Justify each step in solving the equation 4x=7(x-3) by writing a reason for each statement.
Statement Reason
1. 4x=7(x-3) 1. Given
2. 4x=7x-21 2.?
3. -3x=-21 3.?
4. x=7 4. ?
Fill in the blanks.
Step One: The distributive property
4x = 7x - 21
Step Two: Subtraction of equals from both sides of the equation.
4x - 7x = 7x - 7x - 21
Step Three
Collecting like terms
-3x = - 21
Step Four
Divide by - 3: division of equals.
-3x/-3 = -21/-3
x = 7

Which answer is a reasonable estimate to the following problem? 194 x 476
To estimate the product of 194 x 476, we round each number to the nearest hundred and multiply. After rounding, the multiplication is 200 x 500, which equals 100,000. This is a reasonable estimate for the multiplication problem.
Explanation:The subject of this question is Mathematics, and the grade level appears to be Middle School. The student is asking for a reasonable estimate of the product of 194 and 476.
To estimate the product of 194 x 476, we should round each number to a convenient figure before multiplying. Both numbers round to the nearest hundred, with 194 rounding down to 200 and 476 rounding up to 500.
The estimate calculation would therefore be:
Round 194 down to 200 (because it is closer to 200 than to 300).Round 476 up to 500 (because it is closer to 500 than to 400).Multiply the rounded numbers: 200 x 500.When we multiply these rounded figures, we get:
200 x 500 = 100,000
This is a reasonable estimate for the product of 194 x 476.

In the lunch room at your school, 5 people can sit at one table. If you put two tables together, 8 people can sit. If you put three tables together, 11 people can sit. How many people can sit if you put 20 tables together?
Based on the pattern, with each added table, 3 more people can sit. Now, let's see, how many people can sit when we put 20 tables together.
1. First, count the number of 'extra' tables after the first one. With 20 tables in total, we subtract 1 for the initial table to obtain 19 extra tables.
2. We know that for each extra table, 3 more people can sit. So, we then multiply the 19 extra tables by 3, which results in 57.
3. Recall that with the first table, 5 people could sit.
4. To get the total number of people that can sit, we then add the calculated extra seats, which is 57, to the initial 5 seats. So, 57 + 5 equals 62.
So, when you put 20 tables together, 62 people can sit according to the pattern we have noticed.
How do you right the decimal equivalent for 117 151/200
Answer:
117.775
Step-by-step explanation:
Divide 151 by 200
117.775
To convert the mixed number 117 151/200 to a decimal, divide the numerator by the denominator and we get 0.755.
Explanation:To write the decimal equivalent of a mixed number like 117 151/200, we first convert the whole number part to a fraction by adding a denominator of 1. So, 117 can be written as 117/1. Then, we find a common denominator for the numerator and denominator of the fraction part, which in this case is 200. When we add the whole number part to the fraction part, we get 117 151/200.
To convert this mixed number to a decimal, we divide the numerator by the denominator. In this case, 151 divided by 200 gives us 0.755.

The most general proccedure for this type of problems is the following:
For a quadratic function of the following form [tex]f(x)=x^2+bx+c[/tex]; where b and c are real numbers.
1) Identify the value that accompanies the x, that is, the value "b"
2) Divide the value of b by 2 and then square it: [tex](\frac{b}{2})^2[/tex]
3) Add and subtract in the function the value of [tex](\frac{b}{2})^2[/tex]
4) Write the complete function of the form [tex]f(x) = (x+\frac{b}{2})^2-(\frac{b}{2} )^2+c[/tex]
For the function presented [tex]f(x)=x^2 +12x+6[/tex] the result is as follows:
1) The value of b is 12
2) [tex](\frac{12}{2} )^2=36[/tex]
3) [tex]f(x)=(x^2+12x+36)-36+6[/tex]

[tex]e^{3x}=12\\\\3x=\ln 12\\\\x=\dfrac{\ln 12}{3}\approx0.83\\\\\\[/tex]
Answer:
x=0.83
Step-by-step explanation:
Given: [tex]e^{3x}=12[/tex]
We are given an exponential equation and to solve for x.
[tex]e^{3x}=12[/tex]
Taking ln both sides
[tex]\ln e^{3x}=\ln 12[/tex]
[tex]3x\ln e=\ln 12[/tex] [tex]\because ln a^m=m\ln a[/tex]
[tex]3x=\ln 12[/tex] [tex]\because \ln e=1[/tex]
[tex]x=\dfrac{\ln 12}{3}[/tex] [tex]\text{divides both sides by 3}[/tex]
The exact value of x is [tex]\dfrac{\ln 12}{3}[/tex]

A leaf hangs from a branch 12 feet in the air. It falls to the ground at a rate of 0.25 feet per second. Which graph could represent the leaf’s height in feet as a function of time, in seconds, after leaving the branch?
The fourth graph is showing the correct relation between the leaf’s height in feet as a function of time, in seconds.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.
The height is 12 feet and the rate of falling of leaf is 0.25 feet per second.
Check for the 20th-second leaf's position.
Position = 0.25 x 20 = 5 feet
So in 20 seconds leaf will travel 5 feet so the height of the leaf from the ground is,
H = 12-5 = 7 feet
The fourth graph is showing the position at 7 feet in 20 seconds.
Therefore, the fourth graph is showing the correct relation between the leaf’s height in feet as a function of time, in seconds.

Match the conditional statement p→q, the converse q→p, the inverse ~p→~q, and the contrapositive ~q→~p in words.
Let p be “two angles are supplementary” and let q be “the measures of the angles sum to 180°.”
For the text answers:
conditional - If 2 lines are supplementary then the measure of the angles sum is 180
converse - If the measure if the angle sum is 180 then the 2 lines are supplementary
inverse - If 2 lines are not supplementary then the measure if the angle sum is not 180
contrapositive - If the measure if the angle sum is not 180 then 2 lines are not supplementary.
answer to the picture one:
conditional - If you do all your math homework then you will do well on the test.
converse - If you do well on the test then you do all your math homework
inverse - If you do not do all your math homework then you will not do well on the test.
contrapositive - If you do not well on the test then you did not do all your math homework
The conditional statement reads as if two angles are supplementary, then their measures sum to 180 degrees. Its converse flips this relationship around. The inverse and contrapositive negate the original and converse statements, respectively.
Explanation:In this context, the conditional statement p→q would read: if two angles are supplementary, then the measures of the angles sum to 180°. The converse, q→p, would be: if the measures of the angles sum to 180°, then the angles are supplementary.
The inverse, ~p→~q, changes the original statement to: if two angles are not supplementary, then the measures of the angles do not sum to 180°. Finally, the contrapositive, ~q→~p, would be: if the measures of the angles do not sum to 180°, then the angles are not supplementary. These variations of the original conditional statement allow us to analyze the relationship between the angles and their measures in different ways.
