Alright, first thing's first, simplify the equation as much as you can. If you wanted, I suppose you could just multiply everything by 40, but that's super unconventional.
7x/8 - 3x/8 = 1/5 + 3/10
Simplify:
4x/8 = 1/5 + 3/10
Make sure that when subtracting or adding fractions that the denominators (The number on the bottom of the fraction) are equal.
In order to add 1/5 and 3/10 together, all we have to do is ensure that both denominators are equal.
To do this, simply multiply 1/5 by 2/2. The new fraction will be 2/10 (You can do this since it's the exact same fraction, 2/10 will simplify down to 1/5. The reason we did this was to make sure that the two fractions had equal denominators).
Our equation now looks like this:
4x/8 = 2/10 + 3/10
Add the fractions on the right:
4x/8 = 5/10
Huh, whaddya know? Both the fraction on the left and the right can be simplified into 1/2! (4/8 becomes 1/2, and 5/10 becomes 1/2)
1x/2 = 1/2
x/2 = 1/2
If you want to, I suppose you could cross multiply to check, but the answer's already pretty obvious.
x = 1
Good luck! If you need me to explain anything I did here, just ask :))

2 - 4 * 5p + 1
Simplified, this equation looks like this:
4 * 5p = 20p
2 - 1 = 1
20p + 1 is the simplified form of this equation.
Answer:
there is a 0.02 or 2% difference
Answer:
8
inches
Step-by-step explanation:
Let l represent the length of the square
The area of a square = l^2
That means,
l^2 = 24 km^2
Take the square root of both sides
l = 
l = 
l = 
l = 2
Now lets find the perimeter
Perimeter of a square, P = 4l
P = 4* 2
P = 8 inches
20 weeks
The initial equation is 25x+150=650. Since she already has 150, we can subtract that from the total to get 500. We now have that 25x=500. Divide by 25 on both sides to get 20 weeks
