Solve the sum of two-fifths and f is one half

The sum of two-fifths and f is 1/2 can be represented by:

2/5+f=1/2

Then to solve for f an easier way would be turn the fractions into decimals to get:

0.4+f=0.5 (subtract 0.4 from both sides)

f=0.1 or 1/10

hope this helps mark brainliest if it does :)

1/10

Step-by-step explanation:

2/5 + f = 1/2

subtract two fifths from both sides

f = 1/10

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.
