Sofia can type the work in 10 hours. Nova can do it in 15 hours. They work together for 4 hours, then Sofia and Nova finish the

AlladinOne [14]

Answer:

2 days.

Step-by-step explanation:

Let, Sofia can type the x amount of work in 10 hours.

So, in one hour Sofia can type $\frac{x}{10}$ amount of work.

Again, Nova can type x amount of work in 15 hours.

So, in one hour Nova can type $\frac{x}{15}$ amount of work.

Hence, if they work together, they can type $\frac{x}{10} + \frac{x}{15} = \frac{6x + 4x}{60} = \frac{10x}{60} = \frac{x}{6}$ amount of work in one hour.

Therefore, working together they can type the x amount of work in $\frac{x}{\frac{x}{6} } = 6$ days.

So, they have to work for (6 - 4) = 2 days more to finish the work. (Answer)

If 4/5 – 3/10 = x + 11/2, find the value of<br>X.

ehidna [41]

Answer:

x = 85/60 or 17/12

Step-by-step explanation:

4/5 - 3/10 = x + 11/12

=> 8/10 - 3/10 = x + 11/12

=> 5/10 = x - 11/12

=> x - 11/12 = 5/10

=> x = 5/10 + 11/12

=> x = 5 * 6 / 10 * 6 + 11 * 5 / 12 * 5

=> x = 30 / 60 + 55/60

=> x= 85/60

Can I get help please?

Answer:

x = 1/4, y = 1/2

Step-by-step explanation:

First we can solve for y in each equation.

3x - 1/4 = y

y = 1/2(x) + 3/8

This means 3x - 1/4 = 1/2(x) + 3/8.

Simplifying, we get 5/2(x) = 5/8. This means x = 1/4. Now, we plug in x = 1/4 into the first equation to get

3(1/4) - 1/4 = y

3/4 - 1/4 = y

y = 2/4 = 1/2
