To add 1/10 and 8/100, they must have the same denominator.

To do this, multiply 1/10 by 10/10 (which equals one, so it doesn't change the value of the fraction).

Now you have 10/100 and 8/100. To add them, simply add the numerators and keep the denominators the same.

This results in 18/100, which can be simplified to 9/50.

You make 1/10 and 8/100 have the same denominator. So that would be 10/100+8/100=18/100 which simplifies to 9/50!

The sum of 5 consecutive integers is 100. What is the first number in this sequence?

So we can call first number "n"

Then all five integers would be n, n+1, n+2, n+3, n+4

So sum of them would be 5n + 10 = 100

Now you can solve for n:

5n + 10 = 100

5n = 90

n = 18

Verify: 18 + 19 + 20 + 21 + 22 = 100. All good.

So answer is 18

Answer:

Step-by-step explanation:

We are given that x and y are functions of time t such that x and y is a constant. So, we can write the following equation:

$x(t)+y(t)=k,\text{ where $k$ is some constant}$

The rate of change of x and the rate of change of y with respect to time t is simply dx/dt and dy/dt, respectively. So, we will differentiate both sides with respect to t:

$\displaystyle \frac{d}{dt}\Big[x(t)+y(t)\Big]=\frac{d}{dt}[k]$
