Sum of all natural numbers from100to300 which are divisible by 4and 5 is​
My name is Ann [436]

If x is a number that is both divisible by 4 and 5, then

\begin{cases}x\equiv0\pmod4\\x\equiv0\pmod5\end{cases}

4 and 5 are coprime, so we can use the Chinese remainder theorem to solve this system and find that x=20n is a solution to the system, where n is any integer. Simply put, any multiple of 20 fits the bill.

Now, there are 11 numbers between 100 and 300 that are divisible by 20 (100, 120, 140, and so on). We have 20n=100 when n=5, so the sum we want to compute is

\displaystyle\sum_{n=5}^{15}20n=\boxed{2200}

Evaluate please<br> 2x+(−6)∙(y+1) for x=−1.5 and y=−3
Andreyy89
First, you plug your given values in. Since x is 1.5, it will be multiples by 2x to get 3.2. Since y is -3, it will be added to 1 to get -2. Finally, the two are multiplied together to get -6.4 if I am correct.

Three times the difference of eight and twice a number is five times the number
Sophie [7]

Answer:

3*( 8-2n)=5n

The number is 24/11

Step-by-step explanation:

three times

3*

the difference of eight and twice a number

3*( 8-2n)

is five times the number

3*( 8-2n)=5n

To solve

Distribute

3*8 -3*2n = 5n

24 -6n = 5n

Add 6n to each side

24 - 6n +6n = 5n +6n

24 = 11n

Divide each side by 11

24/11 = 11n/11

24/11 =n

The number is 24/11
