 am

A. The area is 4 square units

B. The description is below

======================================================

Break the figure into two parts along the dashed line. So we get a triangle on the left and a rectangle on the right.

The triangle has horizontal base of 3-1 = 2, and height 2. It's area is base*height/2 = 2*2/2 = 4/2 = 2 square units.

The rectangle is 1 by 2, so it's area is length*width = 1*2 = 2 square units.

Combine the two smaller areas to get the overall area: 2+2 = 4 square units

--------

As an alternative, you can use the trapezoid area formula

b1 = 3 and b2 = 1 are the two parallel bases

h = 2 is the height

A = area of trapezoid

A = h*(b1+b2)/2

A = 2*(3+1)/2

A = 2*4/2

A = 8/2

A = 4 square units

Answer:V=804.3

Step-by-step explanation:

Answer:

804.25

Step-by-step explanation:

Formula=V=πr^2 h/3

V=π8^2 12/3

Answer:

it's either a or b, but I would go with A

Answer:

the correct answer is A because the synonym 0f supplementary angle is straight angle and on obviously the sum of straight angle is 180⁰.

Answer:

Step 1

Step-by-step explanation:

They're all wrong expansions but step 1 was where he made his first error... He shifted the bracket putting 3x inside the bracket... While the other steps the first expansion of 3x eliminating the bracket was correct.

The correct expansion is meant to be 3x + 21 + 5 = 3x + 26

Answer:

Number of juice boxes people drank at Williams party = 91

Step-by-step explanation:

Total juice boxes Williams bought = 114

Juice boxes left over at the party = 23

How many juice boxes did people drink at William's party?

Number of juice boxes people drank at Williams party = Total juice boxes Williams bought - Juice boxes left over at the party

= 114 - 23

= 91

Number of juice boxes people drank at Williams party = 91

Answer:

3

Step-by-step explanation:

Answer:

Step-by-step explanation:

1. Equation

3x + 4 = 25

2. Subtract 4 from both sides

3x + 4 = 25

     - 4    - 4

3. Solve

3x = 21

4. Divide both sides by 3

3x = 21

/3     /3

5. Solve

x = 7
