Answer:
Probability of rolling a 2 and flipping a head will be
Step-by-step explanation:
If we roll one die then probability to get any one side is 
Therefore, probability to get 2 by rolling the die will be P(A) = 
Now we flip a coin then getting head or tale probability is 
Or probability to get head by flipping the coin P(B) = 
Probability of happening both the events (rolling a 2 and flipping a head) will be denoted by
P(A∩B) = P(A)×P(B)
= 
= 
Therefore, probability of rolling a 2 and flipping a head will be

Answer:
She will have 142 watermelons
Step-by-step explanation:
First let's put our ratio
10 : 71
Since our lemons are now 20 instead of 10 we will divide 20 by 10 to see how many time we multiplied it by.

which equals 2
To find our water melon we will multiply it by 2

which equals 142
She will have 142 watermelons
3y + 5x = -15
3y = -5x - 15 (Subtract 5x from both sides)
y = -5/3x - 5 (Divide everything by 3)
