Answer: JK=

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.

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

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

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

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.

mike's final position relative to the ground is 3 feet's underground

Step-by-step explanation:

We take positive value when he is above the ground and then take negative value when he is below or underground

6 feet's underground = -6

He climbs up 14 feet = +14

He climbs down 11 feet = -11

We are required to find his last position relative to ground level

= -6+14-11

= (-6) + (-11) + 14

= -17 + 14

= -3

So we have it that mike's final position relative to the ground is 3 feet's underground

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.

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.

149

Hope this helps :)

The required value of the given expression at z = 7 and w = 10 is given as 179.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
z = 7 and w = 10

Now put these values in the given expression,
= 7z + 10w

= 7 × 7 + 10 × 10
= 49 + 100
= 149
