Step-by-step explanation:
Well, Let's find out!
Gloria says,
2(3x+6)-9x=3*4
By using distributive law
6x+12-9x=12
12-3x=12
-3x=12-12
-3x=0
x=0/-3
So she is not correct
The first statement means:
b=i+12,
The third statement means:
b-3=4(i-3),
b-3=4i-12
b=4i-9
Using the value for b from the first statement in the third statement gives you:
i+12=4i-9
-3i=-21
i=7: and since b=i+12
b=19
So Ben is 19 and Ishaan is 7.
Answer: 3
Step-by-step explanation:
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
Therefore, 10m = 30
m = 30/10
m = 3
Mark has 3 marbles
