Answer
kiran's aunt is 17 years older than Kiran. How old will Kiran's aunt be when Kiran is: 15 years old? 30 years old? years old? How old will Kiran be when his aunt ...
Step-by-step explanation:
The answer would be an odd number, 111.
Simplifying
5(7x + -3) = 230
Reorder the terms:
5(-3 + 7x) = 230
(-3 * 5 + 7x * 5) = 230
(-15 + 35x) = 230
Solving
-15 + 35x = 230
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '15' to each side of the equation.
-15 + 15 + 35x = 230 + 15
Combine like terms: -15 + 15 = 0
0 + 35x = 230 + 15
35x = 230 + 15
Combine like terms: 230 + 15 = 245
35x = 245
Divide each side by '35'.
x = 7
Simplifying
x = 7
A. f(1) = 1 + 3 = 4
b. f(6) = 2*6 = 12
The second one: 4 times 10 to the power of 12
