Upon formation of an equation from a given pattern, we know how the variables in the patter are related. Using the equation, we can find the value of one of the missing variables if the rest are known and also predict the values of the pattern at given conditions.
An example:
y = 2x + 5
if we are to predict the value of y at x = 3, we simply substitute 3 into x
y = 2(3) + 5
= 11
Let x be the original amount as per the ques tion (7/6) x= 420thus x=420*6/7=360thus the interest earned is 420 -360=60
Answer:
12 20 15
Step-by-step explanation:
We can simplify 15/3 to 5.
N/6 = 5. Then multiply both sides of the equation by 6, giving us N = 30.
Answer:
A
