11-2r+3=4 first subtract 11 and 3 from both sides of the equation, so the equation looks like this:

-2r=-10 next, divide both sides by -2

r=5.

Sally either walks, cycles or drives to work. She walks about 15% of the time and drives about 3/5 of the time. What percentage

goblinko [34]

Answer: She cycles 25% of the time

Step-by-step explanation:

From the question, Sally walks 15% of the time.

She drives 3/5 of the time.

We then convert 3/5 to percentage.

Converting to percentage means multiplying by a factor of 100.

Hence, Sally drives 3/5*100 = 60% of the time.

If Sally walks 15% of the time and drives 60% of the time, adding up the percentage time used by these two media of transportation will give us

60% + 15% = 75%

Hence if she cycles for the remainder of the time, expressing it as percentage would mean subtracting the time used in other means by 100%

Hence it will be 100% - 75% = 25%
