To find this we should put this into an equation:
10x + 20 = 11x + 15
With x being number of months passed.
First, we subtract 15 from both sides to get:
10x + 5 = 11x
Then subtract 10x from both sides to get:
5 = x
So the costs will be the same after 5 months, hope this helps!
Yes because 18% is an abbysmal amount for a tip
Show that n is odd →∃m∈ℤ,n2=8m+1
Let k be an integer so that n=2k+1. Then n2=(2k+1)2=4k2+4k+1=2(2k2+2k)+1.
But this isn't equal to 8m+1, so can I change that into 4(2m)+1?
<span>Write
an algebraic expression for three fourths the square of b
=> Algebraic expression is the expression that shows both integers,
variables, symbols and operations like addition, subtraction, division, and
multiplication.
=> three fourth is a fraction which is equals to 3/4
=> square of b is an exponent which is equals to b<span>2
</span>=> thus, the algebraic expression of three fourths the square of b is
equals to:
=> ¾ x b2 or 3b2 / 4</span>
♥ Let's solve:
15n+5n can be known as 15+5.
15+5=20 now add n.
Final answer: 20n
