Answer:

8 feet

Step-by-step explanation:

Given that 96 sq. feet of tile is bought to retile the bathroom.

It means area of bathroom is 93/2 x^2 = 96\\=> 3 x^2 = 96*2=192\\=>  x^2 = 192/3 = 64\\=>\sqrt{x^2}  = \sqrt{64} \\=> x = 86 sq. feet

Width of bathroom be x

Given that the length of the bathroom is  one and a half times the width

Length of bathroom in term sod width = 1 1/2* x = 3/2 x

we know area of rectangle is given by length * width

therefore area of bathroom =( x* 3/2 x) = 3/2 x^2

Also area of  bathroom is 86 sq. feet, therefore

3/2 x^2 = 96\\=> 3 x^2 = 96*2=192\\=>  x^2 = 192/3 = 64\\=>\sqrt{x^2}  = \sqrt{64} \\=> x = 8

Thus, width of bathroom is 8 feet.

At a movie theater, the price of 2 adult tickets and 4 child tickets is $48. The price of 5 adult tickets and 2 child tickets is
Setler [38]

Answer:

adult=10

Child=7

One adult and one child=10+7=17

Step-by-step explanation:

Let a be the price of an adult ticket

c = price of the child ticket

2a+4c = 48

5a+2c = 64

Multiply the second equation by -2 and add to the first equation

2a+4c = 48

-10a-4c = -128

---------------------

-8a +0c = -80

Divide by -8

-8a/-8 = -80/-8

a = 10

Now find c

2a+4c=48

2(10)+4c=48

20+4c=48

4c=48-20

4c=28

4c/4=28/4

c=7

SOS! Can some please help me!
Wewaii [24]

Answer:

8.9

Step-by-step explanation:

1. DE:BC=AD:AB

2. AD=AB+BD, but according to the conditions AB=5, then

AD=5+BD.

3. after the substitution DE=16; BC=9; AB=5 and AD=5+BD into the formula:

16:9=(5+BD):5;

\frac{16}{9} =\frac{BD+5}{5};

BD=80/9 - 5≈3.9.

4. if AD=AB+BD, then AD=5+3,9=8,9

Wally chin, the owner of an exxon mobil station, bought a used ford pickup truck, paying $1,900 as a down payment. He still owes
My name is Ann [436]

Down payment of the ford pickup truck = $1,900.

It is said that down payment amount $1,900 owes 75% of the selling price.

Therefore, 100-75 = 25% is the downpayment of total Selling price.

Let is assume selling price is $x.

According to problem,

25% of the selling price equals down payment amount $1,900.

Let us convert above statement into an equation.

25% of x is 1,900.

That is 25% x = 1,900.

25% could be written as 25/100 or 0.25.

So, the above equation would become

0.25x = 1,900.

Dividing both sides by 0.25, we get

0.75x/0.25 = 1,900/0.25

x=7600

So, the selling price would be $7600.
