3(5y - 4) + 31 - 3y) = 3(2y - 3)<br> How to solve it

kumpel [21]

After solving $3(5y - 4) + 31 - 3y = 3(2y - 3)$ the value of y is $y=-\frac{14}{3}\,\,or\,\,y= -4.66$

Step-by-step explanation:

We need to solve the expression:

$3(5y - 4) + 31 - 3y = 3(2y - 3)$

and find the value of y

Solving:

$3(5y - 4) + 31 - 3y = 3(2y - 3)\\15y-12+31-3y=6y-9\\Combining\,\,like\,\,terms:\\15y-3y-6y=-9+12-31\\15y-9y=12-40\\6y=-28\\y=-\frac{28}{6}\\y=-\frac{14}{3}\\or\,\,y= -4.66$

So, after solving $3(5y - 4) + 31 - 3y = 3(2y - 3)$ the value of y is $y=-\frac{14}{3}\,\,or\,\,y= -4.66$

DerKrebs [107]

<h2><u>Ticket prices</u></h2>

According to the calculations made, the greater the number of tickets sold, the lower the variable amount to be paid for each ticket.

Since a band has been playing weekly at local venue, and they have been making a fixed amount, plus they receive additional money for every ticket sold, and last week they sold 40 tickets and were paid $ 200, while the week before that they sold 70 tickets and were paid $ 260, to determine the relationship between the number of tickets sold and the amount the band will be paid, the following calculation must be performed:

200/40 = X
5 = X
260/70 = X
3.71 = X

Therefore, the greater the number of tickets sold, the lower the variable amount to be paid for each ticket.

Plz help me and explain how you got your answer thx

mixas84 [53]

Answer:

The correct answer would be C = 533,800

Step-by-step explanation:

The formula for circumference is C = 2πr. To find the radius you must divide the diameter by 2.

Radius = 85000

now we have C = 2 * 85000 * 3.14

C = 533,800

<em>Scientific Formula = 5.338 x 10^6</em>

What is the slope of the line that passes through the points ( 10, 1) and

DiKsa [7]

Answer:

m(slope)=0

Step-by-step explanation:

To find slope given two points, use the formula m = y2 - y1/x2 - x1

(-10) - (-10)/(-3) - 5

0/-8

Anything being divided from 0, or divided by 0 is always 0, so the slope is 0.

Hope this helps.
