-6= n/2-10 what is n?
Answer:
8
Step-by-step explanation:
8/2 equals 4 minus 10 is -6
Answer:
-6= n/2 -10
-12=n-20
-12-n=-20
-n=-20+ 12
-n=-8
n=8
Step-by-step explanation:
1. multiply both sides of the equations by 2
2.Move the N varaiableto the left hand side and change its sign
3. Calculate the sum of -20+12
4. change the signs from negative N to positive N giving you the value of 8
n=8
Solved.

Can someone please help me ASAP!!?
Answer:
Option A
Step-by-step explanation:
Domain is the set of x values or input values of a function.
Range is the set of y values or output values of a function.
Given relation is,
2x + y = 4
Set if input values of domain → {-5, 0, 6}
Table for the input - output values,
x -5 0 6
y 14 4 -8
Therefore, range of the given relation will be the set of output values.
{14, 4, -8}
Option A is the answer.

a student throws a baseball with a speed of 8m/s and a kenetic energy of 25J.what is the mass of the baseball
Answer:
25/32 kg
Step-by-step explanation:
The kinetic energy K of a body in motion measured in joules is given as
K = 1/2 mV^2
Where n is the mass in kg and V is the speed in m/s
Hence given that K is 25J and speed V is 8 m/s,
25 =1/2 * m * 8^2
25 = m *32
Divide both sides by 32
m = 25/32 kg
A car dealership has SUVs and sedans in a ration of 5:9. How many sedans does the car dealership have if there are 140 SUVs
To solve this, all you need to do is compare the ratio to the amount of SUVS there are.
5/9 (SUVs to sedans)
140/? (SUVs to sedans)
140 ÷ 5 = 28
9 x 28 = 252
140/252
There are 252 sedans in the car dealership! :D
Answer:
252 Sedans

Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if necessary.
C=24x+80
R=44x
Break Even point (_ , _)
Answer:
Please check the explanation.
Step-by-step explanation:
Given
C=24x+80
R=44x
To determine
What is the break-even point?
Given that
C represents the cost in dollars
R represents the revenue in dollars.
At the break-even point Cost (C) equals Revenue (R), so
R = C
44x = 24x+80
44x-24x = 80
20x = 80
divide both sides by 20
20x/20 = 80/20
x = 4
Thus, at x = 4 the value of Cost (C) equals Revenue (R).
i.e.
C = 24x+80 = 24(4)+80 = $176
R = 44x = 44(4) = $176
Answer:
(4, 176)

I am having trouble on algebraic expressions and numerical expression what is the easiest way to solve my problem and im in 6 th grade
Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.
Step-by-step explanation:
First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).
For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.
While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.
Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.
For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.

Step-by-step explanation:
Mark's favorite tree is a large oak
tree in his front yard. Mark wanted to
know how tall the tree is. At the
same time of day, he measured the
length of his shadow and the length
of the shadow cast by the tree. Mark,
who is 5 feet tall, cast a shadow 10
feet long. He found that the tree's
shadow was 140 feet long. How tall is
the tree?
Answer: The shadow of the tree is 280 feet long.
Step-by-step explanation:
We can use a ratio to solve this:
Use the Height to shadow for each. This works because the fractions must reduce to the same equivalent.
5/10 = 140/x
We can see that 5/10 is 1/2, so we need another fraction using 140 as the numerator that is equal to 1/2. That's easy here: Multiply 140 × 2 to get the new denominator, 280 that replaces x. That is the length of the shadow.
If you have a less obvious ratio, you can use Cross Multiplication to solve the unknown value in the ratio:
5/10 = 140/x Cross multiply the numerator of the left side times the denominator on the right side, and the denominator on the left side by the numerator on the right side:
5 × x = 10 × 140
5x = 1400 Divide both sides by 5 (the 5s "cancel" on the left)
5x/5 = 1400/5
x = 280
I hope this helps, especially when you see more questions like this in the future.

Best Buy is having a HUGE sale. All items are 60% off. How much will you pay for a tv that originally cost $1200 including 5% sales tax?
Answer:
$480
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Original cost including sales tax = $1,200
Discount = 60%
So, we can calculate the cost of TV after discount by using following formula:
Cost of TV after discount = $1,200 - ( $1,200 × 60%)
= $1,200 - $720
= $480
Hence, Cost of TV after discount is $480.
