Answer:$90

Step-by-step explanation: $30 is the cost. 200 is the percent of Mark-up, so you take 100 percent of 30 and add it together then you get 60. Repeat that step for a total of 90. 100 percent of 30 is 30. So 30+ 30+ 30 = 90.

Factor completly x^2 -64

Hoochie [10]

∑ Hey, jillianwagler ⊃

Answer:

$\left(x+8\right)\left(x-8\right)$

Step-by-step explanation:

<u><em>⇒ Given info:</em></u>

<em>Factor completely </em> $x^2 -64$

<u><em>⇒ Solution:</em></u>

<em>Rewrite 64 as 8 ² because 8² is equal to 64. 8 ² = 8 × 8 = 64.</em>

<em /> $=x^2-8^2$

Applying difference of two squares formula: $x^2-y^2=\left(x+y\right)\left(x-y\right)$

$=x^2-8^2=\left(x+8\right)\left(x-8\right)\\$

$=\left(x+8\right)\left(x-8\right)$

Answer~: $\left(x+8\right)\left(x-8\right)$

Linear System, substitutional method<br><br> 5x+4y=32 <br> 9x-y=33<br><br> helppp

Pachacha [2.7K]

5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ <u>45x - 5y = 165</u>
      <u>41y</u> = <u>123</u>
   41 41
      y = 3
      5x + 4(3) = 32
      5x + 12 = 32
   <u> - 12 - 12</u>
      <u>5x</u> = <u>20</u>
       5     5
      x = 4
      (x, y) = (4, 3)
