Answer:
4120 feets
Step-by-step explanation:
Given that:
Starting elevation = 0 feets
Elevation gained on first day = 2150 feets
Total elevation at the end of day 1 = 0 + 2150 = 2150 feets
Elevation gained on second day = 1970 feets
Total elevation at the end of day 2 = 2150 + 1970 = 4120 feets
Elevation at the end of 3 rd day = 0 feets
Hence, elevation lost on day 3 ;
(4120 - 0) = 4120 feets
Answer:
well you would need to look at how much he gets a weekend, and then worry anout the tips.
Step-by-step explanation:
He gets paid $80 each weekend, and a 15% with tips.
you would need to figure out the tips, by taking the $725 and timesing it by .15 for the percent.
which would be 108.75
you would now take 108.75 and add 80 to get what he made that weekend.
108.75+80 = 188.75 dollars
Answer:
-5n + 20
Step-by-step explanation:
n stands for the term number so if you want to find the 50th term all you have to do is substitute n with 50
first of all find the difference between each number in the sequence
the difference between 25 and 20 is -5
the difference between 20 and 15 is -5
the difference between 15 and 10 is -5
the difference between 10 and 5 is minis -5
because
25-5=20
20-5=15
15-5=10
10-5=5
now that you know the the difference you place the number in front of n like this
-5n
to find the rest all you need to do is use the difference between each number which is -5 and do it on the first number
so 25 - 5
this gives 20
so our nth term is -5n + 20
if you still don't get i can re-explain it to you
x=smaller number
y=larger number
x+y=12
y=3x-6
Let's begin with the first equation...
x+y=12
Let's substitute...
x+(3x-6)=12
4x-6=12
Let's add 6 to both sides as we proceed to isolate x...
6+4x-6=12+6
4x=18
Let's divide both sides by 4...
(4x)/4=18/4
x=9/2=4.5---smaller number
12-4.5=7.5s larger number
9514 1404 393
Answer:
x = 19
Step-by-step explanation:
The two marked angles are corresponding angles, so have the same measure.
6x -9 = 5x +10
x = 19 . . . . . . . . . add 9-5x
