Answer:
18r
Step-by-step explanation:
since they both have r as their variable, they're like terms, meaning you can combine them
so 13+5 = 18
The bus fare is x, and the ferry fare is y.
x + y = 8
The bus fare will increase by 10% and the ferry fare will increase by 25%.
1.1x + 1.25y = 9.25
Multiply the first equation by -1.1:
-1.1x - 1.1y = -8.8
Add this to the original second equation.
0.15y = 0.45
y = 3
x + y = 8
x + 3 = 8
x = 5
The bus fare is $5, and ferry fare is $3.
We need to convert given value 465^8 as the base 5 number.
Let us assume x is the exponent of 5 when we take base 5.
We can setup an equation now.
5^x=465^8
Taking ln on both sides, we get
On simplifying, we get
Therefore, 
.
The formula of a distance between two points:
We have the points (0, 0) and (6, -8). Substitute:
If you follow PEMDAS, multiplication would be first, so 3*2 is 6, then it's addition.
So 3*2=6 and 8*-16 is -128, then you add them both.
So 6+(-128) is equals to -122. YOU'RE WELCOME :D
