Answer: D) 0.78
Step-by-step explanation:
Add all the given probabilities to find the answer:
45/100 + 18/100 + 15/100 = 78/100 = 78% or 0.78
3x+y=-5
12x+5y=27
Let y =-5-3x
Insert y into equ.2
12x+5(-5-3x)=27
12x-25-15x=27 den rearrange
-3x=2 den x =-2/3
Den put xinto equ 1
3(-2/3)+y=5
-2+y=5(collect like terms)
Y =7

Answer:
I think it is a bit not for shore
Answer:
4
Step-by-step explanation:
Rate of change = Slope (if Sidelength = x, and perimeter= y)
(1,4) and (2,8) are point (if it was a line)
Use the slope formula...
(8-4)/(2-1)=
4/1=
4
