Answer:
The difference is 48 meters
Step-by-step explanation:
<u><em>The question is</em></u>
What is the difference of the hikers' altitudes?
Let
x -----> the Melissa's altitude in meters
y ----> Brian's altitude in meters
we have that
---> is positive because is above sea level
---> is negative because is below sea level
Remember that the sea level is the altitude equal to zero
<em>Find the difference</em>
To find out the difference of the hikers' altitudes, subtract Brian's altitude from Melissa's altitude
so
Remember that (-1)(-1)=+1
15-2x3=9 following the rule of PEMDAS
Answer:
<em>7, 22</em>
Step-by-step explanation:
Let S = the smaller number.
"The larger number is 1 more than 3 times the smaller number."
The larger number is 3S + 1.
The difference between the numbers is 15, so the larger number minus the smaller number equals 15.
3S + 1 - S = 15
2S + 1 = 15
2S = 14
S = 7
The smaller number is 7.
larger number = 3S + 1 = 3(7) + 1 = 21 + 1 = 22
The larger number is 22.
