40) y=2x+1

42) y=-4/3x-2

Step-by-step explanation:

Answer:

Step-by-step explanation:

we call one side x and the other side 4x-7. Because in a rectangle opposite sides are equal we can now set up an equation.

x + x + 4x-7 +4x-7 = 180

              10x - 14 = 180

                   10x = 194

                    x = 19.4

the lenght of the other side is 4(19.4)-7 = 70.6

Step-by-step explanation:

Remember PEMDAS. This will help you a lot in algebra.

P Parenthesis

E Exponents

M Multiplication

D Division

A Addition

S Subtraction

This is the order of how all the operations should take place.

Note: Multiplication and Division happen together. Just go from left to right. This is the same for Addition and Subtraction.

Onto the problem!

First, look at PEMDAS.

P stands for Parenthesis so first we look for those.

In this case, we have a set here. Solve whatever is inside.

[tex]\frac{1}{2}*(4+8)[/tex]

[tex]\frac{1}{2}*(12)[/tex]

Next, look for Exponents. There aren't any in this expression, so we're okay to move on.

Now, look for Multiplication or Division.

[tex]\frac{1}{2}*(12)[/tex]

[tex]6[/tex]

The answer is 6.

I really hope this helped you! Asking for help is a great first step in math! Keep at it and I'm sure you'll succeed. :)

Answer:

in about 0.92 hours or 55.2 minutes

Step-by-step explanation:

The time they take to paint the room:

Pragnesh and Qazi  = 2 hours

Pragnesh and Ronghui = 3 hours

Qazi and Ronghui = 4 hours

Meaning, each hour (1)  they'll paint:

Pragnesh and Qazi  =  [tex]\frac{1}{2th}[/tex] of the room

Pragnesh and Ronghui = [tex]\frac{1}{3th}[/tex] of the room

Qazi and Ronghui = [tex]\frac{1}{4th}[/tex] of the room

By summing all their work abilities we can determine how long it would take if all three students worked together to paint the fence, which is:

[tex]\frac{1}{2} + \frac{1}{3} + \frac{1}{4} = \frac{13}{12th}[/tex] of the room each hour. Therefore the whole (1) room would be painted in 1 ÷ [tex]\frac{13}{12}[/tex] = [tex]\frac{12}{13} hours[/tex] or 0.92 hours or 55.2 minutes (0.92 * 60).

Answer:

Darius can buy 16 heads of cabbage

Step-by-step explanation:

28.80 divided by 1.80 is equal to 16.

[tex]y = - \frac{1}{2} x + 9[/tex]

since the slope-intercept equation is y=mx+b

m represents the slope

b represents the y-intercept

Answer:It would cost $11.70 for 2.25 pounds of gummy worms.

Step-by-step explanation:

$2.60*4=$10.40 for 2 pounds

$2.60/2=$1.30 for 1/4 of a pound which is equal to 0.25

$10.40+$1.30=$11.70 for 2.25 pounds of gummy worms

Answer:

It is C

You can either compare two similar points or just count the units on the graph

Answer:

Juan does not have enough lumber to make the five shelves.

Step-by-step explanation:

Let assume that:

If Juan bought a piece of lumber that is 18 feet long.

and the bookcase will have = 5 shelves

Also, the length of each bookcase = 2 1/2 long = 2.5 long

Then the amount required for the five shelves = 5 × 2.5

= 12.5 feet long

Therefore, we can say Juan does not have enough lumber to make the five shelves.

Hence, he will need an addition of: (18 - 12.5) feet = 5.5 feet piece of lumber

Answer:

c.

Step-by-step explanation:

when an equation doesn't have a y-intercept. That means it is proportional.

Answer:

-24 = 3x + 9

-24 - 9 = 3x

-33 = 3x

-33/3 = x

-11 = x

x = -11

Add 9 to both sides

So

-15=2x

Divide both sides by 2

So

X=-7.5

19 mph + 14 mph = 33 mph

198 miles / 33 mph = 6 hours

It will take them 6 hours to meet.

im pretty sure it's 6 hours

hopefully you get it right :)

Answer: 2 miles per hour

Step-by-step explanation:

Answer:

The wording of this question is vague.  Are the numbers 3.4, 2.2, and 4.6 the weights in pounds (lbs) of the individual items carried by each hiker?  I will assume that each of x hikers carries 3 items of weights 3.4, 2.2, and 4.6 lbs, and I will assume that you seek the total weight W carried by the group of x hikers.

W = (number of hikers)(pounds carried by each hiker) = x(3.4 + 2.2 + 4.6) lbs.

Answer:

I believe the answer is 3. AM = MB

Step-by-step explanation:

For the first option, 1/2 of AB is obviously equal to AM. Therefore, the second option is also correct.

As far as the fourth option, CD equals AB since a compass was used to gather the points, ensuring they are equidistance.

Answer:

n = 12

Step-by-step explanation:

Rewrite it as [tex]\frac{(n+3)}{5} = 3[/tex]

Multiply both sides by 5

(n+3) = 15

You can drop the parenthesis now.

n + 3 = 15

n = 12

Answer:

rotation

Step-by-step explanation:

The transformation used to transform figure 1 into figure 2 is a dilation.

A dilation is a transformation that yields a picture that differs in size while maintaining the original image's shape.

Given that, figure 1 is transformed into figure 2, and figure 2 is transformed into figure 3 which s similar to figure 1.

Since figure 1 is similar to figure 3, as per the transitivity property, figure 1 is similar to figure 2.

Since figure 1 is similar to figure 2, the ratio of their side lengths is proportional.

Since the ratio of the side lengths of the two figures is proportional, the transformation is a dilation.

Hence, the transformation used to transform figure 1 into figure 2 is a dilation.

Answer:

Step-by-step explanation:

In an equation, the additive property of equality states that if we add or subtract the same number to both sides of an equation, the sides remain equal.

transitive property,  If a = b and b = c, then a = c.

Segment Addition Postulate Defined. The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.
