A sink has two faucets: one for hot water and one for cold water. The sink can be filled by a cold water faucet in 3 minutes. If
iragen [17]

Answer: 6\ minutes

Step-by-step explanation:

You can use the following formula:

\frac{T}{A}+\frac{T}{B}=1

You can say that "T" is the time (in minutes) for both faucets working together, "A" is the time (in minutes) for cold water faucet working alone and "B" is the time (in minutes) for hot water faucet working alone.

Based on the data given in the exercise, you can identify that:

T=2\\A=3

Therefore, substituting these values into the formula and solving for "B", you get that this is:

\frac{2}{3}+\frac{2}{B}=1\\\\\frac{2}{B}=1-\frac{2}{3}\\\\\frac{2}{B}=\frac{1}{3}\\\\2=\frac{1}{3}B\\\\2*3=B\\\\B=6

What fractions are equivalent to 9/18
sergey [27]
Equivalent fractions are fractions that can be simplified down to the same thing.

For example, 9/18 can be simplified down to 1/2

So, 1/2, 3/6, 4/8, 5/10, 6/12, etc are all equivalent fractions because they too can be simplified down to 1/2

Help me out with number 8!!! I’m confused and I need this by tomorrow HELP PLEASE

We can use elimination for these set of systems.
First, we need to set up our variables.
Belts=b
Hats=h
Now, the situation is 6 belts and 8 hats for $140. The situation after is 9 belts and 6 hats for $132.
Let’s set up our system of equations.
6b+8h=140
9b+6h=132
We need to eliminate a variable. Since b has coefficients of 6 and 9, we can easily eliminate b by multiplying the top equation by 3 and the bottom by -2.
18b+24h=420
-18b-12h=-264
Now let’s add.
12h=156
Let’s divide to get h by itself.
156/12=13=h
So a hat costs $13. We need to put in 13 for one of the equations so we can find the cost of a belt.
9b+6(13)=132
9b+78=132
We need b by itself.
9b=54
54/9=6
Belts are $6
We can also use the first equation to check our answers.
6(6)+8(13)
36+104
140.
So, the price of a belt is $6 while the price of a hat is $13.
