Answer:
Step-by-step explanation:
Given that:
x + 4y = 30
x - 2y = 0
Subtracting both equations:
6y = 30
y = 30/6
y = 5
Putting in above equation
x + 4(5) = 30
x + 20 = 30
x = 10

Step-by-step explanation:
Option B
48th term of arithmetic sequence is -152
<h3><u>
Solution:</u></h3>
Given that a arithmetic sequence has explict formula,

To find: 48th term of the arithmetic sequence
The nth term of arithmetic sequence can be found by substituting the required value of n in the explict formula
So 48th term of the arithmetic sequence can be found by substituting n = 48 in explict formula

Plug in n = 48

On solving we get,

Thus 48th term of arithmetic sequence is -152
