Aydin walks his dog Dexter regularly. Aydin walks Dexter 5 miles every 8 days. Over the last 40 days how far have Aydin and Dext
EastWind [94]
I do this differently from many people, but the answer is 25 miles. If they walk 5 miles every day, and it’s a 40 day process, you multiply 8 by 5, which equals 40. After that you multiply 5 by 5 and you get 25. Sorry if that’s hard to understand, but the answer is 25.

use the quadratic formula to find both solutions to the quadratic equation given below. check all that apply 5x^2-x-4=0
Setler79 [48]

Answer:

x = -4/5 and x = 1

Step-by-step explanation:

5x^2 - x - 4 = 0

Factor out x from the expression.

x (5x +4) - 5x -4 = 0

Factor out the negative sign from the expression.

x (5x + 4) - (5x+4) = 0

Factor out 5x + 4 from the expression.

(5x +4) x (x-1) = 0

When the product of factors equal 0, that means atleast one factor is 0.

5x+4= 0

x-1 = 0

Solve the equation for x.

5x + 4 = 0

Minus 4 from both sides.

5x = -4

Divide by 5.

x = -4/5

Solve the equation for x.

x - 1 = 0

Add one to both sides.

x = 1

Therefore, x = -4/5 and x = 1.

damaskus [11]

The question is incomplete. Here is the complete question:

Val rented a bicycle while she was on vacation. She paid a flat rental fee of f dollars, plus $8.50 each day. The total cost at the end of her vacation was t dollars. Let d represent the number of days Val rented the bicycle. Write an equation representing the total cost at the end of her vacation.

Answer:

t=f+8.5d

Step-by-step explanation:

Given:

Flat rental fee = f

Variable fee per day = $8.50

Total cost at the end vacation = t

Number of days of her vacation = d

Using unitary method, we can find the variable fee for 'd' days.

1 day variable fee = $8.50

Therefore, 'd' days variable fee = 8.50d

Total cost at the end of her vacation can be obtained by adding the fixed rental fee and the variable fee obtained for the given number of days.

Now, total cost is given as:

Total cost = Flat rental fee + Variable fee

Substituting all the variables and framing above in the form of an equation, we get:

t=f+8.5d

Therefore, the equation representing the total cost at the end of her vacation is t=f+8.5d
