Make the fractions improper to multiply.2 1/5 becomes 11/5 and 1 3/4 becomes 7/4. multiply the numerators then multiply the denominators. you get 77/20, which is simplest form. don't let teachers feed you that bs about it having to be a mixed number. an improper fraction is way more useful.
Answer:

Step-by-step explanation:




Answer:
C
Step-by-step explanation:
Check all points:
A: x=0, y=10, then from the equality
follows that A lies on the line.
B: x=3, y=13, then from the equality
follows that B lies on the line.
C: x=8, y=2, then from the inequality
follows that C doesn't lie on the line.
D: x=5, y=15, then from the equality
follows that D lies on the line.
Answer:
4 1/15 simpilied MIGHT BE WRONG
Step-by-step explanation:
Answer:
1) x = 17, line a parallel to line b
2) x = 18, line a parallel to line b
Step-by-step explanation:
If line a parallel to line b then (10x - 40) + 50 = 180
Solve for x
10x - 40 + 50 = 180
Combine like terms
10x + 10 = 180
10x = 170
x = 17
x = 17, line a parallel to line b
-------------------------------------------------
If line a parallel to line b then 5x - 16 = 74
Solve for x
5x - 16 = 74
5x = 90
x = 18
x = 18, line a parallel to line b
