Kyra purchased a pack of 20 erasers. She kept 8 erasers and equally divided the rest among three friends. Which expression tells how many erasers each friend received?

Given:

Total number of erasers = 20

Kyra kept 8 erasers and equally divided the rest among three friends.

To find:

The expression that tells about the number of erasers each friend received.

Solution:

Total number of erasers = 20

Kyra kept 8 erasers.

Number of friends = 3

Let x be the number of eraser each friend received.

Number of eraser divided amount three friends = 3x

Now,

Erasers kept by Kyra + Erasers divided amount three friends = Total erasers

Divide both sides by 3.

It can be written as

Therefore, the required expression is and its value is 4.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
