This is a linear equation
y=mx+b
y=50x+400 (when x equals the number of hours played)

1000=50x+400
*first, isolate the variable (x)
-50x=-1000+400
*divide by -50 to get x by itself
x=20+8

The volume of a cuboid is 176cm
IRISSAK [1]

Answer:

.08cm or 0.08cm

Step-by-step explanation:

First of all, we can see that 20mm is in millimeters, not centimeters.

If we convert the ones in centimeters to millimeters, it will result in decimals, which I want to avoid, but you could also do it that way.

There are 10 mm in 1 cm, so I multiply all of the values in cm by 10.

So now, we have that the volume is 1760mm, the length is 110mm, and the width is 20mm.

The formula for the volume of a cuboid is: w*l*h = volume

We have the width, length, and volume, so let's plug it in.

20*110*h=1760

To solve for h:

1. Multiply 20 and 100

2200*h=1760

2. Divide both sides by 2200

h = 1760/2200

3. Divide right side

h = 0.8

Keep in mind that this is in millimeters. In centimeters, it would be .08

What is the positive solution of x2 – 36 = 5x?
Wewaii [24]

Answer:

Required positive solution of the given quadratic equation is 9.

Step-by-step explanation:

Given Equation,

x² - 36 = 5x

We need to find positive solution of the given equation.

We solve the given quadratic equation using middle term split method.

x² - 36 = 5x

x² - 5x - 36 = 0

x² - 9x + 4x - 36 = 0

x( x - 9 ) + 4( x - 9 ) = 0

( x - 9 )( x + 4 ) = 0

x - 9 = 0 and x + 4 = 0

x = 9 and x = -4

Therefore, Required positive solution of the given quadratic equation is 9.
