Answer:

Sale price of backpack is $19.5

Step-by-step explanation:

Original price of backpack = $26

Discount = 25%

We need to find sale price.

First we will find amount that will be discounted, and then subtract from original price.

So, Finding discount price

[tex]25\%of 26\\=\frac{25}{100}\times 26\\=6.5[/tex]

So, there will be discount of $6.5

Now, the sale price will be:

Sale price = Original Price - Discount

Sale Price = 26 - 6.5

Sale Price = 19.5

So, Sale price of backpack is $19.5

Answer:

30 yellow roses

Step-by-step explanation:

4:6 means that there are 10 parts all together

divide the total number of roses by the amount of parts.

50 divided by 10 is 5.

to find out red roses, do 5 times 4,

to find out yellow roses, do 5 times 6

Answer:

if a z-score is equal to +1, it is 1 standard deviation above the mean.

Step-by-step explanation:

Answer:

x is equal to negative one, and y is equal to negative four.

Step-by-step explanation:

You can do this by solving one of the equations by either x or y, then substituting it into the other.  Let's solve the second one for y:

[tex]2y = 3x - 5\\y = \frac{3x - 5}{2}[/tex]

Now we'll substitute that into the first equation:

[tex]9x - 2y = -1\\9x - 2(\frac{3x - 5}{2}) = -1\\9x - 3x + 5 = -1\\6x + 5 = -1\\6x = -6\\x = -1[/tex]

So we now know that x is equal to -1.  We can simply substitute that into one of the original equations to find y:

[tex]2y = 3x - 5\\2y = 3(-1) - 5\\2y = -3 - 5\\2y = -8\\y = -4[/tex]

We now know that x is equal to -1, and y is equal to -4.  We can also check our answer by plugging that -4 into the other equation, and see if we still get -1:

[tex]9x - 2y = -1\\9x - 2(-4) = -1\\9x + 8 = -1\\9x = -1 - 8\\9x = -9\\x = -1[/tex]

So we know that our answer is correct.

-5x + y = 7

x+3y = 5

Step-by-step explanation:

when you graph the equations, they are parallel. as you know, solutions are the point where the lines meet. if they are parallel, it's not possible for the lines to intersect.

Answer and Step-by-step explanation:

Lets solve each one and see which has solutions and which one doesn't have a solution.

__________________________________________________________

A) x + y = -6

   x + y = 12

Solve for y for one of the equations, then plug it into the other equation.

y = -6 - x                  

x + (-6 - x) = 12     =    -6 = 12  No Solution

__________________________________________________________

B) y = 2x + 5

   y = -3x + 1

2x + 5 = -3x + 1

4 = - 5x

[tex]-\frac{4}{5} =x[/tex] Solution

_________________________________________________________ C) y = 4x - 8

    y = 2x - 4

4x - 8 = 2x - 4

2x = 4

x = 2 Solution

__________________________________________________________

D) -5x + y = 7

     x + 3y = 5

x = 5 - 3y

-5(5 - 3y) + y = 7

-25 + 15y + y = 7

16y = 32

y = 2 Solution

__________________________________________________________

So, A is the correct answer. Sorry for the late answer!

Answer:

35

Step-by-step explanation:

2x = 2 times 4.5

    = 9

5y = 5 times 5.2

    = 26

2x + 5y is 9 + 26

= 35

35

Steps

2x + 5y

x = 4.5

y = 5.2

a. Substitute

2(4.5) + 5(5.2)

b. Multiply

9 + 26

c. Add

35

Therefore, the answer is 35.

Read the description of the equation carefully: the flower's height h is equal to 12 + 2.25w, where w is the number of weeks that pass.

If w = 0, this means no time has passed, and so h would be the flower's starting height:

12 + 2.25•0 = 12 + 0 = 12

After 1 week, w = 1, its height would be

12 + 2.25•1 = 12 + 2.25 = 14.25

After another week, w = 2, its height would be

12 + 2.25•2 = 12 + 4.5 = 16.5

and so on.

For every week that passes, the flower grows another 2.25 inches, which is exactly what the last option is saying.

Answer:

(3.1)(4.1)

Step-by-step explanation:

Answer: B) a + c = 10

8a + 5c = 59

Step-by-step explanation:

We know that 10 total people went, so the first equation has to be equal to 10. The total was $59, so the second equation should be set equal to $59. Now that the second equation is for cost, we must make it 8a + 5c to represent the cost of the adult and child tickets which are $8 and $5, respectively.

[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ second \ is \ correct .}}}[/tex]

Given that , a group of 10 people went to see a movie. The cost to go to the movie is $8 for an adult and $5 for a child. The total cost for thegroup was $59.

Let :-

[tex]\implies \bf No. \ of \ adult \ be \ denoted \ by \ a. \\\\\bf \implies No . \ of \ Children \ be \ denoted \ by \ c . [/tex]

Since the total number of people in group is 10 . Then ,

[tex]\implies \bf n_{adult} + n_{children} = 10 \\\\\bf\implies \boxed{\bf a + c = 10 }[/tex]

Now , the cost for an adult is $8 and for a child is $5. Hence ,

[tex]\bf\implies n_{adult}\times cost_{adult} + n_{child}\times cost_{child} = Total \ cost \\\\\bf \implies a \times \$ 8 + c \times \$ 5 = \$ 59 \\\\\bf\implies \boxed{\bf 8a + 5c =\$ 59 }[/tex]

Hence our overall answer matches with second option .That is ,

[tex]\red{\bf Option \ 2 } \begin{cases} \bf a + c = 10 \\\\\bf 8a + 5c = 59 \end{cases}[/tex]

Answer:

D

Step-by-step explanation:

It's not similar because when aligning the values they don't match. 3 × 5 = 15 so that bottom line matches but when you do the same thing to the other line: 5 × 3 does not equal 9. There is no similarity between the two triangles.
