Answer:
Mary- $18
Jane- $30
Step-by-step explanation:
Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.
x(3+5) = $48
3x + 5x = $48
8x = $48
8x/8 = $48/8
x = $6
3($6):5($6) = $18:$30
C=3 that’s the answer I think
Answer:

Answer:
a = 256; r = 
Step-by-step explanation:
The general form of the geometric sequence is:
a, ar, ar², ar³, . . .
where 'a' is the first term of the sequence;
'r' is the common difference.
Fourth term of the sequence = ar³ = 32
Sixth term of the sequence = ar⁵ = 8
Dividing both the equations, we get:

⇒ r² = 
⇒ r = 
Therefore, we get a = 32 X 8
a = 256
The first term of the sequence is 256 and the common difference is
.
Hence, the answer.
