Your tip total will be $5.30 and your bill total will be $31.80 after tip.
Short leg = 18 Long leg= 24 Hypotenuse= 30
My calculations were simple trial and error. I started with a trial of 10 for the short leg to begin with, averaging and estimating the appropriate proportions based off 6 additional increments. Sorry I don't have an algebraic method for you. Hope this has helped somewhat :)
ANSWER

EXPLANATION
First equation:

Second equation:

Let us equate the two equations and solve for x.
This implies that;

Group similar terms to obtain:

Simplify:

Divide both sides by 3

Put x=-2 into any of the equations.
I will put x=-2 into the first equation:

This implies that,

Answer:
Fifteen is a factor of the number because both 3 and 5 are prime factors.
Step-by-step explanation:
2^3 * 3^2 * 5
= 2 * 2 * 2 * 3 * 3 * 5
As you can see from, the prime factors are 2, 3, and 5.
3 × 5 = 15, option A is correct.
assuming you means k = log_2(3) [as log(2)3 is the same thing as 3log(2) due to multiplication being commutative]
given log(ab) = log(a) + log(b)
log_2(48) = log_2(3) + log_2(16)
