The total number of hours was 7 so divide $28.84 by 7 and you'll get $4.12 per hour.

Answer:

The rental cost per hour is $4.12.

Step-by-step explanation:

A painter rented a wallpaper steamer at 9 am and returned it at 4 pm.

4 pm = 16:00 pm

He rented a wallpaper steamer for the time = 16:00 - 09:00 = 7:00 hrs.

He paid for 7 hours = $28.84

Therefore, for 1 hour = 28.84 ÷ 4 = $4.12

The rental cost per hour is $4.12.

The area of a rectangular wall of a barn is 96 square feet. Its length is 10 feet longer than the width. Find the length and wid

Bad White [126]

(x)(10+x)=96
$10x + {x}^{2} = 96$
${x}^{2} + 10x - 96 = 0$
(x-6)(x+16)=0

x=6,-16

negative can't be an answer this the answer is 6+10= 16 ft

Find three consecutive even interfere such that their sum is 50 more than the largest interfere

Vaselesa [24]

Hm. This is an interesting problem.

Let's see if we can express each of these numbers in terms of x and make an algebra equation to help us solve.

Consecutive even numbers increase by 2.

Let's allow x to equal our first number.

Let's allow x + 2 to equal our 2nd number.

Let's allow x + 4 to equal our 3rd number.

When we add those together, their sum need to equal 50 more than the largest integer (our x + 4)

Let's set it up!

x + (x +2) + (x + 4) = (x + 4) + 50

Simplify!

3x + 6 = x + 54

Let's reorganize the left and right sides.

3x - x = 54 - 6

2x = 48

x = 24 (our 1st even number)

Now, let's check our answer!

24 + 26 + 28 = 78

78 - 50 = 28 Our highest integer.

The sum of consecutive integers 24, 26, 28 is 50 more than the highest integer.

9+3|5-x|=24<br><br> What is the lines for and how do I solve X with them?

Ivahew [28]

Answer:

the lines represent absolute value bars

$x=0,10$

Step-by-step explanation:

STEP 1: Move all terms not containing |5−x| to the right side of the equation.

$3|5-x|=15$

STEP 2: Divide each term by 3 and simplify.

$|5-x|=5$

STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.

STEP 4: Set up the positive portion of the ± solution.

$5-x=5$

STEP 5: Solve the first equation for x.

$x=0$

STEP 6: Set up the negative portion of the ± solution.

$5-x=-5$

STEP 7: Solve the second equation for x.

$x=10$

NOTE: The solution to the equation includes both the positive and negative portions of the solution.

$x=0,10$

Can someone help? I don't understand.

Hence missing value in the solution to the equation is:(-5,2)

Step-by-step explanation:

We are given the equation:

$x-5y= -15$

and we need to complete the missing value in the solution to the equation

(-5,?)

Since the solution is in the form of ordered pair, so first value represent value of x and second value represents value of y i.e (x,y)

So, x= -5, Now finding y:

Putting value of x in given equation:

$x-5y= -15\\-5-5y= -15\\-5y=-15+5\\-5y=-10\\y=-10/-5\\y=2$

So, value of y is 2

Hence missing value in the solution to the equation is:(-5,2)
