162.15 is the answer because you have to multiply 0.15•141 then add 21.15 to the 141 :)
Answer:
y =-3000x +12000
Step-by-step explanation:
answer is
1) 12000 is the constant therefore when the number of hours is 0 the tickets are 12000
2) the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000 (negative because it is reducing)
Here is the equation:

Since 4 is next to the parentheses, you have to multiply everything in the parentheses by 4.
First multiply 3x by 4:

Now multiply 2 by 4:

Now add them together:

Your answer is <u>12x + 8</u>
Answer:
2,250 miles per day.
Step-by-step explanation:
John runs 2.5 miles per day. In a period of 30 months, you can averagely take 30 days in each month.
So, 30 x 30 = 900 days in 30 months.
To find the number of miles ran in 900 days,
900 x 2.5 = 2,250 miles per day.
Hope this helps.

- <em>You would need fewer the unit</em><em><u> </u></em><u>kilometer (km) </u><em>to measure a tree.</em>
Explanation:
In the internet you can find that the greatest height of a tree is aobut 115 meters.
Thus, you would never expect to find a tree measuring kilometers or miles.
If you used kilometers as unit, the measure of the tallest tree woul be about 0.115 km (115 meter divided by 1,000).
Most of the trees meausre in the range of 1 to 20 meters. That would be 0.001 km to 0.020 km.
Thus, kilometer is not a unit that you would need to measure a tree. You'd rather use centimeters, when the tree is small, and meters for most of the trees. You may also use feet, since 1 meter is about 3.28 feet, or even yards, since 1 yard is equal to 3 feet.
