Thats a proportion. i'll show you the formula that is easier to solve with that is more universal and you can try to see how it relates to that one seeing as this topic is VERY important.

You know that 20%=.2

Let x be the number

.2x=50

x=250

If you need more help still just tell me.

Jack and Jane are married and both work. However, due to their responsibilities at home, they have decided that they do not want

Sergeeva-Olga [200]

By setting up a system of equations we can easily solve this problem. Let's denote Jane's working hours with x and Jack's working hours with y. Since they don't want to work more than 65 hours, the first equation is x+y=65. The second equation is 14x+7y=770. By solving this system of equation $\left \{ {{x+y=65} \atop {14x+7y=770}} \right.$ , we find that y=20 hours, which is Jack's maximum working hours.

The prism has a volume up to 150.find the length of the prism

Varvara68 [4.7K]

Step-by-step explanation:

We have to know that in order to solve for the volume of a rectangular prism, we have to use this formula: l * w * h. This stands for length multiplied by width multiplied by height.

Let's look at the numbers we already have. The height of the prism is 4 feet and the width is 5 feet. When we multiply them together, we got 20 feet.

The volume of this prism adds up to 150 square feet. To find the length of this prism, we have to divide 150 by 20.

$150 / 20=7.5$

Our final answer: l = 7.5 feet

We can check our answer by multiplying all the numbers together.

4 * 5* 7.5 = 150

Answer:

M is 1.5

Step-by-step explanation:

Use M = 1/O

Replace 1 with a letter such as K

So you use M = K/O

Substitute values

0.5 = K/6

To get K times 0.5 by 6

You get 3

So K=3

Use the equation from the start to find M

M=3/2
