Let's deconstruct the equation.
K x (1/8) = 7
You want to isolate K, so you multiply by 8 for both sides (since 8 x 1/8 = 1)
So, K = 7 x 8
K=56
Y≤x/3-1 AND y≤x/3-3
So for BOTH inequalities to be true:
y≤x/3-3
Answer:
20
Step-by-step explanation:
16-12/4+3(6-2) subtract 6 and 2
16-12/4+3+4 divide 12 and 4
16-3+3+4 subtract 16 and 3
13+3+4 add all 3 numbers
13+7

24 foot board... I added a picture for the break down
7x^2 - 16x - 8 = 0
using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7
= (16 +/1 sqrt 480) / 14
= 2.71, -0.42 to nearest hundredth
