Answer:
5x + y = 9
3x + 2y = 4
-10x - 2y = -18
3x + 2y = 4
-7x = -14
x = 2
5(2) + y = 9
10 + y = 9
y = -1
(2, -1)
the answer is c

2.19 • 10^8. You first make a number in between 1-10, so it would be 2.19, then you count how many 0s there are behind your numbers and how many numbers are behind the decimal point, so that would be 6 0s and 2 numbers behind decimal point so then you get 10^8.
Answer:
Step-by-step explanation:
Let us assume that the total cost of the grapes = x $.
Given that it costs 1.55 $ for one pound. We are asked to determine how much it would cost for 3.5 pounds.
note that for one pound you pay 1.55 so how much should you pay for 3.5 pounds? Clearly, the cost increases with the increase in weight of the item.
