Answer:
If what I think youre saying is correct, then it should be 1/9
Step-by-step explanation:
4/15 + (-7/45)
Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.
12/45 + (-7/45)
As the fraction on the right side is negative, it is taken away from the left fraction, hence:
(12 - 7)/45
Therefore, with simple subtraction,
5/45
Simplify to 1/9

Answer:
SU = 15
Step-by-step explanation:
Given that,
Point T is on line segment SU. So,
SU = ST + TU
Putting all the values, we get :
SU = 12 + 3
SU = 15
Hence, the length of SU is 15 units.
