91 is 70% of what number?91 is 70% of what number?

Answer:

there were 4 small boxes sent and 7 large boxes sent

Step-by-step explanation:

let s= number of small boxes

let y= number of small boxes

each small box can hold 25 books, so s small boxes can hold 25s books. Each large box can hold 50 books, so l large boxes can hold 50lbooks. Therefore, the total number of books 25s+50l equals 450.

Since there were 3 more large boxes sent than small boxes, if we add 3 to the number of small boxes, we will get the number of large boxes, meaning l equals s+3.

system of equations:

25s+50l=450

l=s+3

substitute values

Answer:

1

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(-3 + 12) / (15 - 6)

9 / 9

= 1

So, the slope is 1

Answer:

[tex]\frac{9}{20}[/tex] [tex]miles^{2}[/tex]

Step-by-step explanation:

To find the area of a rectangle, use the formula A = l*w, where l is the length and w is the width.

A = [tex]\frac{9}{10}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{9}{20}[/tex] [tex]miles^{2}[/tex]

hope it is right answer for it!!

Answer:

Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.

The cost of 4 hamburguers can be represented with this expression:

4x4x

And the cost of 6 soft drinks  can be represented with this expression:

6y6y

Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:

4x+6y=344x+6y=34   [Equation 1]

 The following expression represents the the cost of 3 soft drinks:

3y3y

According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:

4x+3y=254x+3y=25 [Equation 2]

Therefore, the Equation 1 and the Equation 2 can be used to determine the price of a hamburger and the price of a soft drink

Answer:

3x + 6y = 27

3x + 3y = 18

x = $3, y = $3

Step-by-step explanation:

I will solve by using the elimination method.

3x + 6y = 27

3x + 3y = 18

Subtract top equation by bottom.

3x + 6y = 27

- (3x + 3y = 18)

_____________

  0 +  3y  =  9

3y = 9

y = 3

Plug y in for three

3x + 6*3 = 27

3x + 18 = 27

3x = 9

x = 3

So, your solution is x = $3, y = $3

Answer:

No Solution.

Step-by-step explanation:

12(x-3)+18=4(3x-3)

12x-36+18=12x-12

12x-12x-18=-12

-18=-12

no solution

Answer:

1.1(x+2) = 1.1x + 2.2

Step-by-step explanation:

I) Distribute the terms using the Distributive Property:

1.1(x+2)

= 1.1(x) + 1.1(2)

II) Simplify:

1.1(x) + 1.1(2)

= 1.1x + 2.2

7a - 4b

Step-by-step explanation:

Add the numbers ending with 'a' together, and then add the numbers ending with 'b' together.

First of all, I will put the letters beside each other.

2a + 5a + 3b - 7b

2a + 5a = 7a

3b - 7b = - 4b

Therefore, the answer is 7a - 4b.

Answer: The selling price will be $1.68  

Step-by-step explanation:

If the magazine is marked-up by 12% , then you will multiply 12% by the amount of money then add it to the same amount of money.

1.50 * 12% = 0.18

1.50 + 0.18 = 1.68

Answer:

The medium - 6,6

The mean - 5.1 or 5

Step-by-step explanation:

The medium is the middle number(s)

The mean is when you average the numbers (adding them all up then dividing by how many numbers there are).

Answer: before u do all of this put the number in smallest to biggest the mean is u add all the number then when u get the answer u divide the number by how many numbers are there so 2 + 3+3+4+5+6+6+6+7+9= 51 now 15 divided by 10 =5.1 that is the mean

Now the medium is u put the number in smallest to biggest again 2334566679 now u have to find the numbers that are the same so u see how there is two 3's and three 6's in the numbers right so u have to look very carefully u could put 3 has the answer put that is not the answer because there is only two 3's and there is three 6's so which is bigger two 3's or three 6's three 6's is bigger so that is the answer.

Step-by-step explanation:

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

Work Shown:

The diagram shows that JK = 12 and GF = 2.5*(JK) = 2.5*12 = 30

The midsegment HL will be the average of the two lengths it is parallel to.

We'll add up the values and then cut the result in half

HL = (JK+GF)/2

HL = (12+30)/2

HL = 42/2

HL = 21
