Answer:
m=2
Step-by-step explanation:
42=8m+13m
or,42=21m
or,42/21=m
or,m=2
This is the required answer for m.
To check,
42=8×2+13×2
42=16+26
42=42
Correct
Step-by-step explanation:
= 5 • ( 4• x )

Step-by-step explanation:
It would be the very top of the division problem, so for example, if we take. a look at the lower image below, we see that the number 6 is the number that would be the (first) number that would be the quotient.
Answer:
Very top, (e.g)<em> "the number 6"</em>
Answer:
Step-by-step explanation:
n and d are the number of nickels and dimes, respectively.
"there are 20 coins"
n+d = 20
d = 20-n
"total value is $1.40"
0.05n + 0.10d = 1.40
0.05n + 0.10(20-n) = 1.40
-0.05n + 2 = 1.40
0.05n = 0.6
n = 12
d = 20-m = 8
