Ginger wants to fill her new swimming pool. She has two pumps; the larger pump takes 40 minutes to fill the pool, and the smalle

Talja [164]

As per the problem,

The larger pump takes 40 minutes to fill the pool.

The smaller one takes 60 minutes.

When both the pumps are working , let the time taken be x minutes , then we can write

$\frac{1}{x}=\frac{1}{40}+\frac{1}{60}\\ \\ \text{Make the denominator equal we get}\\ \\ \frac{1}{x}=\frac{1}{40}*\frac{60}{60}+\frac{1}{60}*\frac{40}{40}\\ \\ \frac{1}{x}=\frac{60}{2400}+\frac{40}{24000}\\ \\ \text{Simplify we get}\\ \\ \frac{1}{x}=\frac{60+40}{2400}\\ \\ \frac{1}{x}=\frac{100}{2400}\\ \\ \frac{1}{x}=\frac{1}{24}\\ \\ x=24\\$

Hence, when both the pumps works together, Time taken =24 minutes.

Y=4x -1 and 12x=3y+7

Yuki888 [10]

You didn't really ask a question, so I'm assuming you want to know if there are any solutions to BOTH equations.

Use the first equation to substitute 4x - 1 for y in the second equation:

12x = 3(4x - 1)+7
12x = 12x - 3 + 7
12x = 12x +4
0 = 4

The last equation is FALSE, indicating the system of two equations has no solution.
