Answer:
12 problems
Step-by-step explanation:
All problems were of equal value
Let x be the number of problems in the test
We apply a rule of three
x ------------------------------- 100%
(x-10) --------------------------- 17%
(x-10)*100%/(x) = 17%
(x-10)/(x) = 0.17
(x-10) = 0.17*x
0.83*x = 10
x = 12.05
x = 12 problems
x-y+16
add the like terms, 6 and 10 which is 16. since the variables are not like terms, thats your final answer. hope it helped :)
