Evaluate the expression 2n  6 if n = 16.
Answers
Answer:
[tex]26[/tex]
Stepbystep explanation:
[tex]2n6[/tex]
Given that:
[tex]n=16[/tex]
To evaluate the expression, we must simply substitute the given value of [tex]n[/tex], which is [tex]16[/tex], for [tex]n[/tex]:
[tex]2(16)6[/tex]
Multiply:
[tex]326[/tex]
Subtract:
[tex]26[/tex]

To check your work, simply set the given expression equal to our solution, [tex]26[/tex]:
[tex]2n6=26[/tex]
Add [tex]6[/tex] to both sides of the equation:
[tex]2n=32[/tex]
Divide both sides of the equation by the coefficient of [tex]n[/tex], which is [tex]2[/tex]:
[tex]n=16[/tex]
Since it matches the given value of [tex]n[/tex], our solution is correct!
Answer:
26
Stepbystep explanation:
This is the answer because:
1) First, we have to substitue the value that stand for n into the equation:
2(16)  6
2) Next, we have to follow the order of operations in order to find the answer:
1. 2 x 16 = 32
2. 32  6 = 26
Therefore, the answer is 26.

Which of these units would be best to measure the length of our classroom?
1. meters
2. centimeters
3. liters
4. kilometers
5. millimeters
Answers
Answer:
1. meters
Stepbystep explanation:
The smallest unit given in the choice is millimeters. Then comes the centimeters, then meters, and the kilometers.
Liters is used to measure the volume of a liquid. For example we get 1 liters of milk but not 1 kilometers of milk.
The kilometers has a 1000 meters and
1m= 100 cm
1cm = 10mm
The kilometers is quite a large space and usually long distances such as length between 2 towns is measured in kilometers.
The area of the room or length is usually measured in feet but since feet is not given here.
1 feet = 0.3048 m
so the most suitable selection would be meters.
The millimeters is very small. 1 cm has 10 mm. A foot consists of 30.48 cm.
So meters is used.
What is the xvalue in the solution to this system of linear equations?
2x − y = 11
x + 3y = −5
−3
−1

4
Answers
Answer:
(7, 3)
Stepbystep explanation:
Solve the system of linear equations
2x − y = 11
x + 3y = −5
by elimination by addition and subtraction. Multiply the second equation by 2, obtaining
2x  y = 11
2x  6y = 10

7y = 21, which yields y = 3
Knowing that y = 3, we can now find the value of x. Let's use the first equation for this purpose. Substituting 3 for y, we get:
2x  (3) = 11, or
2x = 11 + 3, or 2x = 14. Thus, x = 7.
The solution is (7, 3).

A table saw is on clearance for 20% off. If the sale price of the table saw is $380, what was the original price? Justify your solution. Round to the nearest cent if necessary.
Answers
20% off means it is selling for 80% of the original price ( 100%  20% =80%)
Divide the sale price by 80% as a decimal:
380/0.80 = 475
The original price was $475
Justify:
Multiply the original price by 20% and subtract:
475 x 0.20 = 95
47595 = $380 which is the sale price.

Answers
Answer:
You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. For decreases in temperature, the result is negative.

Help me please I'm so stuck lol 15 pts.!!

Answer:
r = 0.1
Stepbystep explanation:
Constant proportionality or slope(rate of change) is found by Y divided by X.
1.4(y) ÷ 14(x) = 0.1(slope)
1.6(y) ÷ 16(x) = 0.1(slope)
2.1(y) ÷ 21(x) = 0.1(slope)
Check Work:
14 x 0.1 = 1.4
16 x 0.1 = 1.6
21 x 0.1 = 2.1
Answer:
1/10.
Stepbystep explanation:
The proportionality equation is given to you: [tex]y = rx[/tex]
Next, plug in the given [tex]x[/tex] and [tex]y[/tex] variables into the equation:
When: [tex]x = 14[/tex] & [tex]y = 1.4[/tex]
[tex]1.4 = r(14)\\1.4 = 14r\\(1.4)/14 = (14r)/14\\1.4/14 = r\\r = 0.1[/tex]
When: [tex]x = 16[/tex] & [tex]y = 1.6[/tex]
[tex]1.6 = r(16)\\1.6 = 16r\\(1.6)/16 = (16r)/16\\r = 1.6/16\\r = 0.1[/tex]
When: [tex]x = 21[/tex] & [tex]y = 2.1[/tex]
[tex]2.1 = r(21)\\[/tex]
[tex]21r = 2.1\\(21r)/21 = (2.1)/21\\r = 2.1/21\\r = 0.1[/tex]
r = 0.1 in all of the given, ∴ 0.1 is your answer. Change the decimal into a fraction:
0.1 = 1/10
1/10 is your answer.

What is a Vector?
Vector is a quantity that has both magnitude and direction.
The scalar projection of a onto b is given by
[tex]\dfrac {a.b}{b}[/tex]
a.b = a b cos[tex]\rm \theta[/tex]
a.b = 21 *44 *(7/12)
a.b = 539
The dot product of a and b is 539.
The scalar projection is
= 539 / 44
= 49/4
Therefore, the dot product is 539, and the scalar projection of a onto b is 49/4.
