Answer:

The answer to your question is: first option

Step-by-step explanation:

                    \frac{2x}{3} - \frac{1}{2} = \frac{1}{3} + \frac{5x}{6}            

                  \frac{2x}{3} - \frac{5x}{6} = \frac{1}{3} + \frac{1}{2}

                                \frac{4x - 5x}{6} = \frac{2 + 3}{6}

                                       \frac{-1x}{6} = \frac{5}{6}

                                                             -x = 5

                                                              x = -5

What is the cofunction of cos 2pi/ 9
fiasKO [112]

The cofunction of cos is sin(90-x)

90 degrees is equal to PI/2

The cofunction becomes sin(PI/2 - 2PI/9)

Rewrite both fractions to have a common denominator:

PI/2 = 9PI/18

2PI/9 = 4PI/18

Now you have sin(9PI/18 - 4PI/18)

Simplify:

Sin(5PI/18)

The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops.
Lady_Fox [76]

Answer:

m(c(a)) = 4.8875a

Step-by-step explanation:

The missing parameters are:

c(a) = 4.25a --- Cost of marble countertops

m(c) = 1.15c --- Cost of retail markup

Required

The cost of marked up price

This implies that we calculate m(c(a))

We have:

c(a) = 4.25a

m(c) = 1.15c

m(c) = 1.15c can be written as:

m(c(a)) = 1.15*c(a)

Substitute: c(a) = 4.25a

m(c(a)) = 1.15*4.25a

m(c(a)) = 4.8875a

Hence, the cost of marked up price is: m(c(a)) = 4.8875a

Loren solved the equation 10 = StartFraction 19 Over 9 EndFraction (149) + b for b as part of her work to find the equation of a
Elden [556K]

The error that Loren made is C. She should have solved 149 = StartFraction 19 Over 9 EndFraction (10) + b for b.

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

It should be noted that an equation is a statement that shows that two mathematical expressions are equal.

In this case, for Loren to find the slope, this will be:

m = y2 - y1/x2 - x1

= (149 - 130)/(10 - 1)

= 19/9

In this case, the error that Loren made is that she should have solved 149 = StartFraction 19 Over 9 EndFraction (10) + b for b.
