2.4 +2/5 = 2.8
2.8 / 1/5= 70 / 5 = 14 / 1
Answer:
The answer to your question is below
Step-by-step explanation:
-4x² + 9y² + 32x + 36y - 64 = 0
-4x² + 32x + 9y² + 36y = 64
-4(x² + 8x ) + 9(y² + 4x ) = 64 Factor coefficients
-4(x² + 8x + 4²) + 9(y² + 4x + 2²) = 64 - 64 + 36 Complete trinomials
-4(x + 4)² + 9(y + 2)² = 36 Factor trinomials
Divide by 36
Simplify
Let
c = cereal
m = mixed nuts
c = 3m
c + m = 6
3m + m = 6
4m = 6
m = 6/4
m = 3/2 or 1 &1/2 cup
then c = 3m
c = 3(3/2)
c = 9/2 or 4 &1/2 cup
Variable is the answer because it needs to be solved and doesnt mean anything
A because there are 26 red cards(half of the deck) and then there is only one of each of the other cards making the probability ratio 28/52. If you simplify it can be turned into 7/13
