We can use the distribution method for both sides:

9 (x+2) = 5 - 2( x - 1 )

9x + 18 = 5 -2x + 2

Move like terms to one side and combine:

9x + 2x = 5+2-18.

11x = -11

x = -1.

Match the amounts and tip or tax rates in the first column to the total costs in the second column.

gogolik [260]

Answer:

1. $132.24

2. $55.89

3. $1336.66

4. $258.19

5. $57.86

Step-by-step explanation:

Simply use this equation.

$\frac{InitialValue}{100} = \frac{x}{TaxPercentage}$

Substitute in our values, using No.1 as our example.

$\frac{123.01}{100} = \frac{x}{7.5}$

Cross multiply

922.575 = x100

Solve for x by dividing by 100.

x = 9.22575

Now add x to the initial value.

9.22575 + 123.01 = 132.23575

Round to the nearest hundredth for the answer.

$132.24

Find the distance between (8,8) and (3,1)

Vesnalui [34]

Answer:

About 8.6

Step-by-step explanation:

d=(x2-x1)^2+(y2-y1)^2

8=x1 8=y1 3=x2 1=y2

(3-8)^2+(1-8)^2

(-5)^2+(-7)^2

25+49

take the square root and you get about 8.6

Answer:

x ≈ 23.4

Step-by-step explanation:

You are correct that the given information indicates the tangent function is appropriate.

Tan = Opposite/Adjacent

tan(59°) = 39/x

Multiply this equation by x/tan(59°) and you get ...

x = 39/tan(59°)

x ≈ 39/1.6643 ≈ 23.43

The appropriate answer choice is ...

x = 23.4
