A prom dress is on sale for $350. If the original price of the dress was $500, what percent of discount was used during the sale?

The length of the drawing on the map for 36 miles is given by the equation A = 4 1/2 inches

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number of miles be = 12 miles

So , 12 miles on the drawing represents = 1 1/2 inches

Now , the number of miles = 36 miles

12 x 3 = 36 miles

And , 36 miles on the drawing represents = 3 x 12 miles on the drawing

Substituting the values in the equation , we get

36 miles on the drawing represents A = 3 x ( 1 1/2 )

On simplifying the equation , we get

36 miles on the drawing represents A = 4 1/2 inches

Hence , the value on the drawing is 4 1/2 inches

Answer:

41

Step-by-step explanation:

Since a triangle is 180 degrees ans the triangle is on the right is equal to the triangle on the left, all you have to do is take 180 and subtract 86 and 53 from it to get 41. There's also the fact that the length of all the sides are the same so that can also mean that the angles are the same.

Answer:

{5, 6, 7, 8, 9, 10}

Step-by-step explanation:

Given the inequality

5m - 7 > 16

Add 7 to both sides

5m-7+7>16+7

5m>23

Divide both sides by 5

5m/5>23/5

m>4.6

Hence the value of m are the values in the set greater than 4.6 and they are {5, 6, 7, 8, 9, 10}

Answer: Only j = 2

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

Explanation:

Let's solve for j

[tex]\frac{96}{j} \ge 40\\\\96 \ge 40j\\\\\frac{96}{40} \ge j\\\\2.4 \ge j\\\\j \le 2.4[/tex]

In the second step, I multiplied both sides by j. If j is a positive number, then the inequality sign will not flip. All of the answer choices are positive numbers, so we don't have to worry about the inequality sign flipping.

The last step shows that j = 2.4 or j < 2.4

So j is 2.4 or smaller.

Of the list given to us, only j = 2 fits the description, since something like j = 8 is not 2.4 or smaller.

---------------------------

If j = 2, then,

[tex]\frac{96}{j} \ge 40\\\\\frac{96}{2} \ge 40\\\\48 \ge 40\\\\[/tex]

which is a true statement since 48 is larger than 40. This shows that j = 2 is a solution.

Something like j = 8 does not work because

[tex]\frac{96}{j} \ge 40\\\\\frac{96}{8} \ge 40\\\\12 \ge 40\\\\[/tex]

which is false because 12 is not equal to 40 or larger than 40. This means j = 8 is not a solution. You should find that j = 12 and j = 3 lead to similar false statements.

Of the list given, j = 2 is the only solution.

So this is False.

So this is False.

Step-by-step explanation:

Answer: x = -1 and y = -2

Step-by-step explanation:

You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:

6x + 5(7x + 5) = -16

I replaced y in the first one in terms of x, so that we can solve just for x.

6x + 35x + 25 = -16

41x +25 = -16

41x = -41

x = -1

Now simply find y by plugging the now known x value into either equation

y = 7(-1) + 5

y = -2

Answer:

x = -1

y = -2

(  -1, -2 )

Step-by-step explanation:

6x + 5y = -16

They gave us what "y" is and its....

y = 7x + 5

We substitute the "y" in the equation with this "y = 7x + 5

"

6x + 5y = -16

6x + 5(7x + 5) = -16

Now we need to use the distributive property (multiply what is in the parenthesis by "5")

6x + 5 * 7x + 5 * 5 = -16

6x + 35x + 25 = -16

Combine Like Terms ( 6x and 35x)

41x + 35 = -16

Subtract 25 on both sides

41x + 35 - 25 = -16 - 25

41x = -41

Divide by 41 on both sides to isolate the variable

41x/41 = -41/41

x = -1

Now that we have what "x" is (-1) we can use that to find out what "y" is.

y = 7x + 5

Substitute the x with -1

y = 7x + 5

y = 7(-1) + 5

y = -7 + 5

y = -2

x = -1

y = -2

( x, y )

( -1, -2 )

Answer:

[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(-0.75x-7\right)-\left(7.5x+5.4\right)[/tex]

Remove parentheses:   (-a) = -a

[tex]=-0.75x-7-\left(7.5x+5.4\right)[/tex]

As we know that:  - (7.5x + 5.4) = -7.5 - 5.4

[tex]=-0.75x-7-7.5x-5.4[/tex]

Group like terms

[tex]=-0.75x-7.5x-7-5.4[/tex]

Add similar elements:  -0.75x - 7.5x = -8.25x

[tex]=-8.25x-7-5.4[/tex]

Subtract the numbers:  -7 - 5.4 = -12.4

[tex]=-8.25x-12.4[/tex]

Therefore, we conclude that:

[tex]-0.75x-7-7.5x-5.4=-8.25x-12.4[/tex]
