Answer:

x = -1

Step-by-step explanation:

3x - 5 = - 8 (6 + 5x)

3x - 5 = - 48 - 40x

3x + 40x = - 48 + 5

43x = - 43

x = - 43/43

x = - 1

Can you guys help me?
denis-greek [22]
Pretty sure you have to use the Pythagorean Theorem.
a^2+b^2=c^2

So you would plug in your numbers that you already have (6 and 10) But notice that 10 is the hypotenuse (longest side) so
6^2+x=10^2

Then you would solve it and you should end up with 11.6619

Natalija [7]

Fraction left after spending = 1 - 1/3 = 2/3

Fraction shared with 3 people = 5/12 ÷ 3 = 5/12 x 1/3 = 5/36
