Answer:
(-3,5)
Step-by-step explanation:
6x+7y=17
-6x+5y=7
2y=10
y=5
6x+5(5)=7
6x+25=7
6x=7-25
6x=-18
x=-3
(is/of) = (Percent/100) then cross multiply to solve
(31,300/x) = (7.6/100)
3,130,000= 7.6x ; divide by 7.6
x = 411842.1
round to 411,842

Hope this helps! If I could have brainliest I'm trying to rank up.
Step-by-step explanation:
First find the probability of each color being drawn.
We need to find the total number of marbles first.
4 + 3 + 6 = 13
Everything will be over 13.
Probability of a white marble being drawn --> 4/13
Probability of a blue marble being drawn --> 3/13
Probability of a red marble being drawn --> 6/13
Now to find the probabilities of more than one being drawn, we can multiply.
Part A:
6/13*6/13=36/169
Part B:
3/13*3/13=9/169
Part C:
6/13*6/13=18/169
Part D:
7/13*7/13=49/169
