3. y=112 this takes a lot of process of elimination so ill save you the paragraphs of numbers
second row - k³⁰/k¹⁴ - k¹⁶
third row - 12 ⁴⁵⁻²³ - 12²²
hope this helps
Answer:
for question two: 12
for question four: 1/3
for question six: 25.75 (rounded to two decimal places)
Answer:
6x+y=36
Step-by-step explanation:
6x - A rose is $6 and you do not know how many she will buy so you would put an "x" after that symbolizing how many she will buy.
y - Carnations cost $1 and the amount purchased is unknown so you would use "y". Because they cost 1 dollar, you will not need to add 1 in front of "y" because "y" by itself is already known as one variable.
36 - The total cost of the arrangement is ultimately going to be $36
This is an example
Your length of the rectangle is 2 times the width.
Let length = 2x
Let width = x
Now your area = 450m^2
2x.x = 450 ("." means multiply)
2x^2 = 450
Therefore x^2 = 225
Therefore x= 15
If your x=15 , then you know your width.
Length = 2x (2 x 15 = 30)
Therefore:
Length = 30m
Width = 15m
Hope that helped! :)
