What is the solution to (5d+8)=3(8-d)

Mathematics
1 answer:
nekit [7.7K]3 years ago
8 0

Answer:

d=2

Step-by-step explanation:

We can simplify both sides, by removing both parentheses, and using the distributive property on the other side.

5d+8=24-3d

Next, we add 3d to both sides, like so:

8d+8=24

Then we can subtract 8 from both sides, then simplify for d.

8d=16

d=2

For an outdoor concert by the city​ orchestra, concert organizers estimate that 19 comma 000 people will attend if it is not rai
My name is Ann [436]
<h2>Answer:</h2><h2>The expected number of people who will attend this concert = 2260</h2>

Step-by-step explanation:

The concert organizers estimate people will attend if it is not raining = 19000

If its raining people will attend = 4000

On the day of the​ concert, meteorologists predict a 90​% chance of rain.

This means 10 % chance of not raining

The expected number of people = 90% (4000) + 10% (19000)

   = 360 + 1900

  = 2260

The expected number of people who will attend this concert = 2260

Tobias's music store bought a piano at the wholesale price of $550. Tobias marked up the price 35%. What was the amount of marku
Mrrafil [7]

Answer:

A.  $58.50

B.  $80

C.  No. The markup was 33 1/3%

Step-by-step explanation:

You are expected to know the relevant relationship is ...

  cost + markup = selling price . . . . also called "store price" in this problem

___

A. The markup is 30% × $45 = $13.50, so the store price is ...

 $45 + 13.50 = $58.50

___

B. When the 30% markup is added to the 100% cost, the selling price is 130% of the cost, or 1.30 times the cost. Here you have ...

 $104 = 1.30 × cost

 $104/1.3 = cost = $80 . . . . . divide by the coefficient of cost

___

C. The markup is $100 -75 = $25, so the markup percentage based on cost is ...

 $25/$75 × 100% = 33 1/3%

This is not 30%.
