(4x - y)/(2y + x) when x = 3 and y = 3 is
(4(3) - 3)/(2(3) + 3) = (12 - 3)/(6 + 3) = 9/9 = 1
Answer: $6.20
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
We have to first find how much of the whole cake (1) that they all ate.
Boris eats 1/5 of the cake.
Maziy eats 1/5 of the cake.
Sanjay and Silas eat 1/5 of the cake.
Jack also has 1/5 of the cake.
The total fraction of cake eaten was:
1/5 + 1/5 + 1/5 + 1/5 = 4/5
Therefore,the fraction of the cake left is:
1 - 4/5 = 1/5
Yes, there is cake left.
Answer:
A.
Step-by-step explanation:
Since y=2, we can place 2 where y is, giving us the equation:
x+2=13
(And as a bonus, to solve this subtract 2 from each side, making x=11. If you were to graph the answer, you would have the point (11,2))
