J + t = 30
j = 2t - 3
2t - 3 + t = 30
3t - 3 = 30
3t = 30 + 3
3t = 33
t = 33/3
t = 11 <=== tritt's age is 11
j = 2t - 3
j = 2(11) - 3
j = 22 - 3
j = 19 <== jan's age is 19
The unknown number is n. So n is the unknown variable in the equation.
In order to write an equation in which n is included we must know some dependence of n with other values.
We know that <span>the difference of three times a number and 44 is −19. So, we can write:
3*n-44=-19
3*n=-19+44
3*n=25
n=25/3

The first 3 are correct but for the last one I’m not sure
The ratio of three numbers are 2:3:4.
Let the rational between the three numbers be x, hence the three numbers be 2x, 3x,and 4x.
If their average is 36, what are the numbers
We know the average = sum of the numbers / no. Of numbers.
(2x+3x+4x) /3=36
9x/ 3= 36
3x =36
X= 36/ 3
X= 12
The rational is 12
Answer the three number are 24, 36, and 48.
HOPE THIS HELP!!
