Answer: The copy machine makes 171 copies in 4 minutes and 45 seconds.
Step-by-step explanation:
Let's dissect the question. The copy machine makes 36 copies per minute.
36 per min.
To see how many copies it makes in 4 minutes and 45 seconds, we multiply 36 * 4.75. 45 seconds is 3/4ths of a minute, or 0.75 of a minute.
It makes 171 copies in 4 minutes and 45 seconds.
Answer:
Part A: 12 + X
Part B: 25 + 2
Step-by-step explanation:
First thing you need to know is the
difference between an expression and an
equation. An expression does not have an
equal sign, while an equation does.
To write an expression for Part A, first write
the 12 (the amount he got on Saturday).
Then, we need to write the addition sign (to
find the total amount Bill earned). We don't
know how much Bill earned on Sunday, so
use any variable (I used x). Because we're
writing an expression, do not write an
equal sign.
To write an expression for Part B, first write
the amount of dogs his friend Steve walked
using a variable because we don't know
that number (I used the variable s). Then,
since Bill walked 2 more than twice as
many dogs Steve walked, write the s
multiplied by the 2 or just 2s. Now add the
addition sign (to find the total amount Bill
walked). Add a 2 because Bill walked 2
more dogs than twice as many Steves walked.
Hope it helps!
