Answer:
10/40 or a 1 in 4 chance he will grab a red marble
Step-by-step explanation:
You add up all of the marbles;
10+15+15
40
Now you take the number of red marbles are divide it by 40;
10/40
That is your answer.
Subtracting a negative number is the same as adding a positive number
assume your number is n
n - (-10) = 6
n + 10 = 6
subtract 10 from both sides
11 - (-5) = 16. Hope that helped!
Hello :
<span>6x=-32-10y ...(1)
11x=8-10y ....(2)
by (1) : x = -32/6 -(10/6)y .....(*)
x = -16/3-(5/3)y
subst in (2) : 11(</span>-16/3-(5/3)y)-10y .......calculate y....then x by : (*)
