Answer:
Apples = 24
Pears = 40
Step-by-step explanation:
Let u be the unit of fruit in the basket,
number of apples: ![3u +7](https://tex.z-dn.net/?f=3u%20%2B7)
number of pears: ![5u -9](https://tex.z-dn.net/?f=5u%20-9)
now to find u, we equate the two equations.
![3u+7=5u-9](https://tex.z-dn.net/?f=3u%2B7%3D5u-9)
Now simplify.
![5u-3u=7+9](https://tex.z-dn.net/?f=5u-3u%3D7%2B9)
![2u=16](https://tex.z-dn.net/?f=2u%3D16)
![u=8](https://tex.z-dn.net/?f=u%3D8)
Now we can find the original number of apples and pears by substituting u.
so original number of apples = ![3u = 3(8) = 24](https://tex.z-dn.net/?f=3u%20%3D%203%288%29%20%3D%2024)
and original number of pears = ![5u = 5(8) = 40](https://tex.z-dn.net/?f=5u%20%3D%205%288%29%20%3D%2040)
Answer:
The value of the x-coordinate is -3.5.
Step-by-step explanation:
To determine the x-coordinate you have to look at how far the point is on the x-axis which is the sideways line of the graph.
Point W is between -3 and -4 on the x-axis which would make the x-coordinate -3.5.
Hope this helps!
Answer:
$1.75
Step-by-step explanation:
The selling for each candy bar may be determined by a set of linear equations. This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations.
It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation
.
Let the cost of a snack bag be s and that of a candy bar be c, then if on Wednesday the students or 23 snack bags and 36 candy bars that raised $114.75 on Thursday the seventh so 37 snack bags and 36 candy bars that raised $146.25
23s + 36c = 114.75
37s + 36c = 146.25
14s = 31.5
s = $2.25
23(2.25) + 36c = 114.75
36c = 114.75 - 51.75
36c = 63
c = 63/36
= $1.75
