Answer:
14x+ 61
Step-by-step explanation:
5+ (14x+56)
14x+ 56+5
14x+61
Answer:
Step-by-step explanation:
Let the number of the problems the team could solve before is x.
<u>Then we have:</u>
- x + 40% = 42
- 1.4x = 42
- x = 42/1.4
- x = 30
They were able to solve 30 problems before the new mathletes joined
Hey there! I'm happy to help!
We have 24 total beads, and we have 6 red ones. This gives us a probability of 6/24, which simplifies to 1/4. However, we do this twice with replacement (we put the bead back, so the probability stays the same), so we multiply that probability twice to find the probability of it happening twice.
1/4×1/4=1/16
Therefore, the probability that both beads are red is 1/16.
Have a wonderful day! :D
Independent. The second event is not affected by the first event. Such as, if you pick up a card without replacement.
The answers: 3•sqrt34 and 12
Depending on the theorem of Pythagoras
Answer N1: sqrt(9^2 + 15^2)
Answer N2: sqrt(15^2 - 9^2)
