(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.
160/4 = 40 mph so that would be the answer simply divide
Ummm this has to be in your textbook
Answer:
4x⁶(1+2x²)²
Step-by-step explanation:
Factor out the common term 2x³
Use Multiplication Distributive Property: (xy)^a=x^a y^a
Simplify 2² to 4
The use the power rule and you get 4x⁶(1+2x²)²
