<span>Twice the sum of a number and 3 = 2(n + 3)
</span><span>three times the difference of the number and 3 = 3(n - 3)
so
</span><span>Twice the sum of a number and 3 is equal to three times the difference of the number and 3:
</span>2(n + 3) = 3(n - 3)
2n + 6 = 3n - 9
n = 15
answer
2(n + 3) = 3(n - 3)
n = 15
um is the end a 3 and 2 or 32 or 3*2?
Answer:
Step-by-step explanation:
We have given that melissa used 4 cups of sugar to bake 54 cookies.
That means 1 cup of sugar will be used to bake by unitary method
We have to find the ratio of cups to the cookies
We are using 1 cup of sugar
And cookies will be
The way to get the equation for the radius (r) is to get r by itself. So divide each side by 4pi
500/4pi=r^2
Now take the square root of each side to get the equation of r.
sqrt(500/4pi)=r
