Hi again!

5c + 2(10-c)

Use the distributive property 

=5c+(2)(10)+(2)(-c)

=5c + 20 -2c 

= 3c + 20


--------------------------

(x+8)-(x-8)

x + 8 -  x + 8 

= 16 


Best of luck!

The following graph shows the cost c, in dollars, of p pounds of strawberries at a local grocery store.
lorasvet [3.4K]

Answer:

A. The ordered pair (5, 3.5) represents 5 lbs. of strawberries cost $3.50.

B. The cost per pound of strawberries is shown at (1, 0.7).

C. The relationship shown in the graph is a direct variation because as the pounds of strawberries increase, the cost also increases.

Explanation:

A. The coordinate is in (x,y). The x-axis represents the pound of strawberries and the y-axis represents the cost of the strawberries.

B. The cost for one pound of strawberries can be calculated to find the exact value of y (cost) when x is 1. The graph shows 5 lbs. of strawberries cost $3.50 so divide $3.50 by 5 lbs. to find the cost per pound of strawberries. 3.5 ÷ 5 = 0.7. On the graph, the cost for one pound of strawberries is at (1, 0.7)

C. A direct variation in a graph is shown when both x and y increase or decrease together. In this case, as the pounds of strawberries increase, the cost of the strawberries also increases.

Chris cut a rope into two pieces. One piece was 11.36 meters long and the other piece was 13.46 meters long. About how long was
rosijanka [135]
If you would like to know about how long was the rope before Chris cut it and you would like to round each length to the nearest tenth to estimate the total length of the original piece of rope, you can calculate this using the following steps:

11.36 meters = 11.4 meters
13.46 meters = 13.5 meters

11.4 + 13.5 = 24.9 meters

Result: The rope was 24.9 meters long (before Chris cut it) - rounded to the nearest tenth.

How do you sole this question kelpie sold cameras on her web site. She bought the cameras for $65 each included a 60% markup to
postnew [5]
So 65 dollars was what she paid
each camera INCLUDED a 60% mark UP so
she sold each at a 60% markup

65 dollars=100% of origonal camers
she sold them for 100+60=160% of origonal price
65 dollars=100%
percent means parts out of 100 so
160%=160/100=1.6

find 160% of 65
'of' means multiply so
1.6 times 65=104

she sold each camera at $104
