Answer:
(q + 4) + (d - 3) + n
Step-by-step explanation:
You have to add all of them.
You have to add q, d, and n.
so q + d + n
and then you add four more q's so
(q + 4) + d + n
and then you lost 3 dimes so
(q + 4) + (d - 3) + n
and nothing happened to n so that is the answer.

Answer:
a = -10
Step-by-step explanation:
-0.4a + 3 = 7
subtract 3 from each side
-0.4a + 3-3 = 7-3
-.4a = 4
Divide each side by -.4
-.4a/ -.4 = 4/-.4
a = - 10
A number line can be used to find the difference because you can count from 28 to 34 and the number you get will be your answer.
