kherson [118]

Answer:

3 people

Step-by-step explanation:

If 20 people each bring 3 food dishes to an awards banquet, the total amount of food brought will be (20 * 3) = 60foods

If the dishes are shared equally by 180 people at the banquet, then;

60foods = 180 people

1 food = x

Cross multiply

60* x = 180

60x = 180

x =180/60

x = 3

Hence 3 people will share 1 dish

Mathematics algebra essay
Komok [63]

Answer:

The answer is D $3.35

Step-by-step explanation:

2.35 + .25x = 1.75 + .40x \\ 2.35 = 1.75 + .40x - .25x \\ 2.35 = 1.75 + .15x \\ 2.35 - 1.75 = .15x \\ .60 = .15x \\   \frac{.60}{.15}  = x \\ x = 4

2.35 + .25(4) = 2.35 + 1 = 3.35

Dmitrij [34]
K(x) = 5x-6
(k+k)(x) = k(x) + k(x) = 5x-6 +5x-6
just plug in x = 4,
(k+k)(4) = 5(4) -6 + 5(4) -6
thats your answer, the last option.
