Answer:
A. 3.85
Step-by-step explanation:
- If 11 oranges cost $2.35, we could calculate the cost of each of these oranges, simply dividing the total cost ($2.35) between the amount of oranges bougth (11). This will give us the cost of a single orange, that is, the unitary cost=
. - Then, if we want to know the cost of 18 oranges, we just have to multiply the cost of a single orange (0.21) by 18: 0.21x18 = 2.85
The number of doughnuts in bags is 4 times the number of bags of doughnuts. So the number in B bags of doughnuts will be
... 4B
The number of doughnuts in cartons is 10 times the number of cartons of doughnuts, so the number in C cartons will be
... 10C
The total number of doughnuts (T) is the sum of those in bags and those in cartons:
... T = 4B +10C
Is it necessary
Can I get it cheaper elsewhere
Will it last a while
These are just 3 I came up with. I do not know if they are what your teacher would have put.
Hi there!

For a system to have infinite solutions, the lines have to be the same. We can begin by rearranging the given equation into the format y = mx + b:
2y - 4x = 6
Move x to the opposite side:
2y = 4x + 6
Divide all terms by 2:
y = 2x + 6
The answer choice that matches this is the first one.
