The graph shows the cost C in dollars of W pounds of blueberries a proportional relationship. select all the true statements
labwork [276]

Answer:

A, D

Step-by-step explanation:

Cost ($) = C

lbs (Blueberries) = W

One pound of blueberries costs $2.75 because to find how much 1 lb is you need to divide by 6.

6 is the number of pounds at that point in the graph, so you divide both the pounds and cost by 6 to find how much 1 lb is.

To find how much 5 lbs costs, multiply both the cost and number of pounds ($2.75 to 1 lb) by 5.

2.75 * 5 is 13.75 (This means C is wrong)

Do the same but with 12 for D

2.75 * 12 is 33, so D is correct

You could do the same method as above for E, but the easier way to do this is to see that the relationship of 3:9 is equal to a 1:3 ratio, which is the same as what the pounds to cost ratio is (which is 1:2.75)

Hope this helps! ^_^

Value of x is 3.2x-9.6=38.4?
Svetradugi [14.3K]

Answer:

The steps that can be done to both sides of the equation is: Add 9.6, then divide by 3.2

Step-by-step explanation:

Solve the equation:

3.2x - 9.6 = 38.4

-First you add both sides 9.6:

3.2x -9.6 +9.6 = 38.4 +9.6

3.2x = 48

-Then, you divide both sides by 3.2:

\frac{3.2x}{3.2} = \frac{48}{3.2}

x=15
