Answer:
Choice B
Step-by-step explanation:
Divide both of the choices by the price and ounces. You will find that the unit rate of choice B is lower.
Work
3.49/25=0.14
4.79/45=0.106
Therefore choice B has the lowest unit rate and that is the answer!
Answer:
(0, 7) is an ordered pair solution to 3x + y = 7
Step-by-step explanation:
Given the equation 3x + y = 7, find a solution (ordered pair).
There are an infinite number of possible solutions. Let's focus on just one:
Let x = 0. Then y = 7, and (0, 7) is an ordered pair solution to 3x + y = 7
<span>10x + 7y = 49
</span><span>10y – x = 70 so x = 10y - 70
substitute </span>x = 10y - 70 into 10x + 7y = 49
10x + 7y = 49
10(10y - 70) + 7y = 49
100y - 700 + 7y = 49
107y = 749
y = 7
x = 10y - 70 = 10(7) - 70 = 0
answer
(0, 7)
