kilograms of yellow potatoes bought is 8330 kg
<em><u>Solution:</u></em>
Given that James buys 245 kilograms of red potatoes
He buys yellow potatoes that weigh 34 as much as the red potatoes
To find: kilograms of yellow potatoes bought by James
Let "y" be the kilograms of yellow potatoes bought
Let "r" be the kilograms of red potatoes bought
kilograms of red potatoes bought = 245 kilograms
r = 245 kilograms
From given information,
Yellow potatoes weigh 34 as much as the red potatoes
here "as much as" means product or multiplication
Kilograms of yellow potatoes bought = 34 x kilograms of red potatoes bought

Thus kilograms of yellow potatoes bought is 8330 kg
The answer cannot be expressed in mixed number since whole numbers has no fractional part
The answer you are looking for is Y = 2/3X - 5.
To find this, you must fill in the equation Y = MX + B, where Y = -1, M = 2/3, and X = 6. Filling in for those variables, you should get -1 = 2/3(6) + B. Now, you solve for B. Multiply 6 and 2/3 together, by putting 6 over 1 and multiplying straight across. 6 times 2 is 12 and 1 times 3 equals. This will give you 12/3, which simplified, is 4. Then, subtract 4 from both sides to get B = -5. Finally, fill in Y = MX + B, but this time only fill in M (2/3) and B (-5). This making Y = 2/3X - 5 the answer. Here's a graph to show this is the correct answer.
I hope this helps!
