Would it be 10-2?=8 quotient means divide
-4y+5x=8
3y-3x=-3 --> divide by (3) y-x=-1
then multiply by (4) 4y-4x=-4
-4y+5x=8
4y-4x=-4
---------------
x=4
then plug x=4 in
4y-4x=-4
4y-4(4)=-4
4y-16=-4
4y=12
y=3
solution: (4;3)
Answer:
12x10x5+11x11=721
Step-by-step explanation:
A=1
B= -1
C= 1/4
B^2-4ac
(-1)^2 -4(1)(1/4)

0 = 1 solution
Answer:
9/64
Step-by-step explanation:
The probability that the marble on the first draw is blue is 3/8.
The probability that the marble on the second draw is blue is also 3/8.
So the probability that both are blue is:
3/8 × 3/8 = 9/64 ≈ 14%
