{(24p – 66) = 3p + 43

Alenkinab [10]

$\text {Hello! Let's Solve this Equation!}$

$\text {\underline {The First Step is to Subtract 3p}}$

$\text {24p-66-3p=3p+43-3p}$

$\text {Your New Problem Is: 21p-66=43}$

$\text {\underline {The Next Step Is to Add 66}}$

$\text {21p-66+66=43+66}$

$\text {Your New Problem Is: 21p=109}$

$\text {\underline {The Final Step is to Divide 21}}$

$\text {21p/21=109/21}$

$\text {Your Answer Would Be:}$

$\fbox {p=109/21}$

$\text {Best of Luck!}$

A cold-water faucet can fill a sink in 1212 min, and a hot-water faucet can fill it in 1515 min. The drain can empty the sink

sweet-ann [11.9K]

Answer:

9.1 minutes.

Step-by-step explanation:

Let t represent time taken to fill the tank.

We have been given that a cold water faucet can fill a sink in 12 min, so the part of sink filed in 1 minute would be $\frac{1}{12}$ .

The hot-water faucet can fill it in 15 min, so the part of sink filed in 1 minute would be $\frac{1}{15}$ .

The drain can empty the sink in 25 min, so the part of drain emptied in 1 minute would be $\frac{1}{25}$ .

The part of 1 full tank filled in t minutes, when both faucets are on and the drain is open would be:

$(\frac{1}{12}+\frac{1}{15}-\frac{1}{25})t=1$

Make a common denominator:

$(\frac{1*25}{12*25}+\frac{1*20}{15*20}-\frac{1*12}{25*12})t=1$

$(\frac{25}{300}+\frac{20}{300}-\frac{12}{300})t=1$

$(\frac{25+20-12}{300})t=1$

$\frac{33}{300}t=1$

$\frac{11}{100}t=1$

$\frac{100}{11}\times \frac{11}{100}t=\frac{100}{11}\times1$

$t=\frac{100}{11}$

$t=9.0909$

$t\approx 9.1$

Therefore, it will take 9.1 minutes to fill the sink.
