Since 3 squared is 9 and 4 squared is 16, the square root of 13 will fall somewhere between 3 and 4
well, we know the "sum" of both angles is 90°, notice the rectangle in the corner, so we can say that the angles are simply complementary angles, thus
Let x be the month on which the fee for two plans are equal.
Therefore,
150 + 10x = 50 + 30x
10x - 30x = 50 - 150
-20x = -100
x = 5
Cumulative cost = 150 + 10(5)
= 150 + 50
= 200
Hence, Karan will pay a cumulative cost of $200 dollars with either plan to go to the gym for 5 months.
I don’t know how to show how I got it but the answer is X=12.
Answer:
yes
they are equivalent because lets say the X = 3 then you would have to answer
3 + 3 + 1 + 3 + 2 + 3 + 1 + 3
and that would = 19
and then on the other equation
5 x 3 + 4 = 19
So the both equal the same.
