Answer:
Y+9>= -1
Step-by-step explanation:
The sum of a number y and 9 means that we wanna add Y and 9, but since y is a variable and 9 is just a number, we can't add them.
Now we have Y+9
Now, we plug in our inequality sign which is at least.
at least is >=
Now we have Y+9>=
And all you have to do is place the negative one after the inequality sign, and you get Y+9>= -1
Hope this helps! :)
You need the greatest common factor of the two numbers. In this case, 20 is a factor of 100, meaning that Angie can make 20 groups, each with 5 cookies and 1 brownie.
Answer:
15pi/60 = pi/4 hopefully this helps :)
Step-by-step explanation:
Angle in radians = arc / radius
15pi/60 = pi/4
Answer:
See below
Step-by-step explanation:
1: (b+1)*(3b)*(b-5)
(3b^2+3b)(b-5)
3b^3-15b^2+3b^2-10b
3b^3-12b^2-10b
2: πr^ 2(h/3)
π(n-2)^2(12n/3)
π(n-2)(n-2)(12n/3)
π(n^2-2n-2n+4)(12n/3)
π(n^2-4n+4)(12n/3)
π(n^2-4n+4)(4n)
π(4n^3-16n^2+16n)
<em>(I'm not 100% sure with this one)</em>
3: (lwh)/3
((k-2)(2k+3)(3k))/3
((2k^2-4k+3k-6)(3k))/3
(6k^3-12k^2+9k^2-18k)/3
(6k^3-3k^2-18k)/3
2k^3-k^2-6k
