-4.5=-0.5(x-7.1) solve for x\

-0.5(x-7.1=-4.5

-0.5(x-7.1)
-----------------------------------
-0.5=   -4.5
------    -------
 -0.5    0.5


x=-7.1 + -4.5
              -----
              0.5    

expand : 4.5
              ----  = 9
              0.5 

x-7.1=9

add 7.1 to both sides

x-7.1+7.1=9+7.1

x+16.1

A certain roller coaster can accommodate 1600 riders per hour a digital sign states that there are 345 people in line if you get
sergiy2304 [10]
Given that the <span>roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

Given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

Therefore, it will take you 12.94 minutes to get to the front of the line.

Evaluate The quantity of x cubed plus 3x squared minus 2x plus 7 divided by the quantity of x minus 2 end quantity period.
Minchanka [31]

The value of x^3 + 3x^2 - 2x + 7 divided by x- 2 is (x^2 + 5x + 8) + 23/(x - 2)

<h3>What is a quotient?</h3>

Quotients involve the result of dividing a dividend by a divisor.

In other words, quotient means division or the result of a division operation

<h3>How to solve the quotient?</h3>

The quotient expression is given as:

(x^3 + 3x^2 - 2x + 7)/x- 2

Expand the numerator in the above expression

(x^3 + 5x^2 - 2x^2 + 8x - 10x - 16 + 23)/(x - 2)

Rearrange the terms of the numerator in the above expression

(x^3 + 5x^2 + 8x - 2x^2 - 10x - 16 + 23)/(x- 2)

Factorize the numerator in the above expression

[x(x^2 + 5x + 8) - 2(x^2 + 5x + 8) + 23]/(x - 2)


Factor out x^2 + 5x + 8

[(x -2)(x^2 + 5x + 8) + 23]/(x - 2)

Split the fractions

(x -2)(x^2 + 5x + 8)/(x - 2) + 23/(x - 2)

Divide the common factors

(x^2 + 5x + 8) + 23/(x - 2)

Hence, the value of x^3 + 3x^2 - 2x + 7 divided by x- 2 is (x^2 + 5x + 8) + 23/(x - 2)

Let the price of jeans at store b be $x.

Let the price of jeans at store a be $7x/8.

But the price of jeans at store a is $35.

Hence 7x/8 = 35

And therefore x = 40
