Answer:
Hi:) Do you have a specific question on something or just some tips for those desired good grades?
Step-by-step explanation:
Answer:
If p - q = 10, then p = 10 + q. Replace the other p with this:
q(2(10 + q) - 10) = 3600
q(20 + 2q - 10) = 3600
q(10 + 2q) = 360
Answer: Distributive property of the multiplication.
Step-by-step explanation:
You did not post Gretchen's expression, but i gues that it is 3*(x + y)
I guess that it is the distributive property of the multiplication.
For 3 numbers, A, B and C, we have that:
A*(B + C) = A*B + A*C
here we have:
3*x + 3*y
We can do the inverse process to the distributive property, and get:
3*x + 3*y = 3*(x + y)
which i guess is Gretchen's expression.
Answer:
<h2>x = 70°</h2><h2>y = 55°</h2><h2>z = 55°</h2>
Step-by-step explanation:
Look at the picture.
We know: the sum of the angles measure in the triangle is 180°. Therefore we have the equation:
Solve it:
Angle α and β = x are the supplementary angles. Supplementary angles add up to 180°. Therefore:
i think it would be " a population of birds increasing in numbers and then remaining constant over time"
