Answer:

Step-by-step explanation:
Given that,
...(1)
We need to find the value of
.
Put n = 1 to find the first term.

Put n = 2 to find the second term.

Put n = 3 to find the third term.

Put n = 10 to find the tenth term.

It means we need to find the sum of 5,7,9,.....,23.
The formula for the sum of n terms is given by :

We have, n = 10, a = 5 and 
So,

So, the value of
is equal to 280.
Answer:
Option 3x+5y=29 and -3x-12y=-48 is the system of equations equivalent to the given system of equations 3x+5y=29 and x+4y=16
Step-by-step explanation:
Given system of equations is 3x+5y=29 and x+4y=16
To find the equivalent system of equations to the given system of equations :
Option 3x+5y=29 and -3x-12y=-48 is the system of equations represents the given system of equations.
Because we can write the given equations as below
3x+5y=29 and x+4y=16
x+4y=16 rewritting as below
When multiply the above equation into (-3) we get

as same as the equation x+4y=16 so we can say that they are equivalent
Therefore Option 3x+5y=29 and -3x-12y=-48 is the system of equations represents the given system of equations
Therefore 3x+5y=29 and -3x-12y=-48 is the system of equations equivalent to the given system of equations 3x+5y=29 and x+4y=16
Answer:-4.03
Step-by-step explanation:
Because If the negative is farther away from zero it's less so 4.03 is greater because it's closer to zero
.7 and 7 are related because:
-If you move the decimal point left or right depending, they are the same number.
-They both stand for a value.
-They are both rational. They can both be put into a ratio or fraction.
I hope this helps!
