Answer:

Suppose there is an advertisement in news paper that you can buy 3.5 kgs of coffee in $24.5. So find the cost of 1 kg coffee.

Step-by-step explanation:

Consider the provided information.

We need to find examples of decimals in a newspaper or magazine write a real world problem in where you have to divide decimals.

Suppose there is an advertisement in news paper that you can buy 3.5 kgs of coffee in $24.5. So find the cost of 1 kg coffee.

To find this simply divide the decimals as shown:

$\frac{24.5}{3.5} =7$

Hence, the cost of 1 kg coffee is $7.

Consider the following case:

Suppose a student earns $113.75 for painting and he works 13 hours, find his hourly rate.

In the above problem, to find the hourly rate, we need to divide the decimal 113.75 by 13.

The answer is:

$\frac{113.75}{13}=8.75$

Dylan has a bank that sorts coins as they are dropped into it. A panel on the front displays the total number of coins inside as

vesna_86 [32]

Answer:

1). System of equations- D + Q = 90 and D + 2.5Q = 175.50

2). There are 33 dimes and 57 quarters in the bank.

Step-by-step explanation:

Dylan has a bank that sorts coins as they are dropped in it.

A panel shows the total number of coins inside as well as the total value of these coins.

Let the number of dimes in the bank = D

and the number of quarters in the bank = Q

If the panel shows total number of coins = 90

Then the equation will be

D + Q = 90 -------(1)

And the panel displays the amount of the coins = $17.55

Then equation will be

0.10D + 0.25Q = 17.55 [1 Dime = $0.10 and 1 quarter = $0.25]

D + 2.5Q = 175.50 ------------(2)

Now we subtract equation (1) form equation (2)

D + 2.5Q - (D + Q) = 175.50 - 90

D + 2.5Q - D - Q = 85.5

1.5Q = 85.5

Q = $\frac{85.5}{1.5}$

= 57

By putting Q = 57 in the equation (1)

D + 57 = 90

D = 90 - 57 = 33

Therefore, there are 33 dimes and 57 quarters in the bank.

The new car you bought this year cost $42500. The value of the car

Valentin [98]

Answer:

10% multiplied by 6 = 60%

60% of 42500 is 25500

42500-25500= 17000

i multiplied 10% by 6 because 2027 is 6 years away and i subtracted 42500 by 25500 because it says it "decreased"

Use the graph to write an equation that represents the relationship between X and Y.

Yuki888 [10]

Answer:

The equation is $y=x-3$

Step-by-step explanation:

Observing the graph

Let

$A(3,0), B(15,12)$

step 1

Find the slope m

$m=(12-0)/(15-3)=12/12=1$

step 2

Find the equation of the line into point slope form

$y-y1=m(x-x1)$

with the point $A(3,0)$ and the slope $m=1$

substitute

$y-0=(1)(x-3)$

$y=x-3$
