Answer:
3 weeks
Step-by-step explanation:
Set the number of weeks when they are equal as x.
We can then write these equations.
25x + 52 = 37x + 16
Subtract 25x from both sides.
52 = 12x + 16
Subtract 16 from both sides.
36 = 12x
Divide both sides by 12
x = 3
The answer is 3 weeks.
area of a circle is PI x r^2
2 = d/2 = 5.4/2 = 2.7 cm
using 3.14 for PI
3.14 x 2.7^2 = 22.89 square inches
360 degree in a circle, shaded area is 180 degree, which is 50%
so 22.89 x .5 = 11.45 cm^2
x = -2
x = -8
please follow me
x ^ 2 = 144
x = 12, x = -12
Check:
12 * 12 = 144
-12 * -12 = 144
