Answer:  Create equations. Top length=Bottom length

Left side = right side.

Combine like terms and rewrite the equations.  

Use the new equations to create a system of equations to solve for x and y.

Once you have x and y, you can substitute those in the expressions for the lengths of the parallelogram.

You should end up with top and bottom lengths of 10. The sides are 9.

Step-by-step explanation:

3x-5 = 18 -2y . Rewrite as 3x + 2y = 23

x+4 = 21 -3y    Rewrite as  x + 3y = 17

The system of equations is

3x + 2y = 23   and  x + 3y = 17 . To solve by substitution, multiply the second equation by -3   It becomes  -3x-9y= -51  Add the equations so the x terms cancel. Solve for y

3x + 2y = 23

-3x - 9y = -51

0  -7y  = - 28  Divide both sides by -7.   y = 4

Substitute 4 for y,  solve for x

x + 3(4) = 17

x + 12 = 17 . Subtract 12 from both sides   x = 5

Substitute the values of x and y in the expressions

Top: 3x-5    is 3(5) -5  becomes 10

Bottom: 18 -2y  is  18 - 2(4) becomes 10

Left:  x +4   is (5) + 4  becomes 9

Right:  21 - 3y  is  12 -3(4)  becomes 9

Answer:

1. 2.19g + 0.59b + 1.49p

2. 6.57 + 1.77 + 2.98 = 11.32

Answer:

Part A.)   2.19g + 0.59b + 1.49p

Part B.)   11.32

Step-by-step explanation:

Part A.)  

basically they give you the price for each item in the upper description. Just use g,b,p in terms that they gave you

Part B.)

plug in the amount of fruit per pound for each matching variable

2.19(3) + 0.59(3) + 1.49(2) = 11.32

Answer:

y=-1x+2

or

y=-x+2

y=mx+b

Answer:

11.2

Step-by-step explanation:

56 divided by 5

Answer:

21

Step-by-step explanation:

6(y^2) - 24y -51 = 6 4 - 24y - 51

(6 4) - (24y) - 51 = 24 - -48 - 51

(24 - -48) - 51 = 72 - 51

72 - 51 = 21

Answer:

$112

Step-by-step explanation:

So first figure out how much he makes an hour

8*4 is 32.

32*3 1/2 is $112

The amount that Chris will make will then be $112.

The first thing to do is to divide 3 1/2 by 1/4. This will be:

= 3 1/2 / 1/4

= 7/2 × 4/1

= 14

Now we'll then multiply 14 by $8. This will be:

= $8 × 14

= $112

The amount made will be $112.

-28 + 8 =

-20

An expression equivalent to 4(– 7) + 8 would be:

8 + 4(-7)

This is true because of the commutative property which states that a+b=b+a

Answer:

The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case, we are given

The slope m = -1/2

Point (2, -3)

now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept

[tex]y = mx+b[/tex]

-3 = -1/2(2) + b

-3 = -1 + b

b = -3 + 1

b = -2

now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation

y = mx + b

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

y = -1/2x - 2

Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

the answer is:

10z+6

Answer:

4

Step-by-step explanation:

We are asked to find a slope whilst given a graph.

To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.

So based on what I see, I can see (1, 1) and (2, 5).

The rise over run is as followed :

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

2 and 1 meaning the first and second number within the coordinate, so substitute :

[tex]\frac{5 - 1}{2 - 1}[/tex]

[tex]\frac{4}{1}[/tex]

Divide :

[tex]4[/tex]

4 is our slope.
