Thank you, you’ll motivate me to work out :)
Answer:
-1
Step-by-step explanation:
1/3 - 2/5 = x/15
Make denominators equal.
5/15 - 6/15 = x/15
Cancel the denominators.
5 - 6 = x
-1 = x
I beleive the system of equations would be:
a+b=4000
0.1a+0.04b=352
I cant say for sure because the question did not list the cost of a and b together but rather the number of both items together
1. Well I know that if you add anything with 10 you could do a magic trick.
10+6 just take the zero out and then you get 16
