Solution to 3x-7y=19​

Mathematics
1 answer:
Troyanec [42]4 years ago
5 0

first move the variable to the right side

This causes it to change signs

3x=19+7y

Now you divide both sides by 3

X= 19/3 + 7/3y

This leaves you with your answer:

X= 19/3+7/3y

Hope this helps! :3

What is the median please help please help
Paladinen [302]

Answer:

54.5

Step-by-step explanation:

To find the median, first we have to put the numbers in ascending/increasing order.

43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set

36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.

The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.

36, 43, 50, 50,     51, 58,         59, 60, 69, 73

51 + 58 = 109

109/2 = 54.5

Write an equation for the nth term of each geometric sequence:<br>5, 10, 20, 40,​
Nataliya [291]

Answer:

a(n) = 5*2^(n-1)

Step-by-step explanation:

The nth term of a geometric series is given by the relation :

a(n) = ar^(n-1)

Where, a = first term ; r = common ratio ; a(n) = nth term of the series.

Given the series : 5, 10, 20, 40,​

First term, a = 5

Common ratio = a2/ a1 = a3/a2

Common ratio = 10/5 = 20/10

Common ratio = 2 = 2

Hence, nth term =

a(n) = 5*2^(n-1)
