Answer:
x=11/2
Step-by-step explanation:
First we can combine similar terms on the left side. 3x + x is 4x and 20-15 is 5
Now that we have combined them, we are left with 4x+5=27
Subtract 5 on both sides to cancel out the 5.
4x=22
Divide both sides by 4
x=22/4
Simplify
x=11/2
The equation relating the number of cars to the number of passengers is p = 4n
<em><u>Solution:</u></em>
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n
Answer:
5/8
Step-by-step explanation:
There are 8 sections, and 4 sections that are 1, and 1 pink section. So adding these up, we get 5/8.
Hope this helped! :)
Step-by-step explanation: To solve this absolute value inequality,
our goal is to get the absolute value by itself on one side of the inequality.
So start by adding 2 to both sides and we have 4|x + 5| ≤ 12.
Now divide both sides by 3 and we have |x + 5| ≤ 3.
Now the the absolute value is isolated, we can split this up.
The first inequality will look exactly like the one
we have right now except for the absolute value.
For the second one, we flip the sign and change the 3 to a negative.
So we have x + 5 ≤ 3 or x + 5 ≥ -3.
Solving each inequality from here, we have x ≤ -2 or x ≥ -8.
