subtract: 3a ( a+ b+ c) - 2b (a- b+ c) from 4c (-a + b + c)
Answer:
4c^2 - 3a^2 -7ac +6bc -ab
Step-by-step explanation:
solve first 3a( a + b + c) - 2b ( a+ b +c)
which is = 3a^2 + 3ab + 3ac - 2ab - 2b^2 -2bc
there for 4c(-a + b +c) -( 3a^2 + 3ab + 3ac - 2ab - 2b^2 - 2bc)
= -4ac-3ac +4bc+2bc -3ab+2ab + 4c^2 -3a^2
=4c^2 - 3a^2 -7ac +6bc -ab

solve for n. n/-5= 7
Answer:
n = -35
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 equation
n/-5 = 7
Step 2: Solve for n
Multiply both sides by -5: n = -35Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -35/-5 = 7Divide: 7 = 7Here we see that 7 does indeed equal 7.
∴ n = -35 is a solution to the equation.
280 ml as a percentage of 140 l.
Answer:
280 ml as a percentage of 140 l is 0.2%
Step-by-step explanation:
Note that 1 liter = 1000 millilitersTo find a percentage of a number divide the number by the total and multiply the quotient by 100%∵ There is an amount of 280 ml
∵ The total amount is 140 l
→ Change the liter to milliliters using the 1st point above
∴ 140 l = 140 × 1000 = 140000 ml
∴ 140 l = 140,000 ml
→ Now divide the amount by the total, then multiply the quotient by 100%
∵ 280 ÷ 140,000 = [tex]\frac{1}{500}[/tex]
∵ [tex]\frac{1}{500}[/tex] × 100% = 0.2%
∴ 280 ml as a percentage of 140 l is 0.2%

Use a sample n = 500, = 0.90, and a 95% confidence level to construct a confidence interval estimate of the population proportion, p.
0.887 < p < 0.913
0.878 < p < 0.922
0.874 < p < 0.926
0.817 < p < 0.983
Answer:
0.874 < p <0.926
Step-by-step explanation:
The population proportion lies in the interval 0.8738 < p < 0.9262 with 95% confidence.
What is a confidence interval?The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.
Given, A sample having n = 500, p = 0.90, and we have to construct a 95% confidence interval.
We know the confidence interval for a population proportion is,
CI = [tex]P \pm Z_\frac{\alpha}{2}\sqrt{\frac{P(1 - P)}{n}}[/tex].
CI = 0.9 ± 1.96×{√(0.9×0.1)/500}.
CI = 0.9 ± 1.96×√(0.09/500).
CI = 0.9 ± 1.96×0.0134.
CI = 0.9 ± 0.0262.
Therefore, 0.9 - 0.0262 < p < 0.9 + 0.0262.
0.8738 < p < 0.9262.

Answer: 62
Step-by-step explanation:
Every triangle’s angles add up to 180. since it’s a right triangle one of the angles is 90 degrees and the other is 28 degrees. so then you have to find the other angle which would made it add up to 180. which is 62.
28+90=118

please help me
=======================================================
Explanation:
The information that m || n is not needed or used, so I'm not sure why your teacher put that in there.
The angles shown are a linear pair. They are adjacent and they are supplementary. They form a straight angle.
Supplementary angles add to 180.
(x-17)+(5x-1) = 180
x-17+5x-1 = 180
(x+5x)+(-17-1) = 180
6x-18 = 180
6x = 180+18
6x = 198
x = 198/6
x = 33
---------
Extra info:
if x = 33, then,
x-17 = 33-17 = 165x-1 = 5*33-1 = 165-1 = 164Adding the angles gives 16+164 = 180 which helps confirm our answer.

The length of a cell phone is 1.21.2 inches and the width is 4.64.6 inches. The company making the cell phone wants to make a new version whose length will be 1.141.14 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answer:
The width of the new phone will be 4.37 inches
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value.
The original length of a cell phone was L=1.2 inches and the original width was 4.6 inches.
A new version of the cell phone is to be released with proportional dimensions with respect to the original cell phone.
We are given the length of the new phone L'=1.14 inches. The ratio of the lengths is 1,2/1.14=1.053.
The new width should be W'=4.6/1.053=4.37 inches
The width of the new phone will be 4.37 inches

It's not a linear equation, but its grapg is a straight line.
It is a linear equation, and its graph is a straight line.
It's not a linear equation and its graph is not a straight line.
it's a linear equation, but the graph is not a straight line
Answer:
The given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
Step-by-step explanation:
Given the equation
y = -2x +30
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept
The graph of y=mx+b is a straight line as it is the line equation.Writing the equation in the slope-intercept form
y = -2x +30
y = mx + b
Thus,
m = -2
b = 30
Thus, the given line y = -2x +30 is a straight line as it is written in the
form y = mx + b.
The graph of the line y = -2x +30 is also straight and attached below.
