Divide by a whole number to get 40 which is 5 and then keep left over 3/8 to get mixed number of 5 3/8
Answer: exponential decay
Step-by-step explanation:
The best way for him to check his answer would be to simply plug in the value found for x into the equation.
4(2) - 6 = 2
8 - 6 = 2
2 = 2
Answer:
r=4
Step-by-step explanation:
Area of a circle is
A = pi* r^2
We know the area and 3.14 = pi
50.24 = 3.14 * r^2
Divide each side by 3.14
50.24/3.14 =3.14 /3.14 *r^2
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
You add 2x and 7x to get 9x
so the answer is 9x+5y
