.15 × 30.00 = 4.50
30.00 - 4.50 = 25.50
$25.50 is the sale price. I rounded 29.99 to 30.00
Answer:
x=2 and y=-1. The steps--
Step-by-step explanation:
<em>FIRST STEP: </em>SUBSTITUTE -4y with the definition in y=2x-5. This makes the first equation -3x-4(2x-5)=-2
<em>SECOND STEP: </em>DISTRIBUTE -4 throughout the parenthesis, making the equation -3x-8x+20=-2.
<em>LAST STEP: </em>SOLVE by combining like terms, -3x-8x, to make -11x, and subtracting 20 from each side, to make -11x=-22. Then divide both sides by -11, making x=2. From there, you solve that y=2(2)-5, solving that y=4-5, y=-1.
Therefore, x=2 and y=-1

Step-by-step explanation:
<u>Number of squares:</u>
- 1x1 squares = 8*8
- 2x2 squares = 7*7
- 3x3 squares = 6*6
- 4x4 squares = 5*5
- 5x5 squares = 4*4
- 6x6 squares = 3*3
- 7x7 squares = 2*2
- 8x8 square = 1
<u>Total number:</u>
- 8² + 7² + 6² + 5² + 4² + 3² + 2² + 1 =
- 64 + 49 + 36 + 25 + 16 + 9 + 4 + 1 =
