Helps you learn mathematical concepts, such as the four basic arithmetical operations and finding divisors.
Answer:
Currently, Alex is 32 years old. His son is 8 years old,
Solution: denote the age of Alex’s son as ‘x’. Alex’s age is 4x
In 16 years, Alex’s age will be 4x + 16. His son’s age will be x + 16
4x + 16 = 2(x+16). solving this equation yields:
4x + 16 = 2x + 32. Grouping like terms algebraically gives: 2x = 16
Thus x = 16/2 = 8. 4(8) = 32
Add -11 and 15 to get 4
x^2 + 4
Answer:Step-by-step explanation:
The sine of 35 degrees = x / 15
x = sine (35) * 15
x = 0.57358 * 15
x = 8.6037
