Answer:
c 35%
Step-by-step explanation:
2 green,5 yellow, 6 red,and 7 blue marbles
2+5+6+7 = 20 marbles
P(blue) = blue marbles / total marbles
= 7/20
= 35/100
=35%
The numbers are 3 and 7
Step-by-step explanation:
Let the first number be x and the second number be y
Then according to given statement
One number added to three times another number is 24
x+3y=24 Eqn 1
Five times the first number added to three times to other number is 36
5x+3y=36 Eqn 2
Subtracting Equation 1 from equation 2
Dividing both sides by 4
Putting x=3 in equation 1
Dividing both sides by 3
Hence,
The numbers are 3 and 7

Answer:
- x - 14
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
f(x) - g(x) = 4x - 8 - (5x + 6) = 4x - 8 - 5x - 6 ← collect like terms
(f - g)(x) = - x - 14
