Answer:
f=60 , c=30
Step-by-step explanation:
there are 2f and 2c in the graph and f=2c
So
f+f+c+c=180
2c+2c+c+c=180
6c=180
c=180/6
c=30
f=2c
f=2×30
f=60

Answer:
The smaller number can be 8 or
.
Step-by-step explanation:
Consider the provided information.
let the larger number is x and the smaller number is y
A positive number is 3 times another number.

If we add 2 to the larger and 5 to the smaller, then one of them becomes 2 times the other.
Case I: If 2nd number is 2 times to the first number.

Substitute the value of x.


Now substitute the value of y in 


Therefore, the smaller number is 8.
Case II: If 1st number is 2 times to the second number.

Substitute the value of x.




Therefore, the smaller number is
.
Answer:
The original cost was 20 dollars.
Step-by-step explanation:
$12 represents 60% of the original price.
Set up a proportion
Cross multiply Reduce 100/100 to 1
60/100 * x = 12 * 100/100
Multiply by 100
60/ 100 * x = 12
Divide by 60
60x = 12*100
60x = 1200
60x/60 = 1200/60
x = 20 dollars.
