Answer: The answer is (B) 2x + 3(3x – 5) = 51
.
Step-by-step explanation: We are given three options and we are to select which choice shows the result of substituting 3x – 5 into the second equation for y.
So, y = 3x - 5.
Since the standard form of a linear equation i two variables is ax + by = c, so the second equation as given in the options must be of the form 2x + 3y = 51.
If we substitute y = 3x - 5, then this equation becomes
2x + 3(3x - 5) = 51.
Thus, (B) 2x + 3(3x – 5) = 51 is the correct option.
Answer:
A)
- National brand cornflakes is 0.174 = .17/oz
- Store label cornflakes is 0.514 = .15/oz
B) The larger box is cheaper per ounce.
C) 2.09 – .30 = 1.79 for 12 ounces. So than $1.79/12= .15/oz.
They would both be the same so there would be no better deal.
