Answer:
Part A: y=5x
Part B: B and D
Step-by-step explanation:
The ratio of the number of cases to the total cost is 1:5. So, an equation that can be modeled by this situation in slope-intercept form is y=5x.
The unit rate actually does equal the constant of proportionality, so this is not true.
The unit rate of the number of cases per dollar is 1/5, so this is true.
No, the graph starts on the origin, so this isn’t true.
Points (0,0) and (1,5) are on the graph, so this is true.
25 cases will not cost $120, they will cost $125.
X+4+2x-10=2x+1
3x-6=2x+1
X-6=1
X=7
Answer:
v=-3
Step-by-step explanation:
-1=1/3v
-1*3=v
-3=v
Answer:
I say A
Step-by-step explanation:
because it is the highest point.
Tayna bought 3 items that all share the same price.
So, we will call this 3x. Where x = a price.
Then Tony bought 4 items that each cost the same amount, but each was $2.25 less than the items that Tanya bought. So, we will call this 4(x - 2.55).
We put parentheses around the x and 2.55 because x = the price and Tony's items all are $2.55 less than Tanya's.
Now lets put the equation together and solve this.
3x = 4(x - 2.55)
It has an equal sign because both paid the same amount of money.
Let's do the distributive law of property with the 4.
3x = 4x - 10.2
-x = -10.2
Transpose the 4x.
Because both are negative, it's actually positive.
x = 10.2
Now let's substitute the x in the equation to see if it fits!
3(10.2) = 4(10.2 - 2.55)
After doing the work it comes out as 36=36.
But now back to the original question. What is the individual price for each person?
We know that Tayna's price for each item is $10.2. But what about Tony's?
Well in the question it said it's $2.55 less than Tayna's items.
$10.2 - $2.55 = $7.65
So, each of Tony's items is $7.65.
