Step-by-step explanation:

area of base= 1/2 * 8 * 6.9 = 27.6

area of lateral face= 1/2 * 8 * 14 = 56

total surface area = 27.6 + 56 + 56 + 56 = 195.6

A candle shop sells scented candles for $16 each and unscented candles for $10 each.The shop sells 28 candles today and makes $4
fredd [130]
The number of scented candles ... x
the number of unscented candles ... y

x + y = 28
$16 * x + $10 * y = $400  ... 16 * x + 10 * y = 400

If you would like to know how many scented and how many unscented candles did the shop sell today, you can calculate this using the following steps:

x + y = 28 ... x = 28 - y
16 * x + 10 * y = 400
____________________
16 * (28 - y) + 10 * y = 400
16 * 28 - 16 * y + 10 * y = 400
448 - 400 = 16 * y - 10 * y
48 = 6 * y    /6
y = 48 / 6
y = 8

x = 28 - y = 28 - 8 = 20

Result: The candle shop sold 20 scented candles and 8 unscented candles today.

Answer with detail please<br> -17= -3 - 2n<br><br> 54= 17n- (-3)
Sidana [21]

We need to find the value of n in the first equation, so you would do:

- 17 = -3 - 2n

Add 3 to both sides to cancel the -3 in the side of the n variable

- 14 = -2n

Next divide to get rid of the -2 because it is multiplied by the -2

7 = n

54 = 17n - (-3)

Since you know that a negative times a negative transforms into a positive this is what it would look like:

54 = 17n + 3

Subtract 3

51 = 17n

Divide by 17 and n would be

n = 3
