what is 0.6(r 0.2)=1.8
the solution to the equation [tex]\(0.6(r - 0.2) = 1.8\) is \(r \approx 3.2\).[/tex]
To solve the equation 0.6(r - 0.2) = 1.8, we first distribute the 0.6 to the terms inside the parentheses:
0.6r - 0.6(0.2) = 1.8
0.6r - 0.12 = 1.8
Next, we add 0.12 to both sides of the equation to isolate 0.6r:
0.6r - 0.12 + 0.12 = 1.8 + 0.12
0.6r = 1.92
Now, to solve for r, we divide both sides of the equation by 0.6:
[tex]\[ \frac{0.6r}{0.6} = \frac{1.92}{0.6} \][/tex]
[tex]\[ r = \frac{1.92}{0.6} \][/tex]
[tex]\[ r \approx 3.2 \][/tex]
So, the solution to the equation [tex]\(0.6(r - 0.2) = 1.8\) is \(r \approx 3.2\).[/tex]
The probable question maybe:
solve the equation 0.6(r - 0.2) = 1.8

Write the following equation in general form 4x-6y=14
a. 4x-6y-14=0
b. 2x-3y=7
c. 2x-3y-7=0
Final answer:
The equation 4x - 6y = 14 can be written in general form as 4x - 6y - 14 = 0, which is option (a). This is the standard general form for a linear equation.
Explanation:
The equation given, 4x - 6y = 14, needs to be written in the general form. The general form of a linear equation is Ax + By + C = 0, where A, B, and C are constants. To rewrite the given equation in general form, we simply need to move all terms to one side of the equation. So the general form of the given equation is:
4x - 6y - 14 = 0.
This matches option (a) from the choices provided. It is important to note that a linear equation represents a straight line when graphed on the coordinate plane. The general form is helpful for various applications, including determining the x and y-intercepts.
Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month.

The ordered pair below is a solution to which equation? (2, 12) A.y=1/5x B.y=1/2x C. y = 2x D. y = 6x
Answer:
D. y = 6x
Step-by-step explanation:
In order to conclude which pair is a real solution to one of these equations, we need to evaluate the point in each equation.
Let:
[tex](x,y)=(2,12)[/tex]
So, this pair will be a solution if when evaluating the value of x=2 in the function the result is y=12.
For A.
[tex]y(x)=\frac{1}{5}x \\\\y(2)=\frac{2}{5} =0.4\neq12[/tex]
This pair is not a solution to this equation.
For B.
[tex]y(x)=\frac{1}{2}x\\\\y(2)=\frac{2}{2} =1 \neq 12[/tex]
This pair is not a solution to this equation.
For C.
[tex]y(x)=2x\\\\y(2)=2*2=4 \neq 12[/tex]
This pair is not a solution to this equation.
For D.
[tex]y(x)=6x\\\\y(2)=6*2=12[/tex]
This pair is a solution to this equation.
original amount 90$ new amount 84.50 what's the percent of change?
The percent of change from the original amount of $90 to the new amount of $84.50 is approximately a 6.11% decrease.
To calculate the percent of change, we need to determine the difference between the original and new amounts, then divide that difference by the original amount and multiply by 100 to get the percentage. In this case, the original amount is $90, and the new amount is $84.50. The difference between these two amounts is $90 - $84.50 = $5.50. We then take this change and divide it by the original amount: $5.50 / $90. Finally, to get the percent change, we multiply by 100:
($5.50 / $90) times 100 = 6.11%
The percent of change from the original amount of $90 to the new amount of $84.50 is approximately 6.11% decrease.

what is the circumference this unit circle
The circumference of a unit circle is calculated using the formula C = 2πr. For a unit circle, where the radius (r) is 1, the circumference (C) is 2π, approximately 6.2832.
The Circumference of a Unit Circle
In mathematics, the circumference of a circle is the distance around its perimeter. For a unit circle, which is a circle with a radius of 1, the formula to calculate circumference is given by C = 2πr, where r is the radius.
Since the radius of a unit circle is 1, substituting in the formula gives us:
C = 2π(1) = 2π
Thus, the circumference of a unit circle is 2π, which is approximately 6.2832 when using the value of π ≈ 3.1416.

