At a sale, you purchased a $20 scarf for $15. What
was the percent of change?

Answer:

multiple o.45 by 75 the answer is the answer to the problem

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

we distribute the 3 and 2 on both sides to get:

3x+3=2x-2

we can subtract 3 on both sides to get

3x=2x-5

Now we subtract 2x on both sides to get

x=-5

Hope this helps :)

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

Explanation:

The order of the letters is very important. This is because the order tells us how the angles pair up and that leads to telling us how the sides correspond to one another.

Note with ABC and FGH, the first and last letters are AC and FH respectively. These sides correspond. We're told that FH is 1/3 as long as AC when your teacher wrote FH = (1/3)*AC; we can solve for AC to get AC = 3*FH.

Going back to ABC and FGH, we see that the first two letters of each are AB and FG. This is another pair of corresponding sides. We're told that 3*FG = AB. So AB is three times longer than FG.

So far we can see that

The missing information we need is that BC = 3*GH. If we know this, then we can use the SSS similarity theorem to prove the triangles are similar. Note how BC are the two last letters of ABC while GH are the last two letters of FGH.

Starting with BC = 3*GH, we can divide both sides by GH and we get BC/GH = 3.

[tex]y = 22[/tex]

Multiply both sides by y × 11

[tex]3y = 6 \times 11[/tex]

Solve a solution to y

[tex]y = 22[/tex]

Answer:

x = -3

Step-by-step explanation:

55 + 54 = 109

109 + 74 = 183

Triangles = 180 degrees

So, 74 - 3 = 71

And 55+54+71 = 180

Answer: 2592

Step-by-step explanation:

Answer:

2592

Step-by-step explanation:

Im going to separate this to a square and a rectangle

36*36=1296

72*18= 1296

so 1296+1296=2592

thus the answer is 2592

good luck

Answer:

The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Step-by-step explanation:

To find: What is the constant term in the polynomial expression, and what does it represent?

The given expression is [tex]-8x^2 + 54x + 140[/tex].

To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.

=[tex]-8(0)^2 + 54(0) + 140[/tex]

=[tex]140[/tex]

The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.

Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Answer:

x = 3w + 25m

Step-by-step explanation:

The number of dogs she walks (w) and the number of lawns that Sammy mows (m) need to be multiplied by the amount of money that Sammy makes from each individual action. Both of these products are then added together to equal the total amount of money that Sammy has earned. All of this can be represented with the following expression where x is the total amount of money earned...

x = 3w + 25m

Answer:

[tex]187.74\:\mathrm{cm}[/tex]

Step-by-step explanation:

The area of a rectangle is given by [tex]l\cdot w[/tex]. Therefore, we can set up the following inequality:

[tex]l\cdot 16 \leq 3,003.84[/tex].

Solving this inequality, we have:

[tex]l \leq 187.74[/tex].

Therefore, the largest length Carmen's painting can be is [tex]\fbox{$187.74\:\mathrm{cm}$}[/tex].

Answer:

the first one, 5(x-4) + 29

Step-by-step explanation:

Answer:

The solution for x would be 4.

Step-by-step explanation:

2x - 1 = 7

The value of x is unknown, but you do know that you are multiplying 2 by x. So, if you rewrite the equation as 7+1=2x, you know that 8=2x. If you then divide both sides by 2, you're left with 4=x which would mean that the variable x has a solution of 4

Answer:

All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Step-by-step explanation:

Answer:

Step-by-step explanation:

slope in an equation is the number before the x

in a table it is y2-y1/x2-x1

Answer:

33/3  

55/5

77/7

When these are simplified, they are equal to 11/1

Answer:

There is no slope

Step-by-step explanation:

There is no slope bc the entered points belong to a vertical line

the equation: x = -3

Answer: 8 + 3/4W

Step-by-step explanation:

From the question, we are informed that Leah is training for a bike race she start by biking 8 miles during every training session and that each week she plans to increase the distance of her training session by 3/4 mile W the number of weeks.

The expression to show the distance Leah bikes in a training session after W weeks will be:

= 8 + 3/4W

For example, after 4 weeks, the distance biked will be:

= 8 + 3/4W

= 8 + (3/4 × 4)

= 8 + 3

= 11 miles
