Answer:

If im correct its $281.08

Step-by-step explanation:

Then i added the first number to the total

$82.50+$198.58 ( those are all the numbers i added at the beginning.)

Then it should equal $281.08

He had $281.08 before he paid his bills.

Answer:

7/6

Step-by-step explanation:

7/8 * 4/3

7/2 * 1/3

7/6

Answer:

When you divide a fraction, make the second number the reciprocal. Then multiply them.

So it is

3/4 = 4/3

7/8 * 4/3 = 28/24

28/24 is the answer

Simplified = 7/6 or 1 1/6

the room charge for a hotel is 230$ each day. the estevez family spends 4 days on vacation at the hotel . at the end of their stay they leave a 10% tip of the total room bill for the person who cleans their room. how much is the total bill including the tip for the person who cleans the room? explain

Answers

It's 230 per day and they spend 4 days so multiply 230 × 4 = 920

920 is the room charge. Now multiply 920 × 10% for the tip.

920× .10 = 92 that's the top

Add the tip to the room charge

920 + 92 = $1,012

10% of 230 is 23 so
230
+23 =
253

Find the solution set of this inequality|10x+20| ≤10

Answers

Answer:

solution is

[-3,-1]

Step-by-step explanation:

we are given

$|10x+20|\leq 10$

Firstly, we will find critical values

so, let's assume it is equal

$|10x+20|= 10$

now, we can break absolute sign

For $|10x+20|= -(10x+20)$ :

$-(10x+20)= 10$

we can solve for x

$-10x-20= 10$

Add both sides by 20

$-10x-20+20= 10+20$

$-10x= 30$

Divide both sides by -10

and we get

$x=-3$

For $|10x+20|= (10x+20)$ :

$(10x+20)= 10$

we can solve for x

$10x+20= 10$

Subtract both sides by 20

$10x+20-20= 10-20$

$10x= -10$

Divide both sides by 10

and we get

$x=-1$

so, critical values are

$x=-3$

$x=-1$

now, we can draw a number line and locate these values

and then we can check inequality on each intervals

For $(-\infty,-3)$ :

We can select any random value from this interval and plug that in inequality

and we get

we can plug x=-5

$|10* -5+20|\leq 10$

$|-50+20|\leq 10$

$30\leq 10$

so, this is FALSE

For $[-3,-1]$ :

We can select any random value from this interval and plug that in inequality

and we get

we can plug x=-2

$|10* -2+20|\leq 10$

$|-20+20|\leq 10$

$0\leq 10$

so, this is TRUE

For $(-1,\infty)$ :

We can select any random value from this interval and plug that in inequality

and we get

we can plug x=0

$|10* 0+20|\leq 10$

$|0+20|\leq 10$

$20\leq 10$

so, this is FALSE

so, solution is

[-3,-1]
