Larry paid 11.20 for four gallons of gas. How much was each gallon of gas

Answers

Answer 1

Answer: all u do is divide 11.20 by 4 which is 2.8 which is 2.8 so each gallon costs $2.8.

Answer 2

Answer: 11.20 : 4 = 2.8
Because when you want to calculate how much money you pay for the number of gallons of gas, you have to take a price of something multiply the number of gallons. Similarly, when you want to find the price of a gallon of gas, you have to take the total cost divided by number of gallons of gas you buy.

One day, ms sanders notices that her car’s odometer has exactly 1000 miles on it. She knows she drives 14 miles every day to and from PLA. Three days later, she looks at her car’s odometer again. How many miles are on the odometer ( considering she hasn’t driven anywhere else.)

Answers

The answer should be 1,084
Explanation: she drives 14 miles to PLA and 14 miles from PLA. that’s 28 miles in a day multiply the 3 days she travels back and forth and it gives you 84 miles, plus the 1000 she already had.

How to simplify a given expression?

The given expression can be simplified by eliminating the common terms from the denominator and numerator. By doing this, the expression can be simplified.

The given expression is:

$(x^(2)-1 )/(x^(2)-x)$

It can be simplified as shown below:

$(x^(2)-1 )/(x^(2)-x) = ((x+1)(x-1 ))/(x(x-1))$

The numerator is split using the identity :

$a^(2) -b^(2) =(a+b)(a-b)$

It can be further simplified as follows:

$(x^(2)-1 )/(x^(2)-x) = ((x+1)(x-1 ))/(x(x-1))\n= (x+1)/(x) \n=(x)/(x) +(1)/(x) \n= 1+(1)/(x)$

We have simplified the given expression into 1 + 1/x.

Thus, the expression x^2-1 / x^2-x in its simplest form is 1 + 1/x.

How do i divide negative numbers

Answers

Divide normally but if you are dividing 2 negative number the answer will be positive but if you have a negative and positive number the answer will be negative

well for example if you have just 1 or and odd (1,3,5 etc.) amount of negitive numbers in the equation then you divide it normaly and then put a negitive sign in front of your answer. But if you have an even number of negitives, like 2, then you divide normaly and DO NOT add the negitive sign to your answer. (you can remember it if you think odd negitives=negitive and even negitives= positive)

ex. -9÷3 there is an odd number of negitives so you know the answer will be negitive so put a negitive sign to not forget. = -? then you forget about the signs and solve the equation. =3 then put it together and you get = -3

same for even amount of negitive numbers but you dont place the negitive sign and completly forget about negitives. good luck

Reflection all symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane. A) rotated about an axis
B) translated along a line
C) rotated about a point

Answers

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

What is reflectional symmetry?

Consider a plane. Consider a design or shape on that plane. Now consider an axis.

If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.

Instead of that mirror intuition, we can also think that we sort of rotated that image about that considered axis, and after half rotation, the figure is again onto its plane. If that rotated figure looks alike to the initial figure, then that figure has rotational symmetry.

Thus, reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.
