When the sum of 3 times a number and 4 is increased by 6, the result is 2 times a number decreased by 14. Determine whether each step is a correct step for writing and solving this equation by selecting Yes or No. A Write the equation 3n + 4 + 6 = 2n – 14. Yes No B Write the equation 3(n + 4) + 6 = 2(n – 14). Yes No C Combine like terms. Yes No D Subtract 2n from each side. Yes No E Add 10 to each side. Yes No F Subtract 10 from each side. Yes No
Answer:
A. Yes
B. No
C. Yes
D. Yes
E. No
F. Yes
Step-by-step explanation:
A Write the equation 3n + 4 + 6 = 2n – 14. Yes
B Write the equation 3(n + 4) + 6 = 2(n – 14). No
C Combine like terms. Yes
D Subtract 2n from each side. Yes
E Add 10 to each side. No
F Subtract 10 from each side. Yes
Solution:
sum of 3 times a number and 4 is increased by 6, the result is 2 times a number decreased by 14
Let the number = n
{(3 * n) + 4} + 6 = (2 * n) - 14
3n + 4 + 6 = 2n - 14
3n + 10 = 2n - 14
3n + 10 - 2n = 2n - 14 - 2n
n + 10 = -14
Subtract 10 from each side
n + 10 - 10 = -14 - 10
n = -24
Answer: A. Yes B. No C.Yes D. Yes E. No F. Yes

4x²- 12x + 9 = 5
Answer:
A & B
Step-by-step explanation:
4x²- 12x + 9 = 5
4x²- 12x + 4 = 0
devided by 4
x²-3x+1=0
x = (3 ± √9-4)/2 = (3±√5)/2

x -y = 3
solve for y
Answer:
y=x−3
Step-by-step explanation:
x−y=3
Step 1: Add -x to both sides.
x−y+−x=3+−x
−y=−x+3
Step 2: Divide both sides by -1.
−y/−1=−x+3/1
y=x−3

A 23.9 foot tall streetlight casts a shadow that is 17.7 feet long. How long is the shadow cast by a nearby parking meter that is 3.6 feet high?
Answer:
2.67 feet long
Step-by-step explanation:
Create a proportion where x is the length of the parking meter's shadow:
[tex]\frac{23.9}{17.7}[/tex] = [tex]\frac{3.6}{x}[/tex]
Cross multiply and solve for x:
23.9x = 63.72
x = 2.67
So, the parking meter's shadow is approximately 2.67 feet long

This scatter plot shows the relationship between the average weight and average heart rate for 11 different animals. The line of best fit is shown on the graph. Select True or False for each statement based on the graph.
Answer:
See below
Step-by-step explanation:
1) I would lean more toward false because most of the points aren't in a straight line
2) That is most likely true because the line of best fits appears to be hitting that point
3) That is false because point D is located on the line of best fit which means it isn't an outlier
find the mean median and mode. 63, 40, 51, 70, 36, 21, 51, 28, 19
The mean, median, and mode of the data will be 41.111, 40, and 51 respectively.
What are statistics?Statistics is the study of collection, analysis, interpretation, and presentation of data or discipline to collect and summarise the data.
The data is given below.
63, 40, 51, 70, 36, 21, 51, 28, 19
Arrange the data in ascending order, then we have
19, 21, 28, 36, 40, 51, 51, 63, 70
Then the mean of the data is given as,
Mean = (19 + 21 + 28 + 36 + 40 + 51 + 51 + 63 + 70) / 9
Mean = 379 / 9
Mean = 42.11
The median of the data is the middle term of the data which is 40.
The mode is 51 because the number frequency of 51 is the highest.

The sum of two numbers is 38. The greater number is 8 more than the other number. Find each number.
Step-by-step explanation:
Answer:
23 and 15
Step-by-step explanation:
Create a system of equations where x is the greater number, and y is the smaller number.
x + y = 38
x = y + 8
Solve by substitution, by substituting the second equation into the first one, then solving for y:
x + y = 38
(y + 8) + y = 38
Add like terms and solve for y:
2y + 8 = 38
2y = 30
y = 15
Add 8 to this, to find the greater number:
15 + 8
= 23
So, the numbers are 23 and 15.

Part A: Create a scatter plot to represent the data shown above. Sketch the line of best fit. Label at least three specific points on the graph that the line passes through. Also include the correct labels on the x-axis and y-axis. Part B: Algebraically write the equation of the best fit line in slope-intercept form. Include all of your calculations in your final answer. Part C: Use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.
It is to be noted that the scatter plot that represent the above data is attached accordingly.
What is a scatter plot?A scatter plot is a graph in which the data of two variables are displayed along two axes, and any association is revealed by the pattern of the resultant dots.
Remember Scatter plot is a type of x-y graphX is the horizontal line and will be the AgeY is the vertical lien and will be Weight
What is the Algebraic equation of the best fit line in slope-intercept form? [Part B]
Slope-intercept form is y = mx + b
m is the gradient of the line, determined by calculating "change of y divided by change of x"
Age 2 and weight 32 would be the point (2, 32) on the graphAge 8 and weight 60 is the point (8, 60) in the graphTo compute for the gradient (m) we say:
(60 - 32)/(8-2)
= 28/6
m = 4.667
Next we calculate for b
The point on the graph where the line crosses the vertical line is known as the y-intercept, or b. (y-axis).
Put one of the graph's points, say (2, 32), and the amount of m you just computed into the slope-intercept form to calculate b.
That is:
32 = m(2) + b
Recall that m = 4.667
Hence 32 = 4.667 * 2 + b
32 = 6.667 + b
b = 32 - 6.667
b = 25.33
Using the equation for the line of best fit what is the approximate weight of the little girl at an age of 14 years old? [Part C]Given that we have the figures for m and b,
Recall that the function is: y = mx + b; and that
If x = 14 years, then
y = 4.667 * 14 + 25.33
y = 90.668
y ≈ 91 kg.

A box contains 12 cereal bars. The empty box weighs 1.75 oz. The box and the bars weigh 18.55 oz. What is the weight of each cereal bar?
please provide the answer and the equation
Answer:
Each cereal bar is 1.4 ounces
Subtract the weight of the empty box from the 18.55 (because that's the weight of the box AND the cereal)
You are then left with 16.8 ounces, which is just the weight of the 12 cereal bars.
To find the weight of one cereal bar, assuming that all cereal bars weigh the same, you need to divide 16.8 by 12.
So that results in each cereal bar weighing 1.4 ounces

The principal P is borrowed at a simple interest rate r for a period of time t. Find the loan's future value A, or the total amount due at time t. Round answers to the nearest cent. P=$2000, r=%6, T=6 years
Answer:
$2720
Step-by-step explanation:
Given data
Principal=$2000
r= %6
T= 6 years
The expression for the final amount is
A= P(1+rt)
A=2000(1+0.06*6)
A=2000(1+0.36)
A=2000*1.36
A=2720
Hence the amount is $2720
