Divide number of guitars by 100% and multiply into discount given



149/100 x 29

1.49 x 29

43.21



$43.21 had been removed

Therefore $105.79 is the guitar cost after discount

Solution of this equation
lara31 [8.8K]
2.5y + 3x = 27
5x - 2.5y = 5

Align the variables to make solving this easier.

2.5y + 3x = 27
-2.5y + 5x = 5

You can see that the 2.5y and -2.5y cancel each other out. Then add the 3x and 5x, and 27 + 5.

3x = 27
5x = 5

8x = 32

Divide both sides by 8.

x = 4

Now input that x into one of the equations to get y. 

2.5y + 3(4) = 27
2.5y + 12 = 27
2.5y = 15
y = 6

The answer to this system of equations is x = 4, y = 6. (4, 6)

Complete the table of inputs and outputs for the given function. F(x)= -5(x+7)
levacccp [35]

The table of inputs that satisfy the given function is (<em>-2, 25), (-1, -30), (0, 35), (1, -40) and (2, -45).</em>

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the function f(x) = -5(x + 7)

When x = -2; f(-2) = -5(-2 + 7) = -25

When x = -1; f(-1) = -5(-1 + 7) = -30

When x = 0; f(0) = -5(0 + 7) = -35

When x = 1; f(1) = -5(1 + 7) = -40

When x = 2; f(2) = -5(2 + 7) = -45

The table of inputs that satisfy the given function is (<em>-2, 25), (-1, -30), (0, 35), (1, -40) and (2, -45).</em>

Please, I beg you.

We know that the true value for pi is given as 3.14156.

Now, we have been given that the approximate value for pi is 3.141

We know the formula

Absolute error,  \Delta x = | \text{True value } - \text{ Approximate value} | \\&#10;\\&#10;\Delta x =|3.14156-3.141|\\&#10;\\&#10;\Delta x =0.00056

Relative error is given by

\text{Relative error }= \frac{\Delta x}{\text{true value} }\\&#10;\\&#10;\text{Relative error }=\frac{0.00056}{3.14156} \\&#10;\\&#10;[tex]\text{Relative error }=0.000178

The percentage error is given by

\text{Relative error } \times 100\\  &#10;\\  &#10;0.000178\times 100  &#10;\\  &#10;=0.0178 \%
