-8.8
Step-by-step explanation:
We begin by simplifying the parenthesis through multiplication. Parenthesis is a structure which signals multiplication happening.
We now begin combining like terms across the equal sign by performing the inverse or doing the opposite. Move first the 8.11 by subtracting it from both sides.
Now, move 4.3v across by subtracting it from both sides.
Finally, we divide both sides by the coefficient of v.
Answer:
The equation which gives the total cost y of x pounds of dried cherries is
Step-by-step explanation:
Given:
Cost of 3 pounds of dried cherries = $15.90
Cost of 5 pounds of dried cherries = $26.50
Cost of 9 pounds of dried cherries = $47.70
Let Number of of pounds of dried cherries be 'x'
Let Total Cost be denoted by 'y'
We need to find the equation for total cost y for x pounds of dried cherries.
First we will find the cost of each pound of dried cherries.
Now we know that;
3 pounds of dried cherries = $15.90
1 pound of dried cherries = Cost of 1 pounds of dried cherries
Hence By using Unitary method we get;
Cost of 1 pounds of dried cherries =
Total Cost of dried cherries is equal to Number of of pounds of dried cherries multiplied by Cost of 1 pounds of dried cherries.
framing in equation form we get;
Hence The equation which gives the total cost y of x pounds of dried cherries is
