(10x-20)= (6x+8) subtract 6 from each side
(4x-20)=(+8) add 20 to each side
(4x)=(28) divide both sides by 4
x= 7
6: I would pick D
1: D again
2: I would choose A
Hope this helps
If John bought 2 horses at 20,000 each, that means he spent $40,000 in total, because 2 x 20,000 is 40,000.
We can write it like this:

if x isn't 0, we can divide both sides by x:

and again

and now we can calcuate

and divide both sides by 4.
We're left with 9!!
so the solution is 9!
Answer:
B. 1728 cm²
Step-by-step explanation:
You have to find the area of each side:
Top side: 32*20=640
Bottom side: 16*32=512
Triangle sides: 1/2*12*16=96*2=192
Back side: 12*32=384
add all these up and you get 1728
