Answer:
$356.00
Step-by-step explanation:
If d represents the discounted price, and p is the original price, you have ...
d = p - 20% × p = p(1 -20%) = 0.80p
Then the original price is ...
p = d/0.80 . . . . . divide by the coefficient of p
p = $284.80/0.80 = $356.00
The price before the discount was $356.00.
Answer:
2x + 3y = 12 Is the standard form for linear equations. To determine the slope, solve the equation for y in order to convert to the slope - intercept from7 y = mx + b where is m the slop and b is the y - intercept.
2x + 3y = 12
subtract 2x from both sides.
3y = -2x + 12
Divide both sides by 3.
y= - 2/3 x + 12/3 =
y= - 2/3x + 4
The slope is - 2/3
Answer:
32
Step-by-step explanation:
The sequence is going six numbers up each time. For example 2 plus six is 8. 8 plus six is 14. 14 plus six is 20 and so on.
It’s B actually :) hope this helps
Answer:
Step-by-step explanation:
Problem One
(n - 2)*180 means that you take the number of sides and subtract 2. Then you multiply by 180. Read this next part carefully. What you have is the number of degrees that the quadrilateral equals for its interior angles.
The total of the interior angles = (4 - 2)*180
The total of the interior angles = 2 * 180
The total of the interior angles = 360
90 + 90 + 4x + 14 + 5x + 23 = 360 Collect the like terms
9x + 217 = 360 Subtract 217 from both sides
9x = 143 Divide by 9
x = 15.89
Two
You are now trying to find the sum of the interior angles of a hexagon.
(n - 2)*180/6 = (6 - 2)*180/6 = 4 * 30 = 120
This is a little different. What you have found is 1 angle of a regular hexagon. It is 120 degrees.
6x - 26 = 120 Add 26 to both sides
6x = 120+26 Combine
6x = 146 Divide by 6
x = 146/6
x = 23.333333
