Answer:

x = 8

Step-by-step explanation:

29=7x + 5 -4x

add like terms: 29 = 3x +5

get your x variable on one side

24 = 3x

divide by 3

x = 8

check!

29 = 7(8) + 5 -4(8)

29 = 56 + 5 -32

29 = 51 - 32

29 = 29

Hey! :)

Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.4 : 5 ( = 9 too little )8 : 10 ( = 18 just right)12 : 15 ( = 27 too much)So per necklace, 8 yellow beads and 10 blue beads would be needed.

Hope this helps! :)

kiruha [24]

The discount amount would be $1470.00

the new cost of the car would be $19530.00

For given question,

A car dealer gave a 7% discount to the first 50 people through the door.

the car you are interested in cost $21,000.00

We need to find the discount amount and the new price of the car.

A car dealer gave a 7% discount.

this means, to find the discount amount, we need to find the 7 percent of $21,000.00

⇒ discount amount = 7 percent of $21,000.00

⇒ discount amount = (7 / 100) × 21,000.00

⇒ discount amount = $1470.00

So, the new price of the car would be,

the new price of the car = original price - discount amount

⇒ the new price of the car = $21,000.00 - $1470.00

⇒ the new price of the car = $19530.00

Therefore, the discount amount would be $1470.00

the new cost of the car would be $19530.00
