The amount of gallons of gas that can be bought with $12 is 2.64 gallons.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Cost of gas per gallon = $4.55
This can be written as,
1 gallon = 4.55
Multiply 12/4.55 on both sides.
12/4.55 gallons = 12/4.55 x 4.55
2.64 gallons = 12
This means,
2.64 gallons for $12.
Thus,
2.64 gallons can be bought for $12.

42.Anna pours herself some room-temperature soda from a bottle and adds four ice cubes. In a few minutes the ice cubes are smaller and the soda is much colder. Which of the following best explains the change in temperature of the soda?
A. Heat flowed from the soda to the ice cube and caused it to partially melt.
B. Coldness flowed from the ice cube to the soda, making the soda cooler.
C. The cold water from the melting ice went into the soda, replacing the warmer water that was in the soda
D. The water from the melting ice makes the soda more dilute, and the lower concentration makes the temperature lower.
and send me link for explenation
Answer:
Option A
Step-by-step explanation:
According to the second law of thermodynamics, heat always flows from hot to cold places, unless work is done on the system. In this case the ice is colder than room temperature, and therefore the heat flows from the soda to the ice cube. The ice cube absorbs the heat, and partially melts.
Given that f(x) = x2 – 12x + 27 and g(x) = x – 9, find (f g)(x) and express

Two numbers have a difference of 13. The sum of twice one number and 3 times the other number is 1. Write a system of equations and solve the system to find the two numbers. You need not show 7 steps for this problem. Just show the system, solve the system, and write the two numbers.
Answer:
first number = 8
second number = -5
Step-by-step explanation:
Let
x = first number
y = second number
Two numbers have a difference of 13.
x - y = 13
The sum of twice one number and 3 times the other number is 1
2x + 3y = 1
x - y = 13 (1)
2x + 3y = 1. (2)
From (1)
x = 13 + y
Substitute into (2)
2x + 3y = 1.
2(13 + y) + 3y = 1
26 + 2y + 3y = 1
26 + 5y = 1
5y = 1 - 26
5y = -25
y = -25/5
y = -5
Substitute y = -5 into (1)
x - y = 13
x - (-5) = 13
x + 5 = 13
x = 13 - 5
x = 8
The obtained number is 12. And the system of equations is 2c + 4p = 40
How to solve system of equations ?Although each chicken has two legs and each pig has four legs, the total number of animal legs is:
2c + 4p = 40
Once we simplify the above equation, we get
c + 2p = 20
We also know that there are 16 animal heads in total, which can be expressed as:
c + p = 16
We can solve for "c" that use these two equations.
Once we multiply the second equation by 2, we get:
2c + 2p = 32
Once we subtract this equation from that, we get:
2p = 8
Once we solve for "p," we get:
p = 4
Substituting this "p" value into the second equation yields:
c + 4 = 16
Once we solve for "c," we get:
c = 12
As an outcome, your parents hold 12 chickens.

Factorise
x^2+18x+80
Answer:
(x + 10)(x + 8)
Step-by-step explanation:
Given
x² + 18x + 80
Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)
The factors are + 10 and + 8 , since
10 × 8 = + 80 and 10 + 8 = + 18 , then
x² + 18x + 80 = (x + 10)(x + 8) ← in factored form

6x + 15y = -15
Answer:
-2/5-1
Step-by-step explanation:
6x+15y=(-15)
subtract both sides by (-6x)
now the equations becomes: 15y=(-6x)-15
divide both sides by 15, since -6 cannot evenly we just leave it as a fraction
Equation becomes y= -6/15x-1
Then simplify it down to y= -2/5x-1
