Answer:169 pounds

Step-by-step explanation: to find how many pounds one candy would cost, divide the 130 pounds by the initial 10 sweets, you should get 1 sweet equals 13 pounds, so if 1 sweet cost 13 pounds, than multiply the cost of 1 sweet by 13 to get 169 pounds for 13 sweets

Answer:169 pounds

Step-by-step explanation:

if 10 sweets=130

then 1 sweet = 130/10 which is 13

so 1 sweet = 13 pounds

13 sweet = 13 sweet multiplied by 13 pounds=169 pounds

so 13 sweet is 169 pounds

3. Consider the linear equation 2y - 3x = 5.

nignag [31]

Answer:

Step-by-step explanation:

2y - 3x = 5

2(-2) - 3x = 5

-4 - 3x = 5

-3x = 9

x = -3

(-3,-2) is another solution

(-1,1)

2y - 3x = 5

2(1) - 3(-1) = 5

2 + 3 = 5

5 = 5

true, the point is a solution to the equation because the equation is true after substituting x and y with the point (-1,1)

(4,1)

2y - 3x = 5

2(1) - 3(4) = 5

2 - 12 = 5

-10 = 5

not true, the point is not a solution to the equation because the equation is not true after substituting x and y with the point (4,1)

c. You can use the points from the given (-1,1) and (-3,-2) to form a line. You then shade whichever half solves the solution using points on the graph.
