6k-5
Step-by-step explanation:
8k-(5+2k) write the equation out
8k-5-2k distribute the (-) to everything inside the parenthesis
6k-5 combine like terms

Answer:
7:9
Step-by-step explanation:
Number of red balls = 10
Number of green balls = 6
Number of orange balls = 15
Number of blue balls = 14
Total numbers of balls = 45
Probability (odds against the red ball) = P( not red)
P(not red) = P(green) + P (orange) + P (blue)------------------------- (1)
P (green) = 6/45
P ( orange) =15/45
P (blue) = 14/45
Substituting in (1)
P(not red) = 6/45 + 15/45+14/45
= 35/45
= 7/9

Answer:
75/19 <-- exact form 3.94736842... <---decimal form 3 18/19 <--- mixed number form explanation: I used a site to solve it so i don't get it wrong, I am not entirely sure this is right either but I think so
Answer:
(-2,-10)
Step-by-step explanation:
So if y=5x and if y=9x+8 then those should be able to equal each other (substitution):
5x=9x+8
Subtract 5x from both sides:
0=4x+8
Subtract 8 from both sides:
-8=4x
Divide both sides by 4:
x=-2
If x=-2, then we can just plug it back into the first equation:
y=5(-2)
Simplify:
y=-10
