Answer:
To solve, use a simple one-step equation
Known: Number of coins; Number of Nickles.
Unknown: Number of Dimes.
a) To find the number of Dimes
b) Use x (or virtually any letter) to represent the unknown number of dimes
c) 9+x=13
d) Subtract 9 from both sides to cancel out the 9 and isolate the variable on one side. x=4
e) 9+4=13, so yes, the answer is correct
Answer:
4.5
Step-by-step explanation:
13.5 - 9 = 4.5
18 - 13.5 = 4.5
22.5 - 18 = 4.5
Answer:
162
Step-by-step explanation:
24 x 3 = 72
5 x 18 = 90
90 + 72 = 162
I believe that f(x) = 3(x-1). From the distance between the f(x) values you can infer that the factor in front of x must be 3. Then for x=0 the value is -3. So f(x) = 3x - 3 or 3(x-1).
