Answer:
16/5 or 3 1/5 i think
Step-by-step explanation:
Answer:
x = 16/5.
As a decimal this would be x = 3.2.
Step-by-step explanation:
On the right, distribute the -1/4 to the (x - 8). Do this by multiplying -1/4 to each term in the parenthesis. Then, solve for x by combining like terms.

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)
Step-by-step explanation:
1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b
2. A proportional relationship has a constant rate of change.
ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.
3. A proportional relationship must pass through the origin in order to be a proportional relationship.
4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.
5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.
CODE WORD: 12 or Twelve is correct because 12 is the mean of all 5 answers.

what is the solution for
2x + y = 4
3x + 3y =9
Answer:
X=3 y = 5
Step-by-step explanation:
Step 1) Solve the first equation for y
Step 2) Substitute 3 x − 4 for y in the second equation and solve for x
Step 3) Substitute 3 for x in the solution to the first equation at the end of Step 1 and calculate y
The solution is:
x = 3 and y = 5 or ( 3 , 5 )

The drawing plan for an art studio shows a rectangle that is 19.2 inches by 8 inches. The scale in the plan is 4 in.: 5 ft. Find the length and width of the actual studio. Then find the area of the actual studio.
Tiana compares the length of a name on a nameplate to the number of letters in the name. She draws the scatterplot below, and then she plots and determines an equation for the trend line. Nameplates A graph has letters on the x-axis and length (inches) on the y-axis. A trend line goes through points (2, 5) and (4, 8). The regression equation is y = 1.47 x + 2.05. Based on the information above, which is the best estimate of the number of letters that a name contains if the nameplate is 6 inches long? 3 4 10 12
Answer:
3
Step-by-step explanation:
The best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.
What is a scatter plot?Scatter plots are graphs that represent individual points of data and are labeled with quantitative values on both coordinate axes, meaning that there is only one projection on the x-axis and one projection on the y-axis for each point.
It is given that, the regression equation is y = 1.47 x + 2.05.
The name's letter count is represented by variable x, whereas the name's length on a nameplate is represented by variable y.
The nameplate is 6 inches long, so y=6 and you can find x by doing the following:
6=1.4x+2.05
1.4x=6-2.05
1.4x=3.95
x=2.69
x≈3
Thus, the best estimate of the number of letters that a name contains is if the nameplate is 6 inches long will be 3. Option A is correct.

Solve for m: -8 = m/-10 - 16
Answer:
m = -80
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
-8 = m/-10 - 16
Step 2: Solve for m
Add 16 to both sides: 8 = m/-10Multiply -10 on both sides: -80 = mRewrite: m = -80Answer:
We have this equation:
-8 = m/-10 -1
We can add 8 at both sides:
-8 + 8 = m/-10 -16 + 8
0 = m/-10 -8
Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:
0 = m/-10 - 8*(-10)/-10
0 = m/-10 +80/-10
Now, we can delete all denominators
0 = m + 80
And we can say m = -80
Now, we can replace it to see if it's true:
-80/-10 - 16 = -8, so we know that's true
-80/-10 -16 = 8 - 16 = -8 ..
A car costing $125 000 may be paid for in any of the following ways:
Scheme A: By cash full payment.
Scheme B: A deposit of 40% of the cost plus 72 monthly payments of $1500. Which scheme is better A or B?
Show necessary working to justify your answer.
Answer:
Step-by-step explanation
Plan B
40% of 125000 = 40/100 * 125000 = 0.4 * 125000 = 50000
72 * 1500 = 108000
Total 158000
Plan A
125000
Difference 33000

The perimeter of a rectangle can be found using the formula 2l + 2w, where l represents the length of the rectangle and w represents the width of the rectangle. Find the perimeter of a rectangular swimming pool whose length is 32 feet and width is 20 feet.
Answer:
The perimeter is 104
Step-by-step explanation:
The formula for a peremeter is 2 * length + 2 * width.
Substitute the length and width for the given values.
2 * length + 2 * width
2 * 32 + 2 * 20
64 + 40
104
Klein opened a savings account that paid 5% simple interest with 6,000 in principal. If Klem left that money untouched in the account for ten years,then how much interest with he have earned?
Answer:
I= $3,000
Step-by-step explanation:
Giving the following information:
Klein opened a savings account that paid 5% simple interest with 6,000 in principal.
Number of periods= 10 years
To calculate the interest earned, we need to use the following formula:
I= P*r*t
P= principal
r= interest rate
t= time
I= 6,000*0.05*10
I= $3,000

Answer:
[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]
Hence, option (A) is true.
Step-by-step explanation:
Given the expression
[tex]-6x^2\left(3x^5\right)[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
i.e. [tex]x^2x^5=\:x^{2+5} \\[/tex]
so the expression becomes
[tex]-6x^2\left(3x^5\right)=-6\cdot \:\:3x^{2+5}[/tex]
[tex]\mathrm{Add\:the\:numbers:}\:2+5=7[/tex]
[tex]=-6\cdot \:3x^7[/tex]
[tex]\mathrm{Multiply\:the\:numbers:}\:6\cdot \:3=18[/tex]
[tex]=-18x^7[/tex]
Therefore,
[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]
Hence, option (A) is true.

Answer:
44 inches
Step-by-step explanation:
The sides of a rhombus are all the same length, so we have ...
AB = BC
3x -4 = 2x +1
x = 5 . . . . . . . . . add 4-2x
Then the side lengths are ...
3x -4 = 3·5 -4 = 11
Four of them total 4·11 = 44 inches.
