Answers

Answer 1

Answer:

a= -1

b= 3

c= -7

The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation they've given you to solve.

You have a bag with 6 green marbles, 15 blue marbles, 8 red marbles, 1 yellow
marble. What is the probability (as a decimal rounded to three places) of pulling
out a red marble?

Answers

Answer:

0.267 or 26.7%

Step-by-step explanation:

The probability of an event happening is calculated by dividing the favorable outcomes by all outcomes:

The sum of all events (marbles) is 6 + 15 + 8 + 1 = 30

The number of favorable events is 8

Therefore, the probability is 8/30 ≈ 0.267 or 26.7%

The sum of two numbers is 2490 and if 6.5 percent of one no. is equal to 8.5 percent of the other, then numbers are ?? Make sure it’s correct answer pls! 20 points for brainliest (also can u tell me how to mark someone brainliest?)

Answers

Answer:

The two number are :

x = 1411

y = 1079

Step-by-step explanation:

Let the two numbers = x and y

The sum of two numbers is 2490

x + y = 2490..... Equation 1

If 6.5 percent of one no. is equal to 8.5 percent of the other,

Hence:

6.5% of x = 8.5% of y

0.065x = 0.085y

Make x the subject of the Formula

x = 0.085y/0.065

x = 1.308y

We substitute 1.308y for x Equation 1

x + y = 2490..... Equation 1

1.308y + y = 2490

2.308y = 2490

y = 2490/2.308

y = 1078.8561525

y = 1079

x + y = 2490..... Equation 1

x = 2490 - y

x = 2490 - 1079

x = 1411

Hope this helps.

Answer:

Solution: (-1, -7)

Step-by-step explanation:

6x - 1 = 3x - 4

Subtract 3x from both sides;

3x - 1 = -4

Add 1 to both sides;

3x = -3

Divide both sides by 3;

x = -1

Substitute x into the equation;

y = 3(-1) - 4

y = -3 - 4

y = -7

8 True or False: The substitution method is a method of solving systems of equations by adding equations together in such a way that the variables are set aside, one by one.

Jayson buys a car and pays by installments. Each installment is $567 per month.
After 48 months, Jayson owes $1,250. What was the total price of the vehicle?

Answers

Answer:   $28,466

================================================

Explanation:

Each installment or payment is $567 per month.

If 48 months go by, then Jayson has paid 48*567 = 27,216 dollars.

If he still owes $1250, then this means he will pay back a total of 27,216+1,250 = 28,466 dollars.

Buckeye truck rentals has a daily rate of $59.99 plus $0.34/mile. Goodyear truck rentals has the same size truck for 58.95 plus $0.36/mile. At how many mile will the cost be the same?

Answers

Answer:

52 miles

Step-by-step explanation:

Step one:

given data

Buckeye truck rentals

daily rate of $59.99

plus $0.34/mile

let the number of miles be x

and the total charge be y

so

y= 0.34x+59.99---------------1

Goodyear truck rentals

daily rate of 58.95

plus $0.36/mile

let the number of miles be x

and the total charge be y

so

y= 0.36x+58.95---------------2

Step two:

Equate the two equations above to find x

0.34x+59.99=0.36x+58.95

collect like terms

59.99-58.95=0.36x-0.34x

1.04=0.02x

divide both sides by 0.02

x= 1.04/0.02

x=52 miles
