We start by using the distributive property to expand the terms 5(a-1) and 3(a+2). When we do, we obtain 5a-5 and 3a+6.

Putting those back into our equation, we have:

5a-5-15=3a+6+4

Next, we combine all of the constants on either side:

5a-20=3a+10

Finally, we want to get the variable a by itself on one side of the equation, so we perform the following steps to isolate it:

5a=3a+30 (Add 20 to both sides)
2a=30 (Subtract 3a from both sides)
a=30/2=15 (Divide both sides by 2 to isolate a)

So, we obtain our answer of a=15.

5(a-1) - 15 = 3(a+2) + 4
Open all parenthesis and distribute
5a - 5 - 15 = 3a + 6 + 4
Simplify
5a - 20 = 3a + 10
Add both sides by 20 and subtract both sides by 3a
2a = 30
a = 15

Set up and solve an equation of ratios.  Comparing shadow lengths, we get 100/6; comparing heights, we get x/8.  Set these two ratios equal to one another and solve the resulting equation for x:

100       x
----- = ------      Then 6x=800, and x = 800 feet^2 over 6 feet.  Your answer

100 up 100 flat 100 down meters
then return 100 up 100 flat 100 down


time required (distance/rate = time ) 200/100 + 200/120 + 200 / 150 = 5 hr

distance 600


distance / time = average speed = 600/5 = 120 m/s
