In step 3 each side of the equation is divided by - 0.3 to obtain the value of a = 8.3.
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Consider the expression,
0.8a - 0.1a = a - 2.5
Step 1,
Subtracting similar terms,
a( 0.8 - 0.1 ) = a - 2.5
0.7a = a - 2.5
Step 2: Subtracting the term a from each side of the equation.
0.7a - a = a - 2.5 - a
- 0.3a = - 2.5
Step 3: Multiplying each side of the equation by - 1.
- 0.3a × - 1 = - 2.5 × - 1
0.3a = 2.5
Dividing each side of the equation by 0.3.
a = 2.5/0.3
a = 8.3

The recipe for a homemade glass cleaner indicates to use a ratio of 1 part vinegar to 4 parts water. Autumn used 2.25 ounces of vinegar and 9 ounces of water. Is the relationship between vinegar and water in the recipe and vinegar and water in Autumn's cleaning solution a proportional relationship?
Combine 1 part distilled vinegar and 10 parts warm water in a spray bottle. Wipe the window down with a gentle, clean, lint-free microfiber cloth or paper towel to remove any dust before applying your solution. Spray the entire surface after that.
How does a proportionate relationship work?Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.If a table displays a proportional relationship, the ratio of each pair of values can be determined. The table depicts a proportionate relationship if all of those ratios are the same.The equation y = kx represents a proportionate relationship between two quantities y and x that have the same proportionality constant, k.A linear relationship between two amounts or variables is referred to as proportionality in mathematics. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.To know more about proportional relationship refer to:

The probability that at least 1 American will say that they have been decapitated is (C) 0.15.
What do we mean by probability?Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates that the event is impossible and 1 indicates certainty.The likelihood that something will happen can be summed up as probability.We can talk about the likelihood or likelihood of different outcomes when we don't know how an event will turn out.Events that follow a probability distribution are the subject of statistics.So, the probability that at least 1 person will say yes:
We know that 15% will say yes, then:
20/100 × 15 = 3Probability formula: P(E) = favorable events/ Total events
Now, put values and solve as follows:
P(E) = favorable events/ Total eventsP(E) = 3/20P(E) = 0.15Therefore, the probability that at least 1 American will say that they have been decapitated is (C) 0.15.

The expression rewrites the total 32 + 80 using the largest common factor and the distributive property, and the expression can be expressed as 16(2 + 5).
Option (c) is correct.
The least common multiple of two integers is defined as the lowest number that is a multiple of two or more numbers. The abbreviation LCM stands for least common multiple.
It is assumed that:
The mathematical formula is:
= 32 + 80
To identify the most prevalent factor:
GCF( 32, 80) ( 32, 80) ( 32, 80)
We can use Euclid's division lemma to find the GCF:
GCF(32,80)= 16
The phrase 32 + 80 can be expressed as follows:
= 32 + 80\s= 16(2 + 5)
As a result, the equation rewrites the total 32 + 80 using the largest common component and the distributive condition, and the expression can be expressed as 16(2 + 5).

An amusement park charges $32 for admission and $6 to park your car.
To ascertain the maximum or lowest values of a scenario with many restrictions, a system of linear inequalities is frequently utilized. Inequalities reflect a limit of what is permitted or achievable rather than a precise quantity.
Suppose that everyone is going in one car and x is the number of persons in the car. The inequality represents the possible number of people that could go for $166 is,
32x+6≤166
32x≤160
x≤160/32

Let P be a polynomial function, and P(x)=x4−dx3+8x2−14x+16. If (x−2) is a factor of the polynomial, what is the value of d? Explain or show how you know.
The value of d is x - 2 is a factor of the polynomial function P(x) is 4.5
How to calculate the value of d?The polynomial function is given as
P(x) = x⁴ − dx³ + 8x² −14x + 16
Also, we have the factor of the polynomial to be
x - 2
Set the factor to 0
So, we have
x - 2 = 0
Solve for x
x = 2
If truly, the variable x - 2 is a factor of the polynomial, then the following must be true
P(2) = 0
Start by substituting 2 for x in the equation P(x) = x⁴ − dx³ + 8x² −14x + 16
So, we have
P(2) = (2)⁴ − d(2)³ + 8(2)² −14(2) + 16
Evaluate the exponents
P(2) = (16) − d(8) + 8(4) −14(2) + 16
Evaluate the sum of products
P(2) = −8d + 36
Set to 0
−8d + 36 = 0
So, we have
−8d = - 36
Divide
d = 4.5
Hence, the value of d is 4.5

A.f(x)=(0.5)^x
B.f(x)=5*x
C.f(x)=(1/15)^x
D.f(x)=(1/5)^x
The answer will be f(x) = 5*. If f′(x)>0 on an open interval, then f is increasing on the interval and If f′(x)<0 on an open interval, then f is decreasing on the interval.
Which function is making f X larger?For a given function, y = F(x), the function is known as an increasing function if the value of y increases as the value of x increases, and the function is known as a decreasing function if the value of y decreases as the value of x increases.The order of the numbers is said to be growing if they are written from smallest to largest, but decreasing order is used when the numbers are written from largest to smallest.You must first compute the derivative, then make it equal to 0, and then determine which zero values the function is negative between in order to determine whether a function is decreasing. In order to determine when the function is negative and, consequently, decreasing, test values on all sides of these.Hence, The answer will be f(x) = 5*. If f′(x)>0 on an open interval, then f is increasing on the interval and If f′(x)<0 on an open interval, then f is decreasing on the interval.

80% of a number is equal to two-thirds of a second number.
The whole number ratio of the first number to the second number in its lowest terms is x:y
What is the value of x−y
?
Answer:
-1
Step-by-step explanation:
Let's assume 100 as the number. 80% of that number is 80. That's A. And since 80 is two-thirds of that number, the second number has to be 120. Simplifying that would give 5/6. 5-6 = -1
Answer: 1:1.2
1-1.2= -0.2
Step-by-step explanation:
x = first number
y = second number
80/100*x (80 percent of one number)
2/3*y (two thirds of the second number)
equating
80/100*x=2/3*y
= 1.2=y
substituting:
80/100*x = 2/3 * 1.2
= x=1
substituting the value of x in the original equation
80/100 * 1 = 2/3 * y
= y=1.2
so, x=1, y=1.2
x:y
=1:1.2
x-y= 1 - 1.2 = -0.2

What is linear equation ?
An equation between two variables that gives a straight line when plotted on a graph or say first degree equation is also known as linear equation.
The equation of first steps is
=> 2(5x+4) = 7(2)
=> 5x + 4 = 14
Now, subtract 4 from 14
