Answer:

Step-by-step explanation:

y - 9 = 1/5(x-2)

distribute the 1/5

y - 9 = 1/5x - 0.4

add 9 to both sides

y = 1/5x - 0.4 + 9

combine

y = 1/5x + 8.6

Answer:

A. ( 1 × 1 / 10 ) + ( 2 × 1 / 100 ) + ( 4 × 1 / 1000 )

Step-by-step explanation:

A number is written in expanded form if it shows the sum of the values of the individual digits that make up the number.

To write 0.124 in expanded form, follow these steps:

(i) Take the digits one after the other and multiply it by its value depending on its place.

Taking the first digit - 0

The value is 0 unit, where a unit is 1

Now multiply 0 by 1

=> 0 x 1

=> 0

Taking the second digit - 1

The value is 1 tenth, where a tenth is 1 / 10

Now multiply 1 by 1 / 10

=> 1 x 1 / 10

Taking the third digit - 2

The value is 2 hundredth, where a hundredth is 1 / 100

Now multiply 2 by 1 / 100

=> 2 x 1 / 100

Taking the fourth digit - 4

The value is 4 thousandth, where a thousandth is 1 / 1000

Now multiply 4 by 1 / 1000

=> 4 x 1 / 1000

(ii) Add the results obtained in (i) above

=> (0 x 1) + ( 1 x 1 / 10) + (2 x 1 / 100) + ( 4 x 1 / 1000)

=> ( 1 x 1 / 10) + (2 x 1 / 100) + ( 4 x 1 / 1000)

Therefore,

0.124 in expanded form is ( 1 × 1 / 10 ) + ( 2 × 1 / 100 ) + ( 4 × 1 / 1000 )

1. Jackie is saving money to buy a new cell phone. The cell phone costs $175, but she has

Serggg [28]

Answer:

32%

Step-by-step explanation:

<h3>Given that:</h3>

Jackie is saving money to buy a new cell phone.
The cell phone costs $175
she has already saved $56

The percent of the cost of the cell phone has Jackie saved

In order to find the percent of the cost of the cell phone has Jackie saved,

divide the cost of the cell phone by the amount of the money Jackie saved
Multiply the result (1) by 100

See below how it's done:

$\dfrac{56}{175} \times 100$

dividing yields:

$0.32 \times 100$

multiplying yields:

$32\%$

Alternative:

Instead of dividing,we can consider reducing the fraction and multiply that with 100 to get the answer.

$\dfrac{56}{175} \times 100 \\ \implies \frac{8}{25} \times 100 \\ \implies 8 \times 4 \\ \implies \boxed{32\%}$

In conclusion:

Jackie has saved 32% of the cost of the cell phone
