Answer:
2.50(10) + 3x = 135.97, x = 38.66
Step-by-step explanation:
This should be pretty simple.
Basically, we know that he bought 10 pairs for 2.50 so that's $25 right there.
Our total is 135.97 though-
so here, we take our total from the right side of the equation, and subtract 25 from that.
135.97 - 25 = 115.97
Since he bought three pairs, divide it by 3.
115.97 / 3 = 38.66
One pair of shoes costs $38.66 - hope this helps!
143 seats
because 2920 seats/20 sections=143 seats in each section
We have no clue because you have not said what the speed/pace is. At a speed of 17.23 mph you will bike 112miles in 6.5 hours.
Answer:
choose "infinitely more solutions"
Step-by-step explanation:
Let's solve this system by substitution method
y+1=2x
- 1 = - 1
y = 2x -1 <-- sbstitute this in the next equation
---------------------------------------------------------------------------------
5y+5 = 10x
5(2x -1) + 5 = 10x
10x -5 + 5 = 10x
10x + 0= 10x
- 10x = -10x
0 = 0 <-- infinitely more solutions
