Answer is C) 6

36 + 3(4x - 9) = 6(2x + 1)

36 + 12x - 27 = 12x + 6

12x - 12x = 6 - 9

0 ≠ -3

A​ self-tanning lotion advertises that a 4 ​-oz bottle will provide seven applications. Jen found a great deal on a 13 ​-oz bott
Rainbow [258]

Answer:

22.75 applications

Step-by-step explanation:

From the above question, we understand that:

4 ​-oz bottle = 7 applications

13 ​-oz bottle = x applications

Cross Multiply

4 -oz bottle × x applications = 13 -oz bottle × 7 applications

x applications = 13 -oz bottle × 7 applications/4 -oz bottle

x applications = 22.75 applications

Therefore, the number of applications of the 13 -oz bottle​ self-tanner that should Jen​ expect is 22.75 applications.

Bruno is a manager at a factory that makes in-line skates. The
SashulF [63]

Answer:

Slope- intercept form   y = 200 x + 500

Step-by-step explanation:

Given that the equation

       200x - y + 500 = 0

where   y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours

The slope-intercept form

                y = m x +C

Given equation  200x - y + 500 = 0

                          200 x + 500 =y

                       y = 200 x + 500

Slope of the equation m = 200 and y-intercept 'C' = 500

If triangle RST is within Quadrant 4 and cos R= √3/2, what is the value of cotR
Nesterboy [21]

Answer:

CotR = -√3

Step-by-step explanation:

In the 4th quadrant, sin is negative;

Since Cos R = √3/2,

Adjacent = √3

Hypotenuse = 2

Get the opposite;

opp^2 = 2^2 -(√3)^2

opp^2 = 4 - 3

opp^2 = 1

Opp = 1

Get sinR

Sin R = opp/hyp

SinR=  -1/2

CotR = cosR/sinR

CostR = (√3/2)/(-1/2)

CotR = √3/2* -2/1

CotR = -√3

Solve for x:2/5 (x - 2) = 4x
Helen [10]

Answer:

x= -2/9

Step-by-step explanation:

2(x-2)/5=4x

2(x-2)=4x*5

2(x-2)=20x

x-2=20x/2

x-2=10x

-2=10x-x

9x= -2

x= -2/9
