Answer:
Divide each term by −2 and simplify.
Inequality Form:
x>−5
Interval Notation:
(−5,∞)
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x=2
Step-by-step explanation:
14x+3=31
Step 1: Subtract 3 from both sides.
14x+3−3=31−3
14x=28
Step 2: Divide both sides by 14.
14x/14=28/14
x=2
Answer: There are 12 white and blue cars more than silver and red cars
Number of white cars: n1=25
Number of blue cars: n2=17
Number of white and blue cars: n3=n1+n2=25+17→n3=42
Number of silver cars: n4=21
Number of red cars: n5=9
Number of silver and red cars: n6=n4+n5=21+9→n6=30
How many more white and blue cars are there than silver and red cars?
n=?
n=n3-n6=42-30→n=12
Answer: There are 12 white and blue cars more than silver and red cars.
Answer:
B
Step-by-step explanation:
The slope of the line that passes through the given points is (4-7)/(-3-1) = 3/4.
Since parallel lines have equivalent slopes, the answer is B.
For this to find the median all you do is put the numbers in order from least to greatest. Is there is a odd amount of numbers then it is the number in the middle. If there is an even then you find the two numbers in the middle and do by .5
In this case there are an even amount of numbers. So..
Put the numbers in order.
-70,-64,64,66,70,73
So the two numbers in the middle are 64 and 66.
The median is: 65
