5(R + 2) - 6....distribute the 5 thru the parenthesis
5R + 10 - 6 =
5R + 4 <==
Use the Pythagorean Theorem: a^2 + b^2 = c^2
a and b are the measures of the legs and c is the measure of the hypotenuse
Let's solve for a (the length of the other leg)
<em>*I am hoping that m is not a variable and just an abbreviation for meters* </em>
b = 4 m
c = 6 m
a^2 + 4^2 = 6^2
a^2 + 16 = 36
a^2 = 20
a =

Answer:
After 3 bracelets , the money taken in and the number of bracelets sold will be the same for the girls
Step-by-step explanation:
Let the number of bracelets that makes the amount of profit made be equal be x
For Sandy, her gain will be 10x - 25
For Selena, her gain will be 26x - 73
So equating both, we can find x
10x - 25 = 26x - 73
26x-10x = 73-25
16x = 48
x = 48/16
x = 3
To get the amount, we can make a substitution for x
we have;
10(3) - 25 = 30-25 = $5
