To solve Systems of Equations you can use graphing, substitution, or by adding, subtraction, multiplying, or division methods. One solution is consistent and dependent. No solution is inconsistent. Infinitely many solutions is consistent and dependent.

For our class what I did was you can get the equation in slope-intercept form. Then plot the lines. If the lines meet then the point they meet at is the one solution. If they don't meet then there is no solution. If the equations are the same then there are infinite solutions. Before you comment with "that takes to long" like I know you will, I just did this for fun.<span />

Todd wants to buy a new video game for $43.31. He has $55.50. The sales tax is 8.5% of the total purchase. Does Todd have enough
sammy [17]

Answer:

  yes

Step-by-step explanation:

We can estimate* that the total price including tax of the game will be less than ...

  $43.31 +10% of 43.31 = $43.31 +4.33 = $47.61

Todd easily has enough to pay for the game, including tax.

_____

You can work this more exactly a couple of ways.

  1. Price + tax = 1.085×$43.31 = $46.99 . . . less than Todd's budget

  2. Most Todd can afford: $55.50/1.085 = $51.15 . . . more than the game price

_____

* For estimating purposes, we like to use numbers that are easy to compute with. 10% is one such number, as it only requires moving the decimal point.

The area of a triangle is 56.4cm and the base is 12cm.What is the height of the triangle?
ale4655 [162]

area of a triangle = 1/2 base x height

56.4 = 1/2 x 12 x height

56.4 = 6 x height

height = 56.4 /6 = 9.4cm
