Solve the equation for a. Show your work.
4a-14=7a-8
Answer:
a=-2
Step-by-step explanation:
4a-14=7a-8
Subtract 7a from both sides:
4a-14-7a=7a-8-7a
Group like terms:
4a-7a-14=7a-8-7a
Simplify the arithmetic:
-3a-14=7a-8-7a
Group like terms:
-3a-14=7a=-7a-7a-8
Simplify the arithmetic:
-3a-14=-8
Add 14 to both sides:
-3a-14+14=-8+14
Simplify the arithmetic:
-3a=-8+14
Simplify the arithmetic:
-3a=6
Divide both sides by-3:
Cancel out the negatives:
Simplify the fraction:
Simplify the signs:

The number of users of social media has increased significantly since the year 2001. In fact, the approximate number of users has tripled each year. It was reported that in 2005 there were 3 million users of social media.
a. Assuming that the number of users continues to triple each year, for the next three years, determine the number of users in 2006, 2007, and 2008.
b. Assume the trend in the numbers of users tripling each year was true for all years from 2001 to 2009. Complete the table below using 2005 as year 1 with 3 million as the number of users that year.
c. Given only the number of users in 2005 and the assumption that the number of users triples each year, how did you determine the number of users for years 2, 3, 4, and 5?
d. Given only the number of users in 2005 and the assumption that the number of users triples each year, how did you determine the number of users for years 0, −1, −2, and −3?
e. Write an equation to represent the number of users in millions, , for year , ≥ −3.
f. Using the context of the problem, explain whether or not the formula = 3t would work for finding the number of users in millions in year , for all ≤ 0.
g. Assume the total number of users continues to triple each year after 2009. Determine the number of users in 2012. Given that the world population at the end of 2011 was approximately 7 billion, is this assumption reasonable? Explain your reasoning.

a water pump can remove 80 gallons of water per hour. the machine is designed to start and run continuously for 12 hours. initially there are 1200 gallons of water in the tank. write a function to describe the amount of water left in the tank in terms of hours that the pump has run.
Answer:
w=1200-80h
Step-by-step explanation:
w=gallons of water left, h=hours running. If there are initially 1200 gallons of water, and it pumps out 80 gallons per hour, then 80*hour, subtracted from the intial 1200 will tell you how much water is left. Hope this helps!

Last week, Byron bought 5 containers of yogurt and spent $12.88 on other groceries.
This week Cassandra bought 3 containers of the same yogurt and spent $11.50 on other groceries. How much more money did Byron spend than Cassandra?
1. Let c represent the cost of one container of yogurt. Write
expressions to represent the amount spent by Byron and the
amount spent by Cassandra.
2. Write an expression to represent the difference by subtracting the
amount that Cassandra spent from the amount that Byron spe
nt.
Then complete the steps to simplify the expression.
3. What expression represents how much more money Byron spent
than Cassandra?
Please give answer and stepes for each number
The Answer is
Step-by-step explanation:
1=5x$12.88-3x$11.50
Answer:
1. Byron: 5c + 12.88. Cassandra: 3c+11.50.
2. (5c + 12.88) - (3c + 11.50).
3. Same as 2, I think. I can’t solve the actual expression because the cost of the yogurt is unknown, however the expression simplified is 2c + 1.38
Step-by-step explanation:
1. c is the cost of one container of yogurt. Writing 5c basically means 5xc and it works because Byron bought 5 containers. Cassandra bought 3, so it works the same way.
2. The cost of the yogurt is unknown, so you can’t just substract the total from the other one. Use parentheses that contain the exact same expression that represents the money spent.
3. Explained in the answer

Suppose 2 friends want to share 5 cookies evenly. Interpret the remainder in two different ways.
Answer:
1.) 4 Carriers
2.) 12 boxes
3.) 2 r1 or 2.5
Step-by-step explanation:
1.) 8X = 30
We get the equation 8X = 30 from the fact that there are 8 calculators in each carrier and there are X to hold the 30 calculators.
X = 30/8 = 3.75 = 4 carriers because we can't have portions of carriers
2.) 3X = 34
We get the equation 3X = 34 from the fact that there are 3 toys in each box and there are a total of X boxes to hold the 34 toys.
X = 34/3 = 11.3333 = 12 boxes because we can't have a third of a box
3.) Two friends can evenly share four cookies with one cookie leftover. two ways of dealing with this remainder are leaving it and neither for and gets any of the cookies or each friend gets half of the cookie.
written: 2 r1 or 2.5
