Answer:
x = -3
Step-by-step explanation:
<u>Step 1: Subtract 8 from both sides</u>
8 - 3x - 8 = 17 - 8
<em>-3x = 9</em>
<em />
<u>Step 2: Divide both sides by -3</u>
-3x / -3 = 9 / -3
<em>x = -3</em>
<em />
Answer: x = -3
£66 because 60/10=6 60+6= £66
Answer:
y + 7 = -1/4(x - 4)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = -1/4
Point (4, -7)
<u>Step 2: Write Function</u>
y + 7 = -1/4(x - 4)
In mathematics, mean average means to take the sum of all the numbers and divide the sum by the number of elements in the set.
Add up the numbers.
<span>21 + 23 + 25 + 25 + 26 + 28 + 28 + 28 + 31 + 33 = 268
Divide by the number of elements in the set. Which is 10.
268 / 10 = 26.8
So, the answer to this question is 26.8</span>
