Answer:

Therefore the Final Solution is  x = 2 and y = 7  

i.e (2 ,7)

Step-by-step explanation:

Given:

-2x+y=3                ...............Equation ( 1 )

-3x+y=1                 ...............Equation ( 2 )

y=3x+1                   ..............Equation ( 3 )

To Find:

x = ?

y = ?

Solution:

Substituting Equation  ( 3 ) in Equation ( 1) we get

-2x+3x+1=3\\\\x=3-1\\\\\therefore x =2

Now Substituting x = 2 in Equation ( 3 ) we get

y=3\times 2+1=6+1\\\\\therefore y=7

Therefore the Final Solution is  x = 2 and y = 7  

i.e (2 ,7)

If avogadro's number of pennies is divided equally among the 250. million men, women, and children in the united states, how man
Anastasy [175]

We divide the pennies 100 to convert pennies to dollar

1 pennies= 1/100 dollar

Then we will convert 6.02×10∧23 p to dollar

=1 dollar/100 pennie ×6.02×10∧23

= 6.02×10∧21

The total men and women and children in 250 m  

=25×108

6.02×10∧21/2.5×10∧8

= 2.408×10∧13

I need help ASAP<br> Is 3, 4, 6, 9, 13, 18,… an arithmetic sequence? Why or why not
kirza4 [7]

Answer:

No

Step-by-step explanation:

No, this is not an arithmetic sequence because it goes up by a different number each time.

An example of an arithmetic sequence would be,

3, 5, 7, 9...

because it increases by 2 each time.

A geometric sequence is multiplied or divided by a set number each time.

An example would be,

2, 4, 8, 16...

because it is multiplied by 2 each time.

What is the greatest possible error when measuring to the nearest quarter of an inch
cestrela7 [59]
Using a scale that has increments that are somewhat large, you could get an error if you reach half of the measuring unit. This is because when you arrive at a measurement greater than half of the measuring unit, you would have to round it up. Therefore, the greatest possible error when measuring to the nearest quarter of an inch is 1/8 inch.                                                                The greatest possible error when measuring to the nearest quarter of an inch is how the reader reads the measurement. Sometimes, we base our answers to what we can see and what we see may be different from others.
