Julio rented a bike from Krystal's Bikes. It
cost $13 plus $2 per hour. If Julio paid $17,
then he rented the bike for how many hours?

Answers

Hello!

The first thing we need to determine is: what exactly are we trying to find? Well, in this case, that would be the amount of hours Julio rented a bike for. We can set that number as a variable: x

We know that the rental total was 17 dollars. Therefore, we will set our equation equal to 17: (equation)=17

Next, we know that the rental costed 13 dollars upfront plus 2 dollars for every hour he rented it for. We can substitute “x” in for the amount of hours he rented it for, since that is what we are trying to find. We will multiply that by 2, since he has to pay 2 dollars for ever “x” hour he rents the bike. Add 13 dollars to that, since he has to pay that upfront: 2x+13=17

Now, let’s solve for x! Start by subtracting 13 from each to get the “2x” by itself:

2x=4

Now divide each side by 2 to get the value of x

X=2

Therefore, Julio rented the bike for 2 hours!

I hope this helped! Comment if you have any questions!

The number of hours should be 2.

Given that,

There is the cost of $13 plus there is $2 per hour.And, the amount paid is $17.Here we assume the number of hours be x.

Based on the above information, the equation is as follows:

2x + 13 = 17

2x = 17 - 13

2x = 4

x = 2

Therefore we can conclude that the number of hours should be 2.

Answers

Answer:

No.

Step-by-step explanation:

Take the second expression: 5(2 - 20)

To solve, you must distribute the 5 to all terms within the parenthesis:

5(2 - 20) = (5 * 2) - (5 * 20) = 10 - 100 = -90

On the other hand:

10 - 20 = -10

∴ the two expressions are not equivalent.

Step-by-step explanation:

Given

[tex]\sqrt{2x-3}[/tex] + 4 = 7 ( subtract 4 from both sides )

[tex]\sqrt{2x-3}[/tex] = 3 ( square both sides )

2x - 3 = 3² = 9 ( add 3 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

WILL.MARK BRAINLEST. ( The length of a rectangular garden is 5m longer than its breadth .If its perimeter is 150 m,find the area of the garden ) step by step​

Answers

Answer:

1400m^2

Step-by-step explanation:

Solution,

Let the breadth of the rectangle be x m, then the length of the rectangle will be x+5 m,

Now,

Perimeter of the rectangle=2(l+b)

150=2(x+5+x)

150=2(2x+5)

150=4x+10

150-10=4x

140=4x

140/4=x

35=x

So, the breadth of the rectangle=35 m

and length=(35+5)m=40m

Again,

Area of the rectangle=l×b

=40m×35m

=1400 m^2

I hope it helped U

stay safe stay happy

Answer: Area= 1400[tex]meter^{2}[/tex]

Step-by-step explanation:

ok  so  we can assume the

breadth=X

so, length = X+5 (because the length is 5 meters more than the breadth)

perimeter= 150 meters

the formula of the perimeter of a rectangle = 2 x ( Length + Breadth)

so now if we put the values,

2 * ( X+5 +X) = 150 ( because 150 is the perimeter)

2 * (2X + 5) = 150 (the value became 2x because when we add two variables with the same value it will be written as 2(any variable)).

now we multiply  2 with both sides

so ( 2 * 2X) + (2 * 5)

hence, 4X + 10 = 150

now we will solve the equation,

4X= 150 -10 (because we did transposal the signs will change from "+" to "-")

4x= 140

again with the transposal (when we write a number with a variable it shows that it means the number multiplied by the variable in this case it is 4 multiplied by X ) so when we transpose we will have to divide because multiplication turns into division while transposing

so now,

X= 140÷4

which is equal to 35

so finally X = 35

so as we have written in the beginning breadth= X

and LENGTH= X+5

so now we have found X

BREADTH= 35

LENGTH= 40 (because 35+5 is 40)

now we have to find area the formula for finding the area is LENGTH×BREADTH

so, 40 × 35 = 1400

now we put the unit which is square meters also known as [tex]m^{2}[/tex]

so there is your final answer 1400[tex]m^{2}[/tex]

Is the inequality sometimes, always, or never true?

Answers

Answer:

never true.

Step-by-step explanation:

Answer:  Never true

Work Shown:

-2(2x+9) > -4x+9

-4x-18 > -4x+9 ... distribute

-18 > 9 .... add 4x to both sides; they cancel

The last inequality is false regardless of which x value you pick. Since the last inequality is always false, that means the first inequality is always false.

f(x)= -2x^2 - 5 and f(2)= -13

can someone solve this in steps please?

Answers

This is one way you could write out the steps

f(x) = -2x^2 - 5

f(2) = -2(2)^2 - 5

f(2) = -2(4) - 5

f(2) = -8 - 5

f(2) = -13

Answer:

Step-by-step explanation:

First you have to get the meaning clear.

f(2) means that wherever you see an x on the right side of the equation, you put a 2.

f(2) means -2*(-2)^2 - 5

(-2)^2 = -2 * -2 = 4

f(2) = -2 * 4 - 5

f(2) = - 8 - 5

f(2) = -13
