Dime value: $0.10
Nickel value: $0.05
For this word problem, you are asked to create an algebraic expression (an equation) for the unknown variables.
Now, we know that a dime is worth $0.10 or 10 cents and a nickel is worth $0.05 or 5 cents. So, all you would have to do is create an equation that takes those values into account.
5n + 10d
Your algebraic expression would be B. 5n + 10d
I hope this helps!
Answer:D
Step-by-step explanation:
Answer: 79 degrees
Step-by-step explanation:
4x+1 + 3x+4 = 180
7x + 5 = 180
7x = 175
x = 175:7 = 25
m8 = 3x + 4 = 3*25 + 4 = 79
