[tex]17x+22.22-13.45x\geq 43.67\\\\(17x-13.45x)+22.22\geq 43.67\\\\3.55x+22.22\geq 43.67\\\\3.55x\geq 43.67-22.22\\\\3.55x\geq 21.45\\\\x\geq \frac{21.45}{3.55} \\\\x\geq 6.04...[/tex]
but we don't wake a 0.4 of a week so we need the next whole number 7
so it will take 7

Charlotte drove 304 miles in 8 hours. If she continued at the same rate, how long would it take to travel 190 miles?
The time to travel 190 miles will be 5 hour.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Charlotte drove 304 miles in 8 hours.
And, She continued at the same rate.
Now,
Since, Charlotte drove 304 miles in 8 hours.
Hence, The speed is,
Speed = Distance / time
= 304 / 8
= 38 miles / h
So, For travel 190 miles at same rate;
Time = Distance / Speed
= 190 / 38
= 5 hour
Thus, The time to travel 190 miles will be 5 hour.

Certain cooking oil has a density of 0.91 grams per milliliter. Which of the following series of calculations correctly determines the mass, in kilograms, of 15 liters of this oil?
Answer:
Step-by-step explanation:
Here is a picture of the answer, since I couldn't put into words!
The mass of 15 liters of oil is 13.65 kg.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
What is the density?Density is the ratio of the mass of the body to the volume of the body.
Density = Mass / Volume
Given that oil has a density of 0.91 grams per milliliter
To determines the mass, in kilograms, of 15 liters of this oil
Rearranging the equation,
Mass = Density × Volume
∵ 15 liters = 15000 milliliters (ml)
So, 0.91g/ml x 15000ml = 13650g
∵ 1 kilogram = 1000grams
⇒ 13650g / 1000g/kg
⇒ 13.65kg
Thus, the mass of 15 liters of oil is 13.65kg.

The length of a rctangle is to more than the
width. The perimeter of the rectangle is 72 meters
What is the length of the rectangle?
Answer:
19 m
Step-by-step explanation:
The width is 2 less than the length, so the perimeter is ...
P = 2(L +W)
72 = 2(L +(L -2))
76 = 4L . . . . . . . . add 4
19 = L
The length of the rectangle is 19 meters.

The solution for the expression is x = -4.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To solve for x in the equation
(9/8)^(3x+12) = 1
we can take the natural logarithm of both sides and use the properties of logarithms to simplify.
ln[(9/8)^(3x+12)] = ln(1)
(3x+12) ln(9/8) = 0 (since ln(1) = 0)
3x + 12 = 0 (since ln(9/8) ≠ 0)
3x = -12
x = -4
Therefore,
The solution is x = -4.

Find the midpoint of the line segment joining the points (-1, -2) and (-3, 13).
The midpoint is
(Simplify your answer. Type an ordered pair)
A mid-point divides a line segment into 2 equal parts . Hence the line is divided in 1 : 1 ratio.
Let
x(1) = -1
y(1) = -2
x(2) = -3
y(2) = 13
So according to Section formula , cordinate of the mid - point (x' , y') =
[tex](x' , y') = ( \frac{ {x}^{1} + {x}^{2} }{2} , \frac{{y}^{1} + {y}^{2} }{2} )[/tex]
So using the formula & putting the values above
[tex]( \frac{ - 1 - 3}{2} , \frac{ - 2 + 13}{2} )[/tex]
[tex] = > ( \frac{ - 4}{2} , \frac{11}{2} )[/tex]

How to identify the parent function given an equation ?
Answer:
You can identify the parent function by making the equation into its simplest form.
Step-by-step explanation:
Remove all transformations from the equation (such as plus/minus signs, constants, and extra terms in the equation).
ex. y= -3x^2+15
The parent function would be y=x^2 after removing everything.

Answer:
x^2 + -9 x + 18 = (x - 9) x + 18 = (x - 6) (x - 3) all three are alternanate forms.
Step-by-step explanation:
Expand the following:
(x - 6) (x - 3)
Hint: | Multiply x - 6 and x - 3 together using FOIL.
(x - 6) (x - 3) = (x) (x) + (x) (-3) + (-6) (x) + (-6) (-3):
x x - 3 x - 6 x - 6 (-3)
Hint: | Combine products of like terms.
x x = x^2:
x^2 - 3 x - 6 x - 6 (-3)
Hint: | Multiply -6 and -3 together.
-6 (-3) = 18:
x^2 - 3 x - 6 x + 18
Hint: | Group like terms in x^2 - 3 x - 6 x + 18.
Grouping like terms, x^2 - 3 x - 6 x + 18 = x^2 + (-3 x - 6 x) + 18:
x^2 + (-3 x - 6 x) + 18
Hint: | Combine like terms in -3 x - 6 x.
