Answer:
a = 19
Step-by-step explanation:
a+5/3 (Note: this means a+5 over 3, as in a fraction.)
3 x 8 = a + 5
24 = a + 5
24 + (-5) = (a + 5) + (-5)
19 = (a + 5) - 5
19 = a + 5 - 5
19 = a
a = 19

2/3(120) = 240/3 = 80 do not drink
4/5(120) = 480/5 = 96 do not smoke
72 do not smoke or drink
96 - 72 = 24 do not smoke
80 - 72 = 8 do not drink
72 do not do either
120 - (24 + 8 + 72) = 120 - 104 = 16 drink and smoke
Answer:
Step-by-step explanation:
Polynomials are factored after they are set equal to 0. This i because the factors of the polynomial are also known as the x-intercepts, and x-intercepts exist where y = 0. Therefore, if the factors of the polynomial are
(x + 8)(x + 4) = 0, then by the Zero Product Property,
x + 8 = 0 so x = -8 or
x + 4 = 0 so x = -4. Choice A.
