Step-by-step explanation:

4x = 20

x = 20/4 = 5

x/2 = 8

x = 8 x 2 = 16

x + 8 = 3x

8 = 3x - x

8 = 2x

8/2 = x

4 = x

x = x + 5/2

2x = 5/2

x = 5/2 x 2

x = 5

Answer:

x+8=3x

Step-by-step explanation:

4x=20

4x/4=20/4

x=5

The solution to the first equation is x=5.

x/2=8

2(x/2)=2(8)

x=16

The solution to the second equation is x=16.

x+8=3x

x+8-x=3x-x

8=2x

8/2=2x/2

x=4

The solution to the third equation is x=4.

x=x+5/2

x-x=x+5/2-x

-x=5/2

x=-5/2

The solution to the fourth equation is x=-5/2.

The equation x+8=3x has the solution to x=4.

docker41 [41]

Answer:

The number of car washed per club is:

The art club = 533 cars

The music club = 633 cars

The drama club = 414 cars

Step-by-step explanation:

The art club, music club, and drama club at Glendale High School raised money last summer by washing cars.•

For the art club

The art club raised about $3,200 and charged $6 per car.•

$6 = 1 car

$3200 = x

6x = 3200

x = 3200/6

x = 533.33333333 cars

Approximately = 533 cars

The music club earned approximately $3,800, charging $8 for each car

$8 = 1 car

$3800 = x

8x = 3800

x = 3800/8

x = 633.33333333 cars

Approximately = 633 cars

The drama club took in nearly $2,900, at a cost per car of $7.

$7= 1 car

$2900 = x

7x = 2900

x = 2900/7

x = 414.28571429 cars

Approximately = 414 cars

The number of car washed per club is:

The art club = 533 cars

The music club = 633 cars

The drama club = 414 cars

Rebecca has a credit line of $6,500. She had a previous balance of $398.64 and made a payment of $250. The total of her purchase
valentina_108 [34]

Answer:

$5093.37

Step-by-step explanation:

To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.

Previous balance = $398.64

Purchases = $1,257.99

Payment = $250

Credit Line = $6,500

Now first we add together her purchases and previous balance.

398.64 + 1,257.99

This will give us:

$1,656.63 Total deductions.

Now we subtract that to her credit line.

$6500.00 - $1656.63

$4843.37

Now we take her payment and add it to her credit line.

$4843.37 + $250

$5093.37

So Rebecca's available credit is $5093.37.
