Answer:
exponential function
Step-by-step explanation:
geometric sequence
An = A1 * r^(n-1)
common ratio is 2
A1 = 1st term

There are 10 digits possible for each of the 4 places .
So the number of digits possible is 10^4 = 10,000
Answer:
it would be x=17 1/2
Step-by-step explanation:
i am going to go a little more into detail.
you would first have to divide each side to isolate the variable
x=5/2/7
simplifying steps:
you would have to change the 5 into 5/1
5/1÷2/7
now you have to keep the first number, change the sign, and then flip the last number, AKA KCF
5/1*7/2
35/2
and you can simplify this into a mixed number
17 1/2
hope this helps! have a nice day :)
Answer:
W = 20 (woman's age)
M = 60 (man's age)
Step-by-step explanation:
M = Man's age
W = Woman's age
M + 20 = 2(W + 20)
Sub for M
3W + 20 = 2W + 40
W = 20 (woman's age now)
M = 60 (man's age now)
