Answer:
0, Infinite Solutions
Step-by-step explanation:
First we distribute 5 to 8x and -4
40x - 20 - 10 = 40x - 20 - 10
Next, collect like terms
40x - 30 = 40x - 30
This equation has infinite solutions because on both sides of the equation the values are the same.
Just to check
Add 40x to both sides
-30 = -30
Add 30 to both sides
Then we get 0
4/5*9/10= 36/50 = 18/25
Just multiply the fractions straight across since area is length*height
Answer:
44m
Step-by-step explanation:
A = 
r² = 154
= 22/7 * r² = 154
= r² = 154 * 7/22
= r² = 49
= r = √49
= r = 7m
Perimeter of circle = 2r
= 2 * 22/7 * 7
= 44/7 * 7
= <u>44 m</u>

The key is Esther travelled the same distance - x - in both her morning and evening commute.
45(time she took in the morning, or p) = x
30(time she took in the evening, or q) = x
Therefore 45(p) = 30(q), or divide both sides by 5 and get 9(p) = 6(q). I know you can divide it further, but these numbers are small enough and it's not worth the time.
Since the whole trip took an hour, (p + q) = 60min, and so, p = 60-q.
Therefore 9(60-q) = 6q or 540-9q = 6q. So 540 = 15q, which makes q = 36. If q = 36, then by (p+q)=60, p (the time she took in the morning) must equal 24.
45 miles per hour, her speed in the morning, times (24/60) hours, her time, makes 18 miles travelled in the morning. If you check, 30 miles per hour times (36/60) hours also makes 18 miles in the evening.
