Including a 7% sales tax, an inn charges $125.19 per night. Find the inn's nightly cost before tax is added.
The inn's nightly cost before tax is added is $23.54
Taxes are prices added on top of goods and services
Let the normal price be x
Price including tax = x + 0.07x (note that the tax iss 7%)
Given that Price including tax = $125.19, then;
$125.19 = x + 0.07x
Find the value of x
125.19 = 1.07x
Swap
1.07x = 125.19
x = 125.19/1.07
x = $23.54
This shows that the inn's nightly cost before tax is added is $23.54

what is the answer for this Evaluate 3|-3|.
Answer: 9
Concept:
Here, we need to know the idea of absolute value.
The absolute value of a number or integer is the actual distance of the integer from zero, in a number line.
There are no negatives in absolute value. So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive.
Solve:
Given
3 |-3|
Expand absolute value sign, which means making [-3] positive

Determine the value of x.
A) 78°
B) 160°
OC) 80°
D) 240°
Answer:
c
Step-by-step explanation:
Help Me please ,I need help ,someone help me!
Step-by-step explanation:
Since the integers are consecutive,
let the smaller one be x
then the larger will be x+1
Now their sum is -15
x+x+1=-15
2x=-15-1
2x=-16
x=-8
Therefore the smaller is -8 and the larger is -7
Now when one is added to the smaller integer it becomes -8+1=-7
If 2 is subtracted from the larger one it becomes -7-2=-9
their product therefore becomes -9×-7=63

f(x) = 3x2 – x
Find f(10)
Answer: f(10) = 290
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given expression
f(x) = 3x² - x
Substitute values into the expression
f(10) = 3(10)² - (10)
Simplify exponents
f(10) = 3(100) - (10)
Simplify by multiplication
f(10) = 300 - 10

Trista has 8 mg of iron and 0.83 mg of tin.
How much more iron does she have than tin?
8.83 mg
7.17 mg
7.27 mg
71.7 mg
Here, we need to subtract the quantity of tin from the quantity of iron in order to find how much more iron Trista has than tin
The quantity of iron Trista has more than tin is 7.17 mg
Quantity of iron = 8 mg
Quantity of tin = 0.83 mg
Quantity of iron Trista has more than tin = Quantity of iron - Quantity of tin
= 8 mg - 0.83 mg

13. In ADGE,DG = 8,GE = 17, and DE = 15. What is the length of DF? Round to the nearest hundredth.
Answer:
Step-by-step explanation:
The trick is not to get all caught up in Pythagoras. There is a much simpler way to do it. Find the area of the triangle two different ways. DG and DE are at right angles. That is one way to find area. The other is use the height (DF) and multiply that by the hypotenuse GE.
DG*DE/2 = GE * DF/2 Multiply both sides by 2
DG*DE = GE * DF
DG = 8
DE = 15
GE = 17
8*15 = 17* DF
120 = 17 * DF Divide by 17
120/17 = DF
DF = 7.06
