Answer:

14

Step-by-step explanation:

How many 1/2s are in 7? Then, write a multiplication equation and a division equation that answer the question.

Let the number of 1/2s = x

Hence:

Division Equation =

7 ÷ 1/2

Multiplication Equation =

= 7 × 2/1

= 14

There are 14 1/2s in 7

Solve the following system: Y = x -2 2x + y = 5

Veronika [31]

Answer:

x = 7/3

y = 1/3

Step-by-step explanation:

y = x - 2.... (1)

2x + y = 5.... (2)

Rearranging equation (2), we have

y = -2x +5 .... (3)

Let's multiply equation (1) by 2 so that we can easily simplify by substitution.

Therefore, it becomes 2y = 2x - 4 ... (4)

We add equation (3) and (4)

3y = 1

y= 1/3

Now, substitute (y= 1/3) in equation 1

It becomes:

1/3 = x - 2

x = 1/3 + 2

Simplifying with a LCM of 3

x = (1 plus 6, all over 3)

= 1+6/ 3

= 7/3

satela [25.4K]

Given :-

A dealer sold a photocopy machine at Rs 4200 with 13% VAT to a retailer.
The retailer added transportation cost of Rs 250 , profit Rs 300 and local tax Rs 150 and sold to consumer .
Customer has to pay 13% VAT .

To Find :-

Amount to be paid by the customer .

Solution :-

Here , according to the question ,

$\sf\dashrightarrow Cost\ of \ machine \ = \ Rs 4200$

$\sf\dashrightarrow VAT = 13\%$

Therefore cost after adding VAT ,

$\sf\dashrightarrow Cost = Cost_{initial}+13\% of Cost_{initial}\\$

$\sf\dashrightarrow Cost = Rs4200 + Rs 4200 \times \dfrac{13}{100}\\$

$\sf\dashrightarrow Cost = Rs4200 + Rs546\\$

$\sf\dashrightarrow \bf{ Cost = Rs 4746}$

Again the values added by the retailer before selling to customer ,

Transport = Rs 250
Profit = Rs 300
Tax = Rs 150

Therefore total cost after adding these ,

$\sf\dashrightarrow Cost = Rs( 4746+ 250+ 300 + 150 )\\$

$\sf\dashrightarrow\bf { Cost = Rs 5446}$

Again Selling price after addition of 13% VAT ,

$\sf\dashrightarrow SP = Rs 5446 + 13\% \ of \ Rs 5446\\$

$\sf\dashrightarrow SP = Rs 5446 + \dfrac{13}{100}\times 5446 \\$

$\sf\dashrightarrow SP = Rs (5446 + 707.98) = Rs ( 5446 + 708)\\$

$\sf\dashrightarrow \underline{\underline{\bf SP_{to\ the \ customer} = Rs 6154}}$

Hence the amount to be paid by the customer is Rs 6154 .

Patty made a banner that has an area of 112 square inches. The length and width of the banner are whole numbers. The length is 7

il63 [147K]

Answer:

The width of the banner is 4 inch and the length of the banner is 28 inch

Step-by-step explanation:

Given

Length is seven times its width

Let the width be "X", then length would be 7X

The banner is of rectangular shape.

Its area is 112 square inches

$X* 7X = 112\\7X^2 = 112\\X^2 = 16\\X = 4$

Hence, the width of the banner is 4 inch and the length of the banner is 4*7 i.2 28 inch
