The problem is false because 6 multiplied by 6 is 36 so it would be false
A*5+b*2=145
a +b =50 | * -2
5a +2b=145
-2a -2b = -100
----------------------
5a-2a = 145-100
3a= 45
a=45:3
a=15 questions are worth 5 p
b=50-15=35 questions worth 2 p
Can be 40/100 but when you simplify it will give you 4/10 give me thanks if it helps!!! I hope it did;))))
