(A) For x representing the cost of one of Tanya's items, her total purchase cost 5x. The cost of one of Tony's items is then (x-1.75) and the total of Tony's purchase is 6(x-1.75). The problem statement tells us these are equal values. Your equation is ...
... 5x = 6(x -1.75)
(B) Subtract 5x, simplify and add the opposite of the constant.
... 5x -5x = 6x -6·1.75 -5x
... 0 = x -10.50
... 10.50 = x
(C) 5x = 5·10.50 = 52.50
... 6(x -1.75) = 6·8.75 = 52.50 . . . . . the two purchases are the same value
(D) The individual cost of Tanya's iterms was $10.50. The individual cost of Tony's items was $8.75.
O wpuld say that d is correct
Answer:
c. 5 - 17
Step-by-step explanation:
a. -15 - 3 = -18
b. -3 - (-9) = 6
c. 5 - 17 = -12
d. -6 - (-6) = 0
Solution:
Given:
To determine if an ordered pair is a solution, we substitute the x and y-values into the inequality and check if it is true.
Thus,
Therefore, the correct answers are selected as shown below;
