Answer: x/2+5 years old
Step-by-step explanation:
His sister would be x/2+5 years old. x/2 is his sisters age right now, and +5 is years later!
5x + 3 ≥ 10
3 is adding on the left, then it will subtract on the right
5x ≥ 10 -3
5x ≥ 7
5 is multiplying on the left, then it will divide on the right
x ≥ 7/5
x ≥ 1.4
Then, the smallest integer value of x is 2
400,000+90,000+2,000+0+30+02=492,032 is the answer put that and you will get a good grade :)
