Answer:

x = 3y

x + y = 24

The number of social media advertisement purchased is 18

And, the number of newspaper advertisements purchased is 6

Step-by-step explanation:

Let us assume the number of social media advertisement purchased be x

And, the number of newspaper advertisements purchased be y

As three social media advertisements for every one newspaper advertisement is purchased

So,

y = x ÷ 3

x = 3y

And it is ended by total of 24 advertisement

That means

x + y = 24 ............(1)

Now put the value of x in equation 1

3y + y = 24

4y = 24

y = 24 ÷ 4

= 6

x = 3y

= 6 × 3

= 18

Now  The equations are

x = 3y

x + y = 24

Step-by-step explanation: To divide mixed numbers, first rewrite the mixed numbers as improper fractions.

So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.

Remember that dividing by a fractions means the same thing

as multiplying by the reciprocal of that fraction.

In other words, 3/5 ÷ 5/2 can be rewritten as 3/5 · 2/5.

Finally, multiplying across the numerators and the

denominators, we have 6/25.

The result of the division of 3/5 divided by 2 1/2 is: 6/25.

Here, we have,

given that,

3/5 divided by 2 1/2

To divide mixed numbers, first rewrite the mixed numbers as improper fractions.

So here, 3/5 is already a fraction and 2 and 1/2 can be written as 5/2.

Remember that dividing by a fractions means the same thing

Answer:

the last one because when using the distributive property,  you get

4x + 12 - 2x - 10

Answer:

4x + 12 + 2x + 10

Step-by-step explanation:

4( x + 3 ) -2( -x -5 )

1. Multiply 4 and x = 4x

2. Multiply 4 and 3 = 12

3. Multiply -2 and -x = 2x

(turns positive as there are 2 negative signs)

4. Multiply -2 and -5 = 10

(turns positive as there are 2 negative signs)

Answer:

Option 4

Step-by-step explanation:

Finding Area

The area of the semicircle is

[tex](\pi/2)(4^2) \approx (3.14/2)(16)=25.12[/tex]

The area of the trapezoid is

[tex]\frac{1}{2}(8+20)(8)=112[/tex]

Adding these, we get the area to be about 137.12 square inches.

Finding Perimeter

The arc length of the semicircle is

[tex]\pi(4) \approx 3.14(4)=12.56[/tex]

The sum of the lengths of the outer sides of the trapezoid is

[tex]10+10+20=40[/tex]

Adding these, we get the area to be about 52.56 inches.

Answer:

Total Amount Paid by Piper = $84.87

Option C is correct.

Step-by-step explanation:

Total boxes of cookies = 3

Cost of 1 box of cookie = $24.95

Delivery charges paid = $12.99

We need to find total amount Piper paid.

First we will find cost of 3 boxes of cookies:

Cost of 1 box of cookie = $24.95

Cost of 3 box of cookie = $24.95 x 3

                                        = $74.85

Now, add cost of 3 boxes of cookies with delivery charges paid to get total amount paid.

Total Amount Paid = Cost of 3 box of cookie + Delivery charges paid

                               = 74.85 + 12.99

                               = 87.84

So, Total Amount Paid by Piper = $84.87

Option C is correct.

Answer: D

Step-by-step explanation:

Answer:

2,315 coffee beans.

Step-by-step explanation:

1 tub = 1,000

1 large bag= 100

1 small bag = 10

Raoul has:

- 2 tubs

- 3 large bags

- 1 small bag

- 5 beans on the counter

2 x 1,000 = 2,000

3 x 100 = 300

10 + 5 = 15

then, add all of the (bold) numbers together.

2,000 + 300= 2,300

2,300 + 15 = 2,315

Raoul has 2,315 beans altogether.

Step-by-step explanation:

The onlt one that makes sense

Justin will have enough money to buy the item. The amount Justin will pay is $25.92.

A sales tax is the amount of tax that is charged on the sales of goods and services. Tax is the compulsory sum levied by the government or an agent of the government on goods and services. Taxes increase the price of an item.

Percentage is the fraction of an amount expressed as a number out of hundred. The sign used to represent percentages is %.

Amount Justin would pay for the item = (1 + tax) x initial cost of the item

(1 + 0,08) x $24

= 1.08 x 24 = $25.92

$25.92 is less than the amount Justin has for the gift. This means that Justin has enough money to buy the gift.

Approximation to the nearest tenth means to find the tense place . e.g.

25632 - in this case the '32'

then you round it upwards or downwards according to rule that if digit at once place is

from 0 - 4 you round downwards,

from 5 - 9 you round upwards for example

25632 goes to 25630

248 goes to 250

Therefore approximate to nearest tenth means to make the number a nearest multiple of 10 with respect to the rule that if digit at once place is

from 0 - 4 you round downwards,

from 5 - 9 you round upwards

Look at the next place value to the right to round a number to the nearest tenth (the hundredths). Remove all the digits to the right if it's 4 or less. If it's 5 or higher, add 1 to the digit in the tenths place before removing all the digits to the right.

Jane:

Cost of 3 postcards= $1.05

Cost of 1 post card = 1.05 ÷ 3

                              = $ 0.35

Rosi:

Cost of 5 postcards= $1.75

Cost of 1 post card = 1.75 ÷ 5

                              = $ 0.35

Tanya:

Cost of 8 postcards= $2.80

Cost of 1 post card = 2.80 ÷ 8

                              = $ 0.35

As unit rate is same, Cost and number of postcards are in proportion.

Cost of cards = 0.35 * number of cards

y = 0.35*x

y = 0.35x