The universal set is the set of rational numbers. S is the set of integers. Which represents Sc?The universal set is the set of rational numbers. S is the set of integers.
Which represents Sc?
Final answer:
To find Sc, which represents the complement of set S, we need to determine the elements that are in the universal set but not in S. Sc represents the set of all rational numbers that are not integers.
Explanation:
To find Sc, which represents the complement of set S, we need to determine the elements that are in the universal set but not in S. The universal set, in this case, is the set of rational numbers, which includes all numbers that can be expressed as a quotient or fraction. Set S is the set of integers, which includes the whole numbers and their negatives.
So, to find the complement of S, we need to consider all rational numbers that are not integers. This includes numbers with decimals or fractions that are not whole numbers. For example, 4.5, -3.2, and 1/2 would be in the complement of S.
Therefore, Sc represents the set of all rational numbers that are not integers.
China issued the largest stamp ever, 210mm Long and 65mm wide. Find the ratio of length to width
The ratio of the length to the width of the largest stamp ever issued by China, having dimensions of 210mm long and 65mm wide, is approximately 3.23:1 after dividing the length by the width.
Explanation:To answer the question about the ratio of the length to the width of the largest stamp ever issued by China, we need to follow a few simple steps. First, we have the dimensions of the stamp: 210mm long and 65mm wide.
Step 1: Identify the numbers given. In this case, the length of the stamp is 210mm, and the width is 65mm.
Step 2: To find the ratio of length to width, we need to divide the length by the width. So, 210 divided by 65 gives us approximately 3.23 (rounded to two decimal places).
Therefore, the ratio of the length to the width of the largest stamp ever issued by China, in simplest form, is approximately 3.23:1.

10 + x 12 = 12x + 10
a) commutative - addition
b) distributive
c) associative - multiplication
d) symmetric
e) commutative - multiplication
f) associative - addition
g) identity - addition
Answer:
The statement satisfied the expression 10 + x 12 = 12x + 10 is
Option (e) i.e commutative - multiplication and Option (a) i.e commutative - addition .
Step-by-step explanation:
Commutative Property
Let a, b be two numbers thus they satisfied the commutative property
i.e a + b = b + a
As given the expression.
10 + x ×12 = 12x + 10
First apply the Option (e) i.e Commutative - multiplication.
Thus expression becomes
10 + 12x = 12x + 10
Now apply the Option (a) i.e Commutative - addition.
Therefore the statement satisfied the expression 10 + x 12 = 12x + 10 is
Option (e) i.e commutative - multiplication and Option (a) i.e commutative - addition .
Write your own word problem, then create the slope intercept form equation.
The slope-intercept form equation for the word problem is [tex]\( y = \frac{3}{4}x + 1 \).[/tex]
Let's consider a word problem where a local gym charges a $1 sign-up fee and $3 for every hour of use. If we let [tex]\( x \)[/tex] represent the number of hours a member uses the gym and [tex]\( y \)[/tex] represent the total cost, we can write an equation in slope-intercept form.
The slope-intercept form of a linear equation is given by [tex]\( y = mx + b \)[/tex], where [tex]\( m \)[/tex] is the slope of the line and [tex]\( b \)[/tex] is the y-intercept.
In this scenario, the slope [tex]\( m \)[/tex] is the cost per hour, which is $3. The y-intercept [tex]\( b \)[/tex] is the initial sign-up fee, which is $1.
Therefore, the equation representing the total cost [tex]\( y \)[/tex] as a function of the number of hours [tex]\( x \)[/tex] used at the gym is:
[tex]\[ y = 3x + 1 \][/tex]
However, to make the equation more precise and to express the cost per hour as a fraction, we can write $3 as [tex]\( \frac{3}{1} \)[/tex] and then multiply both the numerator and the denominator by 4 to get [tex]\( \frac{3 \times 4}{1 \times 4} = \frac{12}{4} \)[/tex]. Simplifying the fraction [tex]\( \frac{12}{4} \)[/tex] gives us [tex]\( \frac{3}{4} \)[/tex]per hour.
Thus, the final slope-intercept form equation for the word problem is:
[tex]\[ y = \frac{3}{4}x + 1 \][/tex]
