You can use a bar graph or histogram to compare amounts of items You can also draw arrays to help with multiplication problems.
In algebra, you can graph equations to see points of sets.
Hope this helps!
Answer:
Yes, y=5x is a direct variation and the constant of variation is 5 .
Use the foil method to multiply out the expressions. Then solve for x by first combining like terms and then using inverse properties
Answer:
x=2
Step-by-step explanation:
8 + x = 4x +2
Subtract 4x from both sides:
8 + x - 4x = 4x + 2 - 4x
Group like terms:
x - 4x + 8 = 4x + 2 -4x
Simplify the arithmetic:
-3x + 8 = 4x + 2 -4x
Group like terms:
-3 + 8 = 4x - 4x + 2
Simplify the arithmetic:
-3x + 8 = 2
The two do not save money at the same rate, because if you make common denominators of 20, Anna saves 6 dollars for every 20, while Patrick only saves 5 dollars for every twenty earned. So, Anna ends up saving more than Patrick.
