solve for n -2 = -n + 8
Answer:
N=10
Step-by-step explanation:
-2n=-n+8
subtract 8 on both sides
-10/-n= -n/-n
the variables cancel out and you divide -10 with -1 because your variable is always 1 giving you the answer

Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{n = 5}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{n - 2 = - n + 8}[/tex]
Move n to left hand side and change it's sign
Similarly, move 2 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{n + n = 8 + 2}}[/tex]
Collect like terms
[tex] \longrightarrow{ \sf{2n = 8 + 2}}[/tex]
Add the numbers: 8 and 2
[tex] \longrightarrow{ \sf{2n = 10}}[/tex]
Divide both sides by 2
[tex] \longrightarrow{ \sf{ \frac{2n}{2} = \frac{10}{2}}} [/tex]
Calculate

Tina is saving to buy a notebook computer. She has two options. The first option is to put $300 away
initially and save $20 every month. The second option is to put $100 away initially and save $40 every
month. After how many months would Tina save the same amount using either option? How much
would she save with either option?
After
months, Tina will save $
with either option.

The length of a rectangle is (x-8)units, and its width is (x+11) units. Which expression can represent the area of the rectangle?
Answer:
(x²+3x-88) square units
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
length of a rectangle is (x-8)units
Its width is (x+11) units.
Required
Expression for the area of the rectangle
Substituting the given function into the formula.
Area of the rectangle = (x-8)(x+11)
Area of the rectangle = x(x)+11x-8x-88
Area of the rectangle = x²+3x-88
Hence the expression that represents the area of the rectangle is x²+3x-88 units²
Answer:
x² + 3x - 88

The area of a football field is 57,600 square feet. If the width of the field is 4/9 the length, what is the length of the football field ?
Answer:
360 ft
Step-by-step explanation:
GivenArea = 57600 ft²Length = xWidth = 4/9xSolutionA = lwx*4/9x = 576004/9x²= 57600x² = 57600*9/4x² = 129600x = √129600x = 360 ftA rectangular yard measuring 32ft by 50ft is bordered (and surrounded) by a fence. Inside, a walk that is 3ft wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.
Answer:
528 feet squared
Step-by-step explanation:
the yard has a width of 32 feet and a length of 50 feet. -- area of the yard is 1600 ft sq. The walkway is 3 feet wide throughout the fence, meaning you add 6 to 32 and 6 to 50 to get your measurements for the yard + fence area. -- is equal to 2128
Then you subtract the total fence + yard area from the yard area -- 2128 - 1600 which equals 528 feet sq.

What is the equation of the line that is parallel to Y= -2/3x+4 and that passes through (-2, -2)
Answer:
y = -2/3x-10/3
Step-by-step explanation:
Y= -2/3x+4
This is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is -2/3
Parallel lines have the same slope
y = -2/3 x+b
Substitute the point into the equation
-2 = -2/3 (-2) +b
-2 = 4/3 +b
Subtract 4/3 from each side
-6/3 -4/3 = 4/3 -4/3 +b
-10/3 = b
y = -2/3x-10/3

The measure of the supplement of an angle is 36 less than the measure of the angle. Find the measures of the angles.
Answer:
∠1 → 108
∠2 → 72
Step-by-step explanation:
Supplementary angles add up to a total of 180° (two angles is a pair). So:
∠1+∠2=180°
∠1 → supplement
∠2 → 36 less than the supplement
Create an equation, using x as angle 1 and y as angle 2:
[tex]x+y=180[/tex]
Insert the given values:
[tex]x+(x-36)=180[/tex]
Solve for the value of x. Simplify parentheses:
[tex]x+x-36=180[/tex]
Simplify addition:
[tex]2x-36=180[/tex]
Add 36 to both sides:
[tex]2x-36+36=180+36\\\\2x=216[/tex]
Isolate the variable. Divide both sides by 2:
[tex]\frac{2x}{2}=\frac{216}{2}\\\\ x=108[/tex]
The value of x is 108. Insert this into the equation above:
[tex]x+y=180\\\\108+y=180[/tex]
Solve for y. Subtract 108 from both sides:
[tex]108-108+y=180-108\\\\y=72[/tex]
The value of y is 72.
Therefore:
∠1 → 108
∠2 → 72
:Done
*Check:
Insert the values into an equation set to 180 to determine if true:
[tex]108+72=180\\\\180=180[/tex]
Subtract 108 by 72 to see if the difference is 36:
[tex]108-72=36\\36=36[/tex]
The given values are true.
Supplementary angles add up to [tex]180^o[/tex]
The angles are 72 and 108
Let the angles be x and y.
Such that:
[tex]y = x - 36[/tex]
So, we have:
[tex]x + y = 180[/tex] --- sum of supplementary angles
Substitute [tex]y = x - 36[/tex]
[tex]x + x - 36 = 180[/tex]
[tex]2x - 36 = 180[/tex]
Collect like terms
[tex]2x = 36 + 180[/tex]
[tex]2x = 216[/tex]
Divide by 2
[tex]x = 108[/tex]
Recall that:
[tex]y = x - 36[/tex]
[tex]y = 108 - 36[/tex]
[tex]y = 72[/tex]
Hence, the angles are 72 and 108

Answer:

Step-by-step explanation:
An equation is a way of writing two expressions connected by an equal sign.
If the total cost of leasing a car in m month is given by an equation:
c = 450m + 1500
The total cost in dollars, of leasing a car for 32 months is $15,900.
What is an equation?An equation is a way of writing two expressions connected by an equal sign.
Example:
2x = 3x + 5 is an equation.
We have,
The cost of leasing a new car per month = $450
Down payment = $1500
The total cost of the lease is given as:
c = 450m + 1500
m = number of months.
The total cost of the car for leasing in 32 months:
c = 450 x 32 + 1500
c = 14,400 + 1500
c = 15,900
Thus,
The total cost in dollars, of leasing a car for 32 months is $15,900.

A dot-com company ships products from three different warehouses (A, B, and C). Based on customer complaints, it appears that 3% of the shipments coming from A are somehow faulty, as are 5% of the shipments coming from B, and 2% coming from C. suppose a customer is mailed an order and calls in a complaint the next day. What is the probability the item came from Warehouse C
Answer:
The probability of getting defective product from warehouse C is 0.3448
Step-by-step explanation:
Missing question "Assume that Ware houses A, B and C ship 30%, 20% and 50% of the dot-com's sales respectively.
P(A) = Probability of product that comes from warehouse A
P(B) = Probability of product that comes from warehouse B
P(C) = Probability of product that comes from warehouse C
P(A) = 30% = 0.30, P(B) = 20% = 0.20, P(C) = 50% = 0.50
Let D denotes the number of defective products
P(D|A) = 3% = 0.03
P(D|B) = 5% = 0.05
P(D|C) = 2% = 0.02
The probability of getting defective product from warehouse C is as below using the Bayes Rule
P(C|D) = P(D|C) P(C) / P(D|A)P(A) + P(D|B)P(B) + P(D|C)P(C)
P(C|D) = 0.02 * 0.50 / (0.03*0.30) + (0.05*0.20) + (0.02*0.50)
P(C|D) = 0.01 / 0.009 + 0.01 + 0.01
P(C|D) = 0.01 / 0.029
P(C|D) = 0.3448
Therefore the probability of getting defective product from warehouse C is 0.3448.
