Answer:

Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0  

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12:     x= [tex]\frac{-6 + y}{2}[/tex]

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

Answer:

The representation of Brian's situation in slope intercept form is:

                              y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                         y= 45+25+ 15 x

                   or, y= 15 x +70

which is in the form of,

                              y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

c= constant.

Answer:

We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km.

Since it takes Angel 2 minutes to run 1 lap, she will take

2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.

So it takes Angel 5 minutes to run 1 km.

Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden

2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.

So it takes Jayden 416 minutes to run 1 km.

i actually dont know what the answer-answer is but i think this will help alot.

Answer:

Step-by-step explanation:

Distance traveled in 2 minutes by Angel = 2/5 kilo meter

Distance traveled in 1 minute by Angel = [tex]\frac{2}{5}[/tex] ÷ 2

                                                                 [tex]=\frac{2}{5}*\frac{1}{2}[/tex]

                                                                 = 1/5 kilometer

Answer:

The total volume of water in the pool  = ( 6x^3 + 12x^2 - 90x ) ft^3

Step-by-step explanation:

The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3

The volume of water in the shallow     =  (4x^3 -100x) ft^3

The total volume of water in the pool  = (2x^3 + 12x2 + 10x)  +  4x^3 -100x)

                                                              = ( 6x^3 + 12x^2 - 90x ) ft^3

plz can i get brainliest:)

The way the question is worded is a little confusing.

I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)

The length of the rectangle will be 10 m.

A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.

Given that, a rectangle has sides that are 10 m, 10 m, 5 m, and 5 m.

We need to find the length of the rectangle,

We have the dimensions 5 m x 10 m,

Lengths in a rectangle tells that how much the rectangle is long and the width tells how much the width tells about the breadth of the rectangle,

So, we can say that,

Length = 10 m

Width = 5 m

Hence, the length of the rectangle is 10 m.

Answer:

The median is 7.

Step-by-step explanation:

In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).

I'm gonna do both as an example.

Greatest to least:

14, 13, 9, 9, 7, 5, 3, 2, 1

Least to greatest:

1, 2, 3, 5, 7, 9, 9, 13, 14

It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.

The next thing you need to do is find the number that is in the middle.

It will be the same for both least to greatest AND greatest to least.

You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.

In this case, your answer goes like this:

since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.

In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.

I hope this helped you!

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate

AB = 13 - 2 = 11 units

As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate

CD = 13 - 2 = 11 units

As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate

BC = 15 - 12 = 3 units

As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate

AD = 15- 12 = 3 units

AB = CD = 11 units

BC = AD = 3 units

So,ABCD is a rectangle

Area = 11 * 3 = 33 square units

Perimeter = 11+11+3+3 = 28 units

Answer:

At first

Length of AB = 13 - 2 = 11 cm

Length of CD = 13 - 2 = 11 cm

Length of BC = 15 - 12 = 3 cm

Length of AD = 15 - 12 = 3 cm

Now

Perimeter = 11 + 11 + 3 + 3

Perimeter = 22 + 6

Perimeter = 28

Area = 11 × 33 = 33 cm

Answer: 84.8 I’m sorry if this does’nt help

Step-by-step explanation:

Answer:

1: Tip, $2.23

2: Tax, $0.74

3: Total, $17.87

4: Split, $5.95

Step-by-step explanation:

To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.

To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.
