General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define Equation
-a = -24
Step 2: Solve for a
Divide both sides by -1: a = 24Step 3: Check
Plug in a into the original equation to verify it's a solution.
Substitute in a: -(24) = -24Multiply: -24 = -24Here we see that -24 does indeed equal -24.
∴ a = 24 is the solution to the equation.

Tank A contains 35 gallons of water and is increasing at a rate of 5 gallons per minute. TankB
contains 100 gallons of water and is decreasing at a rate of 8 gallons per minute. In how
many minutes will the tanks contain the same amount of water? How much water will
that be?
9514 1404 393
Answer:
5 minutes; 60 gallons
Step-by-step explanation:
The volume in tank A is initially 35 gallons. Its rate of change is 5 gallons per minute. The equation for volume can be written as ...
y = 35 +5x . . . . . . where y is gallons, and x is minutes
The volume in tank B is initially 100 gallons. Its rate of change is -8 gallons per minute. The equation for volume can be written as ...
y = 100 -8x
We want to find the values of x and y such that both are the same for both tanks.
35 +5x = y = 100 -8x
13x = 65 . . . . . . . . add 8x-65 to both sides of the equation
x = 5
y = 100 -8·5 = 60
Both tanks will hold 60 gallons after 5 minutes.

Step-by-step explanation:
today, the city of madison has a population of 6.34 million residents. in 1914, the population was just 1.9 million residents. how much has the population increased since 1914?
The population has increased by 4.44 million
How calculate the population increase ?The current population of the city is 6.34 million residents
In 1914 of the city was 1.9 million residents
Therefore the population increase can be calculated by subtracting the population of residents in 1914 from the population after the year 1914, this means subtracting 1.9 million from 6.34 million
= 6.34 - 1.9
= 4.44
Hence the population increase is 4.44 million

Each of the two congruent sides of an isosceles triangle is 8 inches less than twice the base. The perimeter is 74 inches. What is the length of the base?
Answer:
[tex]18\; {\rm in}[/tex].
Step-by-step explanation:
Let [tex](x\; {\rm in})[/tex] be the length of the base.
The question states that the length of each congruent side is [tex]8\; {\rm in}[/tex] less than twice the length of the base. Twice the length of the base would [tex](2\, x\; {\rm in})[/tex]. The length of each congruent side would be [tex](2\, x - 8)\; {\rm in}[/tex].
Sum up the length of each side to find the perimeter of this triangle:
[tex](2\, x - 8) + (2\, x - 8) + x = 5\, x - 16[/tex].
Substitute in the actual perimeter of this triangle:
[tex]5\, x - 16 = 74[/tex].
Solve for [tex]x[/tex]:
[tex]x = 18[/tex].
Therefore, the length of the base of this isosceles triangle would be [tex]18\; {\rm in}[/tex].

Drag the correct steps into order to solve the equation -6x+18=-6 for x.
Answer:
When solving for x in the following equation: -6x + 18 = -6
step 1: -6x +18 - 18 = -6 - 18 (subtract 18 from both side)
step 2. -6x/-6 = -24 / -6 (divide both sides by -6 to isolate x by itself)
x = 4
Step-by-step explanation:
The value of x in the expression - 6x + 18 = - 6, is 4.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given an expression - 6x + 18 = - 6 solving for x is the same as finding the value of x.
∴ - 6x + 18 = - 6.
- 6x = - 6 - 18.
- 6x = - 24.
6x = 24.
x = 4.

1 whole and 1/4 - 8/10 show your work please
Answer:
9/20
Step-by-step explanation:
first you have to make 1 1/4 an improper fraction so since the denominator is 4 you add 4 to the numerator which is 1 so your fraction would be 5/4.
Second you make the denominators the same so you have to multiply them together. but since your multiplying the denominators you have to multiply the numerator as well. so for 5/4 you would multiply both the numerator and denominator by 10 so your fraction will now be 50/40. now you multiply 8/10 by 4 so your new fraction is now 32/40
Third you subtract. you only have to subtract the numerators so 50-32 is 18 so your answer is 18/40
Last you need to simplify the highest number you can divide both of them by is 2 so now you divide 18 by 2 which makes 9 then you divide 40 by 2 which is 20 so your answer is 9/20

Kendra wants to know how many flower arrangements can Kendra make that have the same number of daisies and roses in the arrangement
Roses will have six arrangements, while daisies will have ten.
Each bouquet will contain two flowers.
What does HCF in mathematics?The highest common factor (HCF) between two or more numbers is two.
Amanda is arranging flowers in accordance with the question. She has 36 tulips, 20 daises, and 16 roses.
Every bouquet must have an equal amount of daisies, a reasonable quantity of roses, and an equal number of tulips.
The least common divisor, which is 2 instead of HCF, which would make it the least amount of arrangements, is the most arrangements she is capable of making.
based on the facts provided;
So,
20 daisies divided by 2 is 10 arrangements.
12 roses divided by 2 is 6 arrangements.
There will be 2 flowers in each kind of arrangements.

a circular oil spill continues to increase in size. the radius of the oil spill, in miles, is given by the function r(t)
A composite function to find the area of the region at time t is written as-
A(r(t)) = π(0.25 + 2t + 4t²)
What is composite function?f(g(x)) or (f ∘ g)(x) represents the composition of functions f(x) & g(x), where g(x) acts first (x). It integrates a number of functions to produce another.
The output of one function inside the parenthesis is becoming the input of the other function in a function composition. i.e.,
In f(g(x)), g(x) is f's input (x).In g(f(x)), f(x) is g's input (x).Now, as per the given question;
To create a composite function, we pertain one function to another. In this scenario, we would like to find area in terms of time, so we apply the function A(r) to the function r. (t).
To accomplish this, we substitute r with r(t).
Since we know that r(t) = 0.5 + 2t, we can replace r to 0.5 + 2t:
A(r(t)) = π(0.5+2t)²
To make things easier, we'll simplify this same squared term:
A(r(t)) = π(0.5 + 2t)(0.5 + 2t)
A(r(t)) = π[(0.5×0.5) + (0.5×2t) + (2t×0.5) + (2t×2t)]
A(r(t)) = π(0.25 + t + t + 4t²)
A(r(t)) = π(0.25 + 2t + 4t²)
Therefore, the composite function to find the area of the region at time t is written as A(r(t)) = π(0.25 + 2t + 4t²).
