Soln:
Let mikhale's age be X
Gabrielle's age be 3X
Sum of their ages is 44
To find,
their ages.
X+3X=44
4X=44
X=44/4
X=11
mikhale's age= 11
Gabrielle's age = 3x11=33
Sum of their ages 44
Thus we have got their ages.Gabrielle's age is 33 and Mikhale's age is 11.

Answer:
Step-by-step explanation:
Given that the bag contains black and red marbles.
Number of black marbles in the bag = 2
Number of red marbles in the bag = 3
Total number of marbles in the bag = Number of black marbles + Number of red marbles = 2 + 3 = 5
Let us have a look at the formula for probability of an event E, which can be observed as:
Now, the marble chosen at first is replaced.
Therefore, the count remains the same.
Now, the <em>required probability</em> can be found as:
Answer: y = 12.50x + 45
Step-by-step explanation:
if x is the number of hours and you pay $12.50 per hour then we can come up the expression 12.50x
You will be charge $45 as an initial fee so it will be 12.50x + 45 and that has to equal the total cost which is y.
y = 12.50x + 45
Answer: 2
Step-by-step explanation: add 10 to both sides so -10+10=0 and -6+10=4
then you have 2x=4 simplify
