Answer:
36 years old (jim)
Step-by-step explanation:
looks like a good ol' word problem!
first, if you don't know what to do, always assign variables
Jim's age: x+9
June's age: x
Alex's age: x-8
we know the sum of their ages which is 82
so, x+9+x+x-8=82
simplify
3x+1=82
3x=81
x=27, but we're not done yet
Now we know x
jim: 36
june: 27
Alex: 21
so the oldest is jim at 36
Answer:
The equation is 21x+4y<3150
Step-by-step explanation:
This question can be understood by the concept of inequalities.
Let x be the number of stocks of software company and y be the number of stocks of robotics company purchased.
Money invested in 1 stock of software company = $42
Money invested in 1 stock of robotics company = $8
Total expenditure on software company stock = 42*x
Total expenditure on robotics company stock = 8*y
So the total expenditure should be less than 6300
Hence the equation is
42x+8y<6300
21x+4y<3150

For this case you could write a generic linear equation that determines the value in dollars after a number of years corresponding to the interval [0, 9]. Writing the equation we have
y = a * t + b with t [0, 9]
where,
a and b with constants that belong to the real numbers
t: it's time in years
y: the value in dollars of the mri machine.
answer:
y = a * t + b with t [0, 9]
Answer:
The smallest angle is 27 degrees.
Step-by-step explanation:
The interior angles of a triangle add up to 180.
(2x + 1) + (3x - 3) + 9x = 180
14x - 2 = 180
14x = 182
x = 13
The three angles are 27, 36, and 117,
