X=-3x+20
Add 3x to both sides to move the -3x over
4x=20
Then do 20 divided by 4
X=5
Answer:
I believe it would be the 3rd answer.
Step-by-step explanation:
That answer is the only one where not only do one of the systems have that point but they both do. That is where they intercept. Plus when you fit in the x and y points in the equations they match up. Hope that helps!
3 dozen= 36, you need 720.
720/36= 20.
This means you'll need to scale up the recipe to a factor of 20. In other words, you'll need to multiple the amount of each ingredient required by 20 in order to have enough cookies for 360 people to each have two.
Answer:
5
Step-by-step explanation:
Let a = number of pieces of chocolate bought by Amin.
Let b = number of pieces of chocolate bought by Bob.
b = 2a
(a - 3)(b - 3) = 14
ab - 3a - 3b + 9 = 14
a(2a) - 3a - 3(2a) = 5
2a^2 - 3a - 6a = 5
2a^2 - 9a - 5 = 0
(2a + 1)(a - 5) = 0
2a + 1 = 0 or a - 5 = 0
a = -1/2 or a = 5
Amin cannot have bought -1/2 pieces of chocolate, so we discard the soluion a = -1/2.
a = 5
Answer: 5
I think the answer is 8x8 please dont judge me if it is wrong.
