If the crew members used 3 gal of paint per hour and bought 30 gal of paint for a job, then they will work 30:3=10 hours.

  1. They start at x=0 hours with y=30 gal of paint;
  2. They end at x=10 hours with y=0 gal of paint (they worked until they used all the paint).
  3. The dependence between x and y is linear.

Conclusion: the only possible sketch is A.

Answer: correct choice is A.

Solve 3(x-5)=18<br><br> 10 points help plz
mestny [16]

Answer:

x=1

Step-by-step explanation:

To solve this question we will have to open the bracket first

So let's solve

3(x-5)=18

Open the bracket

3x-15=18

Add 15 to both sides

3x=3

Make x the subject of formula by dividing both sides by 3

x=1

What is 9/10 minus 1/3
zavuch27 [327]
To combine the two fractions, you would have to make the denominators the same.

9/10 turns into 27/30  and 1/3 turns into 10/30
27 - 10 = 17

The answer would be 17/30

Can someone help me with number 9 please? thanks
Zina [86]
Each of the 223 million people put $10 back into circulation every year.

\sf 223,000,000\times 10=2,230,000,000

So every year, this much money goes into circulation, and this is how much that goes into circulation the first year.

\sf 2,230,000,000+2,230,000,000=4,460,000,000

This is how much that will be in circulation after 2 years.

\sf 4,460,000,000+2,230,000,000=6,690,000,000

This is how much that will be in circulation after 3 years.

So we can create the table:

\sf\left[\begin{array}{cc}\sf Years&\sf Money&\sf 1&\sf 2,230,000,000\\\sf 2&\sf 4,460,000,000&\sf 3&\sf 6,690,000,000\end{array}\right]

What happed here is that what you can preddict is that, a aprediction.

In real life things not always will follow probabilities tables.

If you have two heterygous parents, you have a possibilie based on two alleles fot the same characteristic.
