90 = 2 x 3³ x 5
51 = 3 x 17
26 = 2 x13
GCF = 1 // There is no other common factor that is common for all the 3.

Answer: Greatest Common Factor is 1
-----------------------------------------------------------------------------------------
5x-2y = -10
Multiply by 6
= 30x -12y=-60
3x+6y = 66
Multiply by 2
= 6x+12y = 132
So
30x-12y=-60
6x+12y=132
Add those variables
36x= 72
X= 2
This would help
Answer:
6x
Discussion:
7x = 7 times x
x = 1 times x
So both terms are "like" terms in x:
7x - x = (7-1)x = 6x :D
If an item has been discounted 30%, then it is currently worth 70% of the original price. This tells us that $49 is 70% of the original price. Therefore, you need to divide $49 by 70% to get your answer (you have to work backwards; remember that you would have multiplied the original number by 0.7 to get 49):
49÷(70/100)= $70
Therefore, the price of the original product was $70
Time taken = depth / rate
Time taken = 312 / 114
Time taken = 2 14/19
