Answer:
1/12
Step-by-step explanation:
You are just dividing 1/3 by 1/4 to get 1/12.
They are congruent to each other. Any two polygons with the scale factor of 1 will be congruent.
500,000 *(1 + x) = 600,000
we're going to solve for x
first divide both sides by 500,000
1 + x = 1.2
subtract 1 from both sides
x = 0.2
turn that into a percent by multiplying it by 100
0.2*100 = 20%
the magazine sales increased by 20%
Solve for x by simplifying both sides of the inequality, then isolating the variable
x > 9 or x < 5
Hope this helps lad! :)
