First you can add 50 dollars to 450 dollars which is 500 then divide that 500 by 2 and that is 250

Answer:

$450+$50= X

X=$500

Step-by-step explanation:

The sale price is $450.00, so you take that amount and $50.00 which the amount he paid less and add them both. We do this because we want to see the original price of the computer. If it mentioned the original price already and the amount $50.00 and asked the sail price instead, we would have to subtract to get the answer.

Here we have to add.

450+50=500

(add the dollar sign)

$450+$50=X

X=$500

a rectangular fish tank 60 centimeters by 15 centimeters by 34 centimeters is 1/3 full of water. find the volume of water needed
son4ous [18]

Answer:

20,400\ cm^{3}

Step-by-step explanation:

step 1

Find the volume of the tank

V=(60)(15)(34)=30,600\ cm^{3}

step 2

we know that

If the tank is 1/3 full of water

then

the volume of water required to completely fill the tank is equal to 2/3 of the tank capacity

so

(2/3)30,600=20,400\ cm^{3}

Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. He has a 10% alcohol solution and a 15% alcohol solut
Inessa05 [86]

The equation is 0.1x + 0.15(50-x)=1.20(50)

Step-by-step explanation:

Here you need 50ml of 12% alcohol solution.

You have 10% and 15% alcohol solutions.

Take volume of 10% alcohol solution to be x ml

Take volume of 15% alcohol solution to be y ml

Form equations;

x+y=50 ml--------------------------equation 1

0.1x +0.15 y= 12% of 50

0.1x+0.15y=6-----------------------equation 2

Now you have simultaneous equations, use a graph tool to solve for values of x and y as attached.

or use the mixture equation the get value of x

0.1x + 0.15(50-x)=1.20(50)

The values of x and y are ;

(x,y) (30,20) which means;

y is 20 ml of 15% alcohol

x is 30 ml of 10% alcohol
