Answer:
I'd say $18
Step-by-step explanation:
I cant really tell, but your best guess is $18
Need a picture! Then I will be happy to help :
Let James be x years old
Joe = 10 + x
After 8 years
18 + x = 3(x)
18 + x = 3x
18 = 2x
x = 9
Joe is 19
James is 9
To do this problem, we need one more piece of information. He need to know the percent of the quarters that are from New York.
If you had that number, just multiply it by 300.
For example, if 10% of the coins were from New York, just multiply by 0.1.
0.1 x 300 = 30
This is fairly simple
Plug in the numerical values given for each variable.
5(-2) -3(2) -(-3)
-10 -6 + 3 (negative x negative = positive)
-16 + 3
-13 is the final answer
