Answer C
This is because the order can be switched but the answer will not change
(X (Fiona) + Y (Gary))/20 (10 days for each of them so it’s 20)
(x+y)/6
Your answer would be x=3. You would start by combining like terms such as 5x and -7x and getting -2x. Then you would move the +5 to the other side by subtracting it from both sides. You would get -6=-2x. After that you would divide -2 on both sides and since they are both negatives, it would be a positive 3.
P(2, 5) * 3.5 = P' (7, 17.5)
Q(2, 1) * 3.5 = Q' (7, 3.5)
9/10 + 7/100
find the common denominator for 9/10 which is 100
multiply by 10 for 9/10
(9)(10)=90
(10)(10)=100
90/100+7/100
Answer:
97/100
