I think the answer is D) 8 over 32 multiplied by 7 over 31
Hopefully that helped! :)
Answer:
x=54
Step-by-step explanation:
2x + 2 = 3x - 52
subtract 2x from both sides, now u have:
2 = x - 52
add 52 from both sides, now u have
54 = x
2x + 3x = 100
5x=100
x=100/5
x= 20
Therefore, 2x=2×20=40
3x=3×20=60

Answer: 1:50
The scale factor is 5/250 = 1/50
Answer:
P(yellow or red) =8/15
Step-by-step explanation:
There are 15 marbles, 3 green, 4 blue, and 5 red marbles.
3+4+5 = 12
That means there are 15-12 = 3 3 yellow marbles.
3 green,
4 blue
5 red
3 yellow
To find the probability of yellow or red, we add the number of yellow and red marbles together over the total number of marbles
P(yellow or red) = (yellow +red)/ total
= (3+5)/ 15
=8/15
