17 - {19 - 2 x 4} = 17 - {19 - 8}
Step 3:
17 - {19 - 8} = 17 - 11
Step 4:

Including 8% sales tax, an inn charges $162 per night. Find
the inn's nightly cost before the tax is added.
Answer:
$150
Step-by-step explanation:
x + 0.08x = 162
1.08 x = 162
x = 150
The inn's nightly cost before the tax is added is $150.
Let's denote the inn's nightly cost before tax as "x." We are given that the inn charges $162 per night, including an 8% sales tax. This can be represented as an equation:
Total cost = Nightly cost before tax + Sales tax
$162 = x + 0.08x
Now, we can solve for "x":
$162 = 1.08x
x = $162 / 1.08
x = $150
So, the inn's nightly cost before the tax is added is $150.
We're asked to find the inn's nightly cost before the tax is added. Let's denote this cost as "x."
We are given that the total cost, including the 8% sales tax, is $162 per night. We can set up an equation using this information:
Total cost = Nightly cost before tax + Sales tax
Mathematically, this can be expressed as:
$162 = x + 0.08x
The 0.08x represents the 8% sales tax, which is 8% of the nightly cost before tax.
Now, we can combine the x terms on the right side of the equation:
$162 = 1.08x
To solve for x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 1.08:
x = $162 / 1.08
x = $150
So, the inn's nightly cost before the tax is added is $150. This means that if there were no sales tax, the inn would charge $150 per night. The 8% sales tax is then added to this base cost to reach the total of $162.

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
Step-by-step explanation:
breadth=x
length is 5m long then breadth
length=x+5
Perimeter=2(length+breadth)
subtitute values in formula:
150=2(x+5+x)
2x+5=150/2

f (8^9)p = 8^18, what is the value of p? (5 points)
A 2
B 9
C 10
D 18
Answer:
A
Step-by-step explanation:
I'm assuming p is an exponent.
You can multiply the exponent p with 9
8^9p = 8^18
Now we know that some number times the exponent 9 gives us 18.
Now, we isolate for p, by putting 9 on the other side, we know we can do this because both number have the same base (8)
therefore, 9p=18
p=18/9
p=2

1. Two more than the product of 3 and a number is -10. Determine the number.
2. The sum of three times a number and 20 is 11. Determine the number.
3. Seven-tenths of a number is 5.6 Determine the number.
Step-by-step explanation:
1. Let the number be a
2 + 3a = (-10)
3a = -10 - 2
3a = -12
a = -12/3 = -4.
2. Let the number be x

3a = 11 - 20
3a = -9
a = -9/3 = -3

A. 4, 6, 8
B. 4, 7, 10
C. 4, 8, 12

Option A "4, 6, 8".
This is because when we multiply 2x2, we get 4, then we add +2 with 4, we get 6, then we add again +2 with 6, we get 8. So, a list of three square numbers is completed.
Therefore, Option A is the correct answer.

The average of five numbers is 34. Two of the numbers are the same, and the other three are 49, 25, and 42. Find the value of the two numbers missing numbers.
Answer:
Both numbers = 27
Step-by-step explanation:
( x + x + 49 + 25 + 42)/ 5 = 34 Multiply both sides by 5
(2x + 49 + 25 + 42) = 34*5 = 170 Combine the left
(2x + 116) = 170 Remove the brackets.
2x + 116 = 170 Subtract 116 from both sides
2x = 170 - 116
2x = 54 Divide by 2
x = 54/2
x = 27
Check
27 + 27 + 49 + 25 + 42
170 / 5 = 34
It does check out.
27 is right.

Step-by-step explanation:
Unless you know that the top angle is a right angle (an assumption you should never make, but I will do it here because there is no other way to do it.)
Find the missing side of the triangle that is on the bottom triangle
b^2 = c^2 - a^2
b = ?
c = 11
a = 10
b^2 = 11^2 - 10^2
b^2 = 121 - 100
b = sqrt(21)
Now using the fact that
b / 10 = 10 / (x - b)
We know b from the previous problem
b = sqrt(21)
So now cross multiply
b ( x - sqrt(21) ) = 100
sqrt(21) * x - 21 = 100 Add 21 to both sides.
sqrt(21)x = 121 Divide by sqrt(21)
x = 121/sqrt(21)
x = 26.4
My first inclination is to tell your teacher it is unsolvable. Or you can ask him or her to show you how it is done. If they think the assumption I have made is correct, then you have the answer. Technically however, there is no answer.

What is at least 2 metaphors in this passage?
Until this day, how well the house had kept its peace. How carefully it had inquired, "Who goes there? What's the password?" and, getting no answer from lonely foxes and whining cats, it had shud up its windows and drawn shades in an old maidenly preoccupation with self-protection which bordered on a mechanical paranoia. It quivered at each sound, the house did. If a sparrow brushed a window, the shade snapped up. The bird, startled, flew off! No, not even a bird must touch the house! The house was an altar with ten thousand attendants, big, small, servicing, attending, in choirs. But the gods had gone away, and the ritual of the religion continued senselessly, uselessly.
Answer:
Step-by-step explanation:
it had shud up its windows and drawn shades in an old maidenly preoccupation with self-protection which bordered on a mechanical paranoia.
Put a like before an old maidenly aunt or woman. That makes it a simile. Take the like out and you have a metaphor.
Do the same thing with like in front of an alter. Take out the like and you have a metaphor.
What a grim and yet wonderful passage.
