Pleas please help! Solve for d. 3/15 - d/5 = 5/6 + d/3

Answers

Answer 1

Answer: $(3)/(15)$ - $(d)/(5)$ -( $(5)/(6)$ + $(d)/(3)$ =0

Step 1: $(5)/(6)$ + $(d)/(3)$ = $(3)/(15)- (d)/(5)- ((2d+5))/(6)=0$

Step 2: $(1)/(5)- (d)/(5)= ((1-d))/(5)- ((2d+5))/(6)=0$

Step 3: $((1-d)*6-(2d+5)*5)/(30)= (-1*(16d+19))/(30)$

Step 4: $16d= -19:Divide \ both \ sides \ by \ 16:d= (-19)/(16)= -1.188$

Your answer is $d\boxed{\boxed={ (-19)/(16)= -1.1888}}}}$

Answer 2

Answer: 3/15 -(d/5)=5/6+(d/3)
-(d/5)-(d/3)=5/6-3/15

-(8d/15)=19/30
-8d=19/2
-d=76
d=-76

Ed is a car salesman. he makes 1.5% commission on each car he sells. if he made $397.50 on the last car he sold,find the sales price of the car.

Answers

Answer:

$26,500.

Step-by-step explanation:

It is given that Ed is a car salesman. he makes 1.5% commission on each car he sells.

He made $397.50 on the last car he sold.

We need to find the sales price of the car.

Let x be the selling price of the car.

1.5% of x = $397.50

$x* (1.5)/(100)=397.50$

$0.015x=397.50$

Divide both sides by 0.015.

$x=(397.50)/(0.015)$

$x=26,500$

Therefore, the sales price of the car is $26,500.

(a) What is the probability that you roll a 6? Explain your reasoning.
(b) What is the probability that you either roll a 6 or do not roll a 6? Explain your reasoning.
(c) What is the probability that you don't roll a 6? Explain your reasoning.
Answer.

Answers

Answer:

(a) What is the probability that you roll a 6?

1/6

(b) What is the probability that you either roll a 6 or do not roll a 6?

5/6

Step-by-step explanation:

(a) What is the probability that you roll a 6?

In a 6- sided cube, a 6 occurs only once. That is only one face is labelled 6. Therefore, the probability that you roll a 6 is;

(number of faces labelled 6)/(totals number of sides) = 1/6

(b) What is the probability that you either roll a 6 or do not roll a 6?

The probability of rolling a 6 was found to be, 1/6.

On the other hand, the probability of not rolling a 6 is;

(number of faces not labelled 6)/(totals number of sides) = 5/6

Therefore, the probability that you either roll a 6 or do not roll a 6 is;

1/6 + 5/6 = 1

These two events are mutually exclusive and exhaustive.

The probability of not rolling a 6 is;

(number of faces not labelled 6)/(totals number of sides) = 5/6

We have 5 faces not labelled 6 out of 6 possible faces or outcomes

Find the product of 2/3x4/7x14/5

Answers

To multiply fractions, the numerator of the product is the product of the numerators, likewise for the denominators. (2/3) x (4/7) x (14/5) = (2 x 4 x14) / (3 x 7 x 5) = (112) / (105) = 1 and 1/15 .

$(2)/(3) * (4)/(7) * (14)/(5) \n \n = (2*4*14)/(3*7*5) \n \n = (112)/(105) \n \n \boxed{=1 (7)/(105) }$
