From the question, we are informed that Johnny has 30 marbles while Mark has m marbles.
Since Johnny has 10 times as many marbles as Mark, it means that Johnny has: = 10 × m = 10m

m = 30/10
m = 3
Mark has 3 marbles
Answer:
C. 9p + 1
Step-by-step explanation:
2(4p - 3) + (p + 7)
Step 1: Distribute 2 in the first term to both terms in the parenthesis. You can drop the parenthesis on the second term (p + 7)...
2(4p) + 2(-3) + p + 7
Now multiply
8p - 6 + p + 7
Now simplify by combining like terms
8p + p -6 + 7
9p + 1 (8p + p = 9p, -6 + 7 = 1)
