2a + 9 = 4a - 19

2a - 4a = -19 - 9

-2a = -28

a = -28/-2

a = 14

<u>Algebra I</u>

  • Coordinates (x, y)
  • Terms/Coefficients
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = x + 8

x + y = 2

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y </em>[2nd Equation]:                                                                         x + x + 8 = 2
  2. Combine like terms:                                                                                         2x + 8 = 2
  3. [Subtraction Property of Equality] Subtract 8 on both sides:                        2x = -6
  4. [Division Property of Equality] Divide 2 on both sides:                                  x = -3

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Substitute in <em>x</em> [1st Equation]:                                                                           y = -3 + 8
  2. Add:                                                                                                                   y = 5

Single discount rate equavalent to a series of discounts 20% and 25% is
zhenek [66]

Answer:

The single discount rate equavalent is a discount of 40%.

Step-by-step explanation:

The multiplier for a increase of a% is 1 + a/100.

The multiplier for a decrease of b% is 1 - b/100.

Discount of 20%:

20% decrease:

1 - (20/100) = 1 - 0.2 = 0.8

Discount of 25%:

1 - (25/100) = 1 - 0.25 = 0.75

Series of discounts(20% and 25%):

0.8*0.75 = 0.6

1 - 0.6 = 0.4

The single discount rate equavalent is a discount of 40%.
