1 over 2 equals 2 over 4 equals 4 over 8.
Hope this helps! :)
First you want to find out how many marbles you start with so it'd be 8+7=15. You start with 15 marbles. If you randomly drew a blue marble, it'd be 8:15 and if you drew a yellow marble without replacing the blue one, it'd be 7:14 or 50-50 chance.
Answer:
2x² + 4x
Step-by-step explanation:
= (3 - 1)(x + 2)(x)
= (2)(x + 2)(x)
= (2x + 4)(x)
= 2x² +4x
Answer:
-71
Step-by-step explanation:
- 4 x (+1 --5) x (+1 - -5) /6 - (42 - -5)
1 - -5 = 6 and 42 - -5 = 47
-4 x 6 = -24
-24 x 6 = -144
-144 / 6 = -24
-24 - 47 = -71
