Answer: v > -21
Step-by-step explanation: To solve for <em>v</em> in this inequality, your goal is the same as it would be if you we're solving an equation, to get <em>v</em> by itself on one side.
Since 2 is being added to <em>v</em>, we subtract 2 from both sides of the inequality to get <em>v > -21</em><em>.</em>

Finally, make sure to write your answer in <em>set notation </em>as {v: v > -21}.
This means that any number greater than -21 is a solution to this inequality.
The correct answer here is 2/3
That is because 7 doubled is 14 and 7 multiplied by 3 is 21.
You have to add 103 to 228 which gives you 331. Answer 331 miles
Answer: 18 parent volunteers and 4 buses.
Step-by-step explanation: In order to solve this problem you must first calculate how many student will be going on the trip.
There are 8 classes of 20 students and 90% are attending, so the formula is 8 x 20 x .9 = 144 students are going.
Part A: If one parent needs to go for each 8 students you need to divide 144 by 8 = 18 parent volunteers.
Part B: The total people attending are 144 students, 18 parent volunteers and 4 teachers is a total 166 total attending to ride the bus. You need to divide 166 people by 44 on each bus = 166/44 = 3.7 buses, so they need to reserve 4 buses.
The expression is 60a + 30c.
In this expression you add the two numbers together. Since it is an expression you don't solve it
Hope this helps! :D
