What you want to do here is plug 2 in for x. when a question asks you to evaluate a certain equation at a certain number, it's just asking you to plug the value in for your variable. i'm assuming that 12x + 8 is meant to be set over 4 as a fraction.
(12(2) + 8)/4 ... figure out the top first. 12*2 = 24, 24 + 8 = 32.
32/4 = 8, so your correct choice is D.
240 = 100%
so 10% = 24 sandwiches
all - (tuna) - (jam) = egg
100% - 20% - 40% = 40%
40% = 10%*4
40% = 24*4 = 96
the answer is 96 egg salad sandwiches

Answer:
570
step-by-step explanation:
assuming you're talking about a 2-dimensional rectangle,
Area = base x height
base = 38
width = 15
Area = 38 * 15
Area = 570 ft
570ft * (1 yard/3ft) = 190 yards
