Ok so you subtract 8 from both sides and you get

13d = -9

Then you need to get d by itself
So divide both sides by 13

The answer should be about -0.69

d = -0.69

Answer:

Step-by-step explanation:

13d + 8 = -1

subtract 8 from both sides

13d = -9

d = -9/13

A furnace delivers 8.0 × 104 btu per hour. how many kilocalories per hour is this?
vazorg [7]
For this case the first thing you should know is the following unit conversion.
 1 BTU = 0.25 Kilocalories
 We then have the following numerical value:
 8.0 * 10 ^ 4 \frac{BTU}{h}
 Applying the conversion of units we have:
 8.0 * 10 ^ 4 \frac{BTU}{h} * 0.25 \frac{Kcal}{BTU}
 Canceling units we have:
 20000 \frac{Kcal}{h}
 Answer:
 
This is 20000 kilocalories per hour
 
20000 \frac{Kcal}{h}

At the ritz concert tickets for adults cost $6 and tickets for students cost $4. How many of each ticket were purchased if 480 t
Anni [7]

Answer: the number of adult tickets is 210

The number if student tickets is 270

Step-by-step explanation:

Let x represent the number of adult tickets that were purchased.

Let y represent the number of student tickets that were purchased.

At the ritz, concert tickets for adults cost $6 and tickets for students cost $4. If the cost of total tickets purchased is $2340, then,

6x + 4y = 2340 - - - - - - - -1

Total number of tickets purchased is 480. This means that

x + y = 480

x = 480 - y

Substituting x = 480 - y into equation 1, it becomes

6(480 - y) + 4y = 2340

2880 - 6y + 4y = 2340

- 6y + 4y = 2340 - 2880

-2y = - 540

y = - 540/-2 = 270

x = 480 - 270

x = 210
