The product of a number and 4 increased by 8 -36
Julli [10]
4x + 8 - 36 first subtract 36 from 8 to get the simplified equation 4x + (-28), or 4x - 28. As you cannot combine these terms, this is as far as you can go. Hope this helps! :)

What is the speed of a snake that moves 20 m in 5 seconds ?
pogonyaev

The speed of the snake is 8.95 miles per hour.

Step-by-step explanation:

Step 1:

The snake travels at a speed of 20 meters in 5 seconds.

We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.

The distance covered in 1 second = \frac{20}{5} =4.

So the snake is moving at a distance of 4 meters per second.

Step 2:

To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.

So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.

4 meters per second = 2.23694(4) = 8.94776 miles per hour.

Rounding this off, we get the speed of the snake as 8.95 miles per hour.

joja [24]
Let b=the number of boxes, c=cost of the pens
The expression that represents the total cost of the pens if a box costs 4 dollars and then she gets a 1 dollar discount for every additional box is c(b)=3b+1. We got this from the original equation c(b)=4+(4-1)(b-1). Simplify this and you will get c(b)=3b+1.

Which expression completes the statement to form a true equation? 2 + 4² = ???
Anastaziya [24]

Answer:

3^2 +9

Step-by-step explanation:

Since 2+4^2 is 16+2 which is 18, you need to find the expression equivalent to 18. 25 doesn't work so eliminate that right away. 9^2=81 so that isn't right either. 2^3+9=17 so that is incorrect. Lastly, 3^2+9=18 so that is the correct answer.
