Answer:

<h2>160 is 20% of 800</h2>

Step-by-step explanation:

METHOD 1:

\begin{array}{ccc}100\%&-&800\\\\20\%&-&x\end{array}\qquad\text{cross multiply}\\\\\\100x=(20)(800)\qquad\text{divide both sides by 100}\\x=(20)(8)\\\boxed{x=160}

METHOD 2:

\begin{array}{cccc}100\%&-&800&\text{divide both sides by 5}\\\\100\%:5&-&800:5\\\\20\%&-&160\end{array}

METHOD 3:

p\%=\dfrac{p}{100}\\\\20\%=\dfrac{20}{100}=\dfrac{2}{10}=0.2\\\\20\%\ of\ 800\to0.2\cdot800=160

35) -5(6k + 3) - 8(8-4k) = -73
OLga [1]

Answer:

k = 3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • -5(6k+3)-8(8-4k)=-73
  • -5(6k) + (-5)(3) + (-8)(8) + (-8)(-4k) = -73
  • -30k-15-64+32k=-73
  • (-30k+32k)+(-15-64)=-73
  • 2k-79=-73

Step 2: Add 79 to both sides.

  • 2k - 79 + 79 = -73 + 79
  • 2k = 6

Step 3: Divide both sides by 2.

  • \frac{2k}2} = \frac{6}{2}
  • k = 3

What is the mean of 9,7,6,3,22,7,4,2
leonid [27]

Answer:

The mean of that group of numbers is 7.5.

Step-by-step explanation:

The mean of a set of numbers is the sum of the numbers divided by the how many numbers you have.

First you add all of the numbers together:

9 + 7 + 6 + 3 + 22 + 7 + 4 + 2 = 60

Divide this sum by how many numbers there are in the group -- 8

60 ÷ 8 = 7.5
