How do you solve 5(x+4) = 3x + 23

Answers

Answer 1
Answer: 5(x+4) = 3x + 23 

 5x+20=3x+23 

5x-3x=23-20 

2x=3 

x=3/2
Answer 2
Answer: 5 (X + 4) = 3X + 23

5X + 20 = 3X + 23

5X - 3X = 23 - 20

2X = 3

X = 3/2

X = 1 1/2

A product costs $60 today. How much will the product cost in t days if the price is reduced by $4 a day

Answers

Answer:

C=60-4t

Step-by-step explanation:

A product costs $60 today.

The price is reduced by $4 a day, so

  • a product will cost $60 - $4 = $56 tomorrow;
  • a product will cost $56 - $4 = $52 after 2 days;
  • a product will cost $52 - $4 = $48 after 3 days;
  • and so on

The genaral formula for the price of the product after t days will be

C=60-4t

The most accurate way would be the fourth answer, because to estimate 66% of 47 you need to round both as closely as possible. 66% rounds closest to 2/3, and 47 is closest to 48
The last option is the most accurate. Here is how you can solve it:
1) Turn fractions into decimals 
     2/3 =0.666666667
     1/4 =0.25
     1/4 =0.25
     2/3 =0.666666667 

2) Multiply
    0.666666667 x 50 = 33.333333...
    0.25 x 48 = 12
    0.25 x 50 = 12.50
    0.666666667 x 48 = 32

3) To find what 66% of 47 is, you turn 66% into a decimal and multiply it by 47. 
     0.66 x 47 = 31.02

66% or 47 is 31.02  

2/3 x 48 equals 32, and since it is the closest to 31.02. Therefore, the last option is the best option.

The probability distribution for a game is shown in the table below.what is the probability of NOT winning a cash prize if the game is played on time?

A) 7/10
B) 1/5
C) 4/5
D) 3/10

Answers

Given:

It is given that

Probability of winning $ 0 = (3)/(10)

Probability of winning $ 100 = (1)/(5)

Probability of winning $ 200 = (1)/(10)

Probability of winning $ 500 = (2)/(5)

To find the probability of not winning a cash prize.

Explanation:

Not winning cash prize = winning $ 0

So,

Probability of not winning a cash prize

= Probability of winning $ 0

= (3)/(10)

Therefore,

The probability of not winning a cash prize is (3)/(10). Option D.
