17, you only have to add up a few because of the x and y placements. Hope this helps you :)
Answer:
After 4 months
Step-by-step explanation:
The cost at both the programs consists of a "fixed cost" (reg fee) & "variable cost" ( per month fee).
Let number of months be "x"
<u>Yo-Yoga:</u>
35 fixed
90 per month
So equation would be: 35 + 90x
<u>Essence Yoga:</u>
75 fixed
80 per month
So equation would be: 75 + 80x
To find number of month when cost would be same, we equate both equations and solve for x:
35 + 90x = 75 + 80x
10x = 40
x = 40/10
x = 4
hence, after 4 months, both cost would be same
Answer:
8-(5-x)=2x-8 ⇒ common difference
Step-by-step explanation:
5-x,8,2x
to find the arithmetic difference of the progression
8-(5-x)=2x-8 ⇒ common difference
and solve for x
8-5+x=2x-8
3+x=2x-8
x=11
Answer:
(8x-9)(8x+9)
Step-by-step explanation:
64x^2 - 81
Rewriting
(8x)^2 - 9^2
We recognize that this is the difference of squares
a^2 - b^2 = (a-b)(a+b)
(8x-9)(8x+9)
