Answer:
We can’t solve for x and y
Step-by-step explanation:
2(4x-1) + 3(3-2x)=0
distribute
8x-2+9-6x=0
add like terms
2x+7=0
subtract 7 from both sides
2x= -7
divide both sides by 2
x=-7/2
Answer:
2/35
Step-by-step explanation:
Assuming that this is without replacement,
The total amount of marbles is 2+9+3+7, or 21.
9 are yellow, 3 are white. this makes 12.
The probability of selecting a white or yellow marble is 12/21.
Now without replacement (comment if it is with replacement.), there are 20 marbles left, and 2 are Cordovan. This means there is a 2/20 chance then of picking a Cordovan marble.
After multiplying the fractions we get
(12/21) * (2/20) = 2/35.
There is a 2/35 chance of selecting a yellow or white, then a cordovan marble.
Answer:D
Step-by-step explanation:
Answer:
= 17 v^2 + 7v + 11
Step-by-step explanation:
Given that:
= (8v^2+6v+5)+(9v^2+v+6)
by removing brackets
= 8v^2 + 6v + 5 + 9v^2 + v + 6
Addin like terms:
= (8v^2 + 9v^2) + (6v + v)+ (5 + 6)
= 17 v^2 + 7v + 11
