X is the Scale factor so 18/6=X
X=3
Another way to check. the work is 6 x 3 = 18
Hope this Helped. :)
The answer is C) 21, because 6/14 is simplified to 3/7. assuming it’s a pattern 3/7, 6/14, 12/21.
The answer is 3.06
0.34
x 9
_________
3.06 Just multiply 0.34*9=3.06 then count two places left to place the decimal point in the proper place
Answer:
x=14
Step-by-step explanation:
(x + a)/(ax) = b/x
a= 2
b = 5
(x + 2) /(2x) = 5/x
cross multiply
x * (x+2) = (2x)*5
x^2 + 2x = 10x
x^2 - 8x = 0
x ( x -8) = 0
We get two solutions
x = 0, 8
the solution 0 is extraneous
the solution 8 is valid.
