NEED RN, WORTH 20! <br> What is the value of x?

max2010maxim [7]

Answer:

$x = 5.625$

Step-by-step explanation:

<u>Step 1: Make an expression</u>

<u /> $\frac{3}{4} = \frac{x}{7.5}$

<u>Step 2: Cross Multiply</u>

<u /> $\frac{3}{4} = \frac{x}{7.5}$

$4 * x = 7.5 * 3$

$4x = 22.5$

<u>Step 3: Divide both sides by 4</u>

<u /> $4x / 4 = 22.5 / 4$

$x = 5.625$

Answer: $x = 5.625$

What percent is the change in the price if the price was $100 and now it is $1250?

Vsevolod [243]

Answer:

1150%

Step-by-step explanation:

The percentage change is ...

percentage change = (amount of change)/(original amount) × 100%

= ((new amount) - (original amount))/(original amount) × 100%

= ($1250 -$100)/$100 × 100%

= 1150/100 × 100%

= 1150%

sasho [114]

Answer:

Answer:

Step-by-step explanation:

Let x represent the cost of one package of tulip bulbs.

Let y represent the cost of one bag of daffodil bulbs.

Ava bought 6 packages of tulip bulbs and 12 bags of daffodil bulbs for a total of $198. This means that

6x + 12y = 198- - - - - - - - - - - - -1

Grace spent $254 buying 14 packages of tulip bulbs and 12 bags of daffodil bulbs. This means that

14x + 12y = 254- - - - - - - - - - - - 2

Subtracting equation 2 from equation 1, it becomes

- 8x = - 56

x = - 56/-8

x = 7

Substituting x = 7 into equation 1, it becomes

6 × 7 + 12y = 198

42 + 12y = 198

12y = 198 - 42

12y = 156

y = 156/12

y = 13
