Answer:
In Step 4, the inequality sign should be flipped.
Step-by-step explanation:
Whenever you multiply or divide both sides of an inequality by a negative number, you need to flip the inequality sign. So, in Step 4, when you divide both sides by -10, the sign should be flipped.
The final answer should be:

ALL yourr doing is just adding 8 and 36
y= 4\frac{1}{2} or y= 4.5
by 10 years it'll be 24439 but by 11 it'll be 25661 so it's technically 11 years
Answer:
Answer is √202 or 14.21267
Step-by-step explanation:
d^2=(4−(−7))2+(5−(−4))2
d^2=(11)2+(9)2√
d^2=121+81
d^2=2–√202
d= 12.21267
37.68 is the answer
