I can't see pictures, but to find the area of a triangle, you multiply the dimensions, as you would a rectangle, but divide the area by 2.
For example, the dimensions of a triangle are 4 and 6.
Multiply the two.
4x6=24.
But don't stop there. Divide 24 by 2.
24/2=12.
So the area of the example triangle is 12.

Let Gavin be G
Let Seiji be S
G + S = 425
G = 25 + S
I can't really graph, but plug in some numbers to G and S that works in BOTH equations. Then graph it.
G + S = 425
G = 25 + S
(25 + S) + S = 425
2S + 25 = 425
2S + 25 (-25) = 425 (-25)
2S = 400
2S/2 = 400/2
S = 200
Seiji made 200 dollars
Now choose one of the equations to use (the easier the better) in this case i will choose this one:
G = 25 + S
pug in 200 into S (because that is how much Seiji made)
G = 25 + (200)
G = 225
Seiji made 200, Gavin made 225
200 + 225 = 425, which is the total amount the made

Answer:

Step-by-step explanation:

If you want to solve this easily, you can just remove x and add 30x + 60x.

We know that 30 + 60 is 90. So we will add x to 90.

Now you have your answer!
Hope this helps!

.
Answer:
14.2%
Step-by-step explanation:
1. Find the new cost for Stock A:
2000x0.88=1760
2. Find the new cost for Stock B:
5720x0.85=4862
3. Find total sum of the original stocks:
2000+5720=7720
4. Find total sum of the new stocks:
1760+4862=6622
5. Find the decrease:
7720(1-x)=6622
Solve for x
x=14.2
