Answer:
Ten times a number minus 3 is greater than three times the number plus eleven
Step-by-step explanation:
we have the inequality
10x-3 > 3x+11
Let
x ----> a number
As a word problem will be
10x -----> Ten times a number x
+ ----> plus
-3 -----> negative 3
> greater than
3x ----> three times a number x
11 ----> eleven
therefore
Ten times a number minus 3 is greater than three times the number plus eleven
Okay to the first number in the ordered pair is the x and the second is the y. So (x,y) when you put a dot on the coordinate plane such as (2,3), you have to go the the horizontal line which is x and go over right 2 spaces(depending on how many numbers is one space) then go up 3. Do that same thing for each of the order pairs. Eventually you will have 4 dots. Connect those dots then you will have the quadrilateral. I hope this helps you!

Answer:
perimeter = 6x + 15
Step-by-step explanation:
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
We were told that the bottom of the triangle is x units.
From the diagram perimeter 4x + 12 + x + 3 + x = 6x + 15
Four times the length of the bottom will be 4x .
12 more than 4 times the bottom will be 4x + 12.
Hence another side of the triangle is 4x + 12.
Finally we were told that the last side is 3 more than the bottom, that will be x + 3.
Answer:
2.5mph
Step-by-step explanation:
S = Distance divided by Time (S = D/T)
Therefore.
S = 15/6
=2.5 mph
Colin walked an average speed of 2.5mph
