it would be 79 because 7 tens is 70 and 9 ones is 9
Answer:15 nickels nd 5 quarters
Step-by-step explanation:
i hope this helps
Explanation:
The equation is 
Frida started to solve the equation by adding 3 to both sides.
Thus, the equation becomes,

This will not solve the equation.
To solve the equation
, we need to divide both sides of the equation by 3.
Thus, the equation becomes,

Dividing we get,

Hence, Frida cannot solve the equation by adding 3 to both sides of the equation. To solve the equation, Frida needs to divide both sides of the equation by 3.
Thus, to solve the equation
Frida needs to divide both sides of the equation by 3.
The infinite sequence of geometric terms is divergent if you try to add up all the terms. Sure the first 20 terms will add up to a fixed number but this isn't true for an infinite number of terms. The reason why the infinite series diverges is because r = 1.1 is larger than 1. If r > 1 then the infinite series diverges. It only converges if -1 < r < 1.
To write this in sigma notation, you would write

which is the result of adding the terms of 100(1.1)^(n-1) for n = 1 all the way up to n = 20. You can compute this by hand or preferably with a calculator or spreadsheet program
Answer:
v = - 1
Step-by-step explanation:
Collect like terms on the right side of the equation
3 = - 3v ( divide both sides by - 3 )
v =
= - 1
