(a)

pavan saves = x

his 1st brother saves = x + 4

2nd brother saves = x +4

all together they save = x + x +4 + x + 4

= 3x+8

so

3x + 8 = 26

(b)

3x + 8 = 26

subtract 8 from.both side

3x + 8 - 8 = 26 - 8

3x = 18

divide by 3 both side

3x/3 = 18/3

x = 6

so pavan saves $ 6 each month

There are two types of tickets sold at the Canadian Formula One Grand Prix race. The price of 4 grandstand tickets and 2 general
padilas [110]
Answer:
*a general admission ticket is $160
*a grandstand ticket is $390

Explanation: make 2 equations from the provided information
**g is a grandstand ticket and a is a general admission ticket.

4g+2a=1880, 4g+4a=2200
Steps: 4g+2a=1880 changes to 4g=1880-2a because you move the 2a in order to solve for g.
You can substitute the 4g into 4g+4a=2200 to get 1880-2a+4a=2200 and simplify to get 1880+2a=2200. subtract 1880 from both sides and you get 2a=320. divide both sides by 2 to get a=160.
After that you can substitute the value for a into 4g+4a=2200 to get 4g+4(160)=2200. simplify to get 4g+640=2200. subtract 640 from both sides to get 4g=1,560. divide both sides by 4 to get g=390.

Hope this helped! :)

How do you do the math of 8 divided by 624
Veronika [31]
We can write it down as a fraction:

\frac{8}{624}

and we can simplify this fraction:

\frac{8}{624} 
=\frac{4}{312}
=\frac{2}{156}
= \frac{1}{78}

or we can write it as a decimal:
0.1282...

A function f is given by the data in the table. I am currently working with Derivatives but i can’t solve this one.
mariarad [96]

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

One way to approximate the derivative at a point is by finding the slope of the secant line between points on either side. That is what is done in the attached spreadsheet.

  f'(0.1) ≈ (f(0.2) -f(0.0))/(0.2 -0.0) = -5 . . . for example

__

Another way to approximate the derivative is to write a polynomial function that goes through the points (all, or some subset around the point of interest), and use the derivative of that polynomial function.

These points are reasonably approximated by a cubic polynomial. The derivative of that polynomial at the points of interest is given in the table in the second attachment. (f1 is a rounding of the derivative function f')
