To solve this problem we can use simple proportion
If
270$ -------------------------3000 pesos
x $ ---------------------------100 pesos (x$ means that we dont know how much)
Now we crossmultiplying to get proportion
x*3000=270*100
Now we just to solve eq
3000x=27000 /:3000
x=27000:3000
x=9$ - its the result
Answer:
11
Step-by-step explanation:
Area = LW
We know that the w = 2
We are told that the L (length) is three less than an unknown number so that mean L = (x - 3)
We are then told that the area = 22 square inches.
Area = LW
22 = (x - 3)2
Now solve for x
22 = (x - 3)2
Distribute the 2
22 = 2x - 6
22 + 6 = 2x
28 = 2x
28 / 2 = 2x / 2
14 = x
x = 14
Now take 14 and subtract 3
14 - 3 = 11
Unknown number = 11
Area = LW
L = 11
W = 2
Area = 22
11 * 2 = 22

(F)=6+3F
We move all terms to the left:
(F)-(6+3F)=0
We add all the numbers together, and all the variables
F-(3F+6)=0
We get rid of parentheses
F-3F-6=0
We add all the numbers together, and all the variables
-2F-6=0
We move all terms containing F to the left, all other terms to the right
-2F=6
F=6/-2
F=-3
I don’t know if it is right but I hope this helps :)
