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
X/6 + 4 = 15
First, subtract 4 to both sides:
x/6 = 11
Now multiply 6 to both sides:
x = 66
Answer:
the rhombus and square must be switched
Step-by-step explanation:
the square looks like a diamond because its tilted sideways
Answer:
C
Step-by-step explanation:
Question incomplete but,
x1 = 5
y1 = 1
m = m
using the formula,
y - y1 = m(x-x1)
y - 1 = m(x-5)
Therefore, the likely answer is C
Explanation
The model has the form
Where a=initial amount
y= final amount
K= growth rate constant
t= time
When 140 kg of substance is left after 7 hours, the formula can be remodeled to be.
Therefore, the first solution is
For part b we have 16 hours.
Thus, the answer is 36kg
