Sam wanted to find the difference 10 -(-6).
He said he would add the opposite. This is what he did:
10 - (-6) = 10 + (-6) = 4
Was Sam's thinking correct? Explain. In your explanation, describe how to add the
opposite and use a number line to find the value of 10 -(-6).
Given:
The expression is [tex]10 - (-6)[/tex].
Sam's calculation is [tex]10 - (-6) = 10 + (-6) = 4[/tex]
To find:
Whether Sam's thinking correct or not.
Solution:
We have,
[tex]10 - (-6) = 10+6[/tex] [tex][\because (-)(-)=(+)][/tex]
[tex]10 - (-6) = 16[/tex]
[tex]10 - (-6) \neq 4[/tex]
Therefore, Sam's thinking was incorrect.
On number first we have to move 10 units from 0 in positive direction after that negative sign means move in left direction.
But we have 2 negative signs so we need to move 6 units more on positive or right direct as shown below.

Andre drew a plan of the courtyard at a scale of 1 to 60 on his drawing one side of the courtyard is 2.75 inches what is the actual measurement of the side of the courtyard express your answer in inches
Answer:
165 inches
Step-by-step explanation:
The scale is 1 to 60, so real measurements are 60 times bigger than drawing measurements.
2.75 inches * 60 = 165 inches
The distance between two communication towers is 12.654 miles. What is this distance rounded to the nearest tenth of a mile?
Answer:
12.7 miles
Step-by-step explanation:
Note the place values:
12.654
1 (tens value)
2 (ones value)
.
6 (tenths value)
5 (hundredths value)
4 (thousandths value)
~
You are rounding to the nearest tenths value. Note that when rounding, you look at the value directly next to the one you are solving for. If the digit is 5 or greater, round up. If it is 4 or less, round down.
In this case, the hundredths value is a 5, so round up.
12.654 miles rounded to the nearest tenths value is 12.7
12.7 miles is your answer.
What is the value of the expression below when x
3 and y = 8?
6x + 10y
Answer:

If y varies directly as x, and y is 400 when x is r and y is r when x is 4, what is the numeric constant of variation in this
relation?
10
40
100
198
Answer:
10
Step-by-step explanation:
If there is a direct relation between two variables x and y then it can be represented as
y = kx ,
where y is dependent variable
x is independent variable
k is constant of variation
_____________________________
First condition
y = 400
x = r
using y = kx then relationship will be
400 = kr
finding k here
k = 400/r
Second condition
y = r
x = 4
using y = kx then relationship will be
r = 4k
finding k
k = r/4
since in both condition equation is same
thus, value of k will also be same
thus,
400/r = r/4
=> 400*4 = r*r
=> 1600 = r^2
[tex]\sqrt{r^{2} } = \sqrt{1600} \\r = 40[/tex]
Thus, 40 is the value of r
k = r/4 = 40/4 = 10
Thus, constant of variation is 10 which is correct choice.
To cross validate
k = 400/r = 400/40 = 10
Answer:
40
Step-by-step explanation:
[tex]\frac{r}{400}[/tex] = [tex]\frac{4}{r}[/tex]
cross multiply - 400*4 = 1600 and r*r = r^2
square both - √1600 = 40

When a number is doubled and then added to 24,the result is 49
Answer:
Algebraic equation ; 2x+24 =49
x = 12.5
Step-by-step explanation:
Let the unknown number be x
[tex]2(x) +24 =49\\\\2x +24 =49[/tex]
Collect like terms and simplify
[tex]2x =49-24\\2x =25\\[/tex]
Divide both sides of the equation by 2
[tex]\frac{2x}{2} = \frac{25}{2} \\\\x = 12.5[/tex]

2. Toby Vail.
Annual gross pay of $18,200.
Personal exemptions of $1,500.
State tax on first $3,000: 1.5 percent.
Tax on amount over $3,000:
3 percent.
Answer:
Toby Vail wis taxed for $456
Step-by-step explanation:
First, we make the deductions:
gross pay 18,200 - 1,500 deductions = 16,700 taxable income
Now, we make the tax-calculations:
first $3,000 x 0.015 = $ 45
above:
(16,700 - 3,000) x 0.03 = $411
Total tax levied from the State: $45 + $411 = $456
Notice how the tax is calcualte in brackets to solve for the different taxation rate at different income levels.

explain how to use a graph of the function f(x) to find f(3)
Answer:
Just find the coordinate at the point where the x-coordinate is 3
Step-by-step explanation:
F(x) is just another term for Y. The variable of X is the value that you input into the f(x), which just stands for a function. Since the value that they asked for was 3, you know that they inputted the value of 3 as x. Just look where the coordinate at the point where the x-coordinate is 3 to find the answer.
Answer:
Sample Response: For f(3), the input is 3 and you are looking for the output. To determine the function's value when x = 3, go to the value of 3 on the x-axis and then locate the graph for that value of x. Determine the value of y from the y-axis at that location on the graph.

(I posted this same question like 4 times lol)
PLEASE ANSWER!!!!
Answer:
1. variable by itself with a coefficient of 1 on one side of the equation and all the other variables and constants on the other side.
2.Because solving an equation is to find its solutions, which are the values (numbers, functions, sets, etc.) that fulfill the condition stated by the equation, consisting generally of two expressions related by an equals sign. When seeking a solution, one or more variables are designated as unknowns.
