A store sold a case of scented candles for $17.85 that had been marked up 110%. What was the original price?

Salsk061 [2.6K]

$17.85 is 110% of the original price.

To find 1% divide this by 110:

17.85/110 = 0.16% (rounded).

Original price is 100% so 0.16*100 = $16.23 (rounded).

Check:

$16.23*1.1=$17.85 (1.1 is decimal equivalent of 110%).

The points (-6,-4) and (3,5) are the endpoints of the diameter of a circle. Find the length of the radius of the circle.

Bond [772]

Answer:

40.5

Step-by-step explanation:

diameter^2 = (3 +6)^2 + (5+4)^2

or, d^2 = 9^2 + 9^2

or, d^2 = 81 +81

or,d^2 =162

or d=√ 162

• d= 81

then radius = d/2

r = 81/2

•r= 40.5 ans

Okay, Once Again The Value Of X Has Been Lost & It's Up To You To Find It.
$- \frac{1}{2} (x + 4) = 16$
1st. Divide Both Sides By -1/2, Dividing By -1/2 Is The Same As Multiplying By -2
$\frac{ - \frac{1}{2}(x + 4) }{ - \frac{1}{2} } = \frac{16}{ - \frac{1}{2} } \\$
2nd. Subtract 4 From Both Sides
$x + 4 = - 32$
$x + (4 - 4) = - 32 - 4$
3rd. Divide By The Coefficient Of X
$\frac{(1)x}{1} = \frac{ - 36}{1}$
4th.
$x = - 36$

The 3rd Step Is Technically Not Needed, Because We Know The Coefficient Of X In The Equation Is 1, If It Was Any Other Value, Then It's Needed.
