How do i add 6.75 & 3.75?

Stella [2.4K]

Answer:

It's like adding whole numbers, but with a dot. add 75+75=150

Because 150 is more than 100, you add the 1 to the whole numbers, the 6 and the 3. Add 3+6+1=10

So your answer is 10.5

3. There are about 1.61 kilometers in 1 miles. Let x represent a distance measured in kilometers and y represent the same distan

WINSTONCH [101]

We have been given that there are about 1.61 kilometers in 1 miles.

Let x represent a distance measured in kilometers and y represent the same distance measured in miles.

We can set two equations from the given information as:

$x=\frac{1}{1.16}*y$ (Number of kilometers in terms of number of miles)

$y=1.61*x$ (Number of miles in terms of number of kilometers)

Therefore, $x=\frac{1}{1.16} y$ and $y=1.61*x$ will be our equations.

If a1=10 and an+1=-5an-1 then find the value of a4<br><br>Please explain!

Umnica [9.8K]

Answer:

$a_4=-1271$

Step-by-step explanation:

We are given that:

$a_1=10$

And:

$a_{n+1}=-5a_n-1$

And we want to find:

$a_4$

This is a recursive formula. So we can simply substitute in each value. For instance, a₂ will be:

$a_2=a_{(1)+1}=-5a_{1}-1=-5(10)-1=-51$

Thus, a₃ will be:

$a_3=a_{(2)+1}=-5a_2-1=-5(-51)-1=254$

Finally, a₄ will be:

$a_4=a_{(3)+1}=-5a_3-1=-5(254)-1=-1271$
