Roman has 20 pencils in his backpack. If this is 25% of the total number of pencils, how many pencils are in his backpack? Explain.

5 pencils are in his packpack

Step-by-step explanation:

so basically he has 20 penicls and only 25 percent is in so basically 5 10 15 20 I MIGHT BE WRONG

He has 80 pencils

Step-by-step explanation:

Let p = pencils

25% of the total pencils are in the backpack

That number is 20

p*25% = 20

Changing to decimal form

.25p = 20

Divide each side by .25

.25p/.25 = 20/.25

p = 80

He has 80 pencils

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

they used 313 gallons of paint
