The ratio of circumference of circle to its diameyer is the number π ,a mathematical constant, commonly approximated as 3.14159 :)
Answer:
.8
Step-by-step explanation:
5 red marbles, 2 Green marbles and 3 black marbles = 10 marbles
P (red or black) = number of red or black/ total
= (5+3)/10
=8/10
decimal form = .8
Answer:
first number=15 second number=6
Step-by-step explanation:
lets take the first and second numbers as "a" and "b"
a-b=9
a+2b=27 (solve these equations simultaneously)
eliminating a
-3b= -18
b= 6
then substitute in the first equation
a-6=9
a=9+6
a=15
I really hope you know how to solve equations simultaneously
hope this helped
I’m not sure whether there is a typo in the function but I might have the answer.
If f(x) = 5(x+1)+3 = -12 then you can solve for x.
5(x+1)+3 = -12
5x + 5 + 3 = -12 << expand the brackets
5x + 5 = - 15 << minus 3
x + 1 = -3 << divide everything by 5
x = -4 << minus 1
I don’t know if this helps x Sorry
