Solve the following equation using the distributive property.

Mathematics
1 answer:
svetoff [14.1K]3 years ago
5 0

Step-by-step explanation:

41.4 = 3.6(x + 4.5)

=> 41.4 = 3.6x + 3.6(4.5)

=> 41.4 = 3.6x + 16.2

=> 3.6x = 41.4 - 16.2 = 25.2

=> x =  \frac{25.2}{3.6}  = 7

Bottle A contains 4 ounces of water, which is 25% of the amount of water in Bottle B. How much water is there in Bottle B?
sveticcg [70]

Answer:

B=16 ounces

C=24 ounces

B=1/0.75=133%

Step-by-step explanation:

we have that

A≡0.25B (25%), if A=4 ounces  then B=4/0.25 = 16 ounces

C=1.5B (150%), if B=16 ounces then C=1.5*(16 ounces) = 24 ounces

D≡xB (?%), if D=12 ounces then x=12/16 = 0.75 ≡ 75%, but xB≡D ⇒ B≡D/x →

B≡12(1/0.75)= B=12*(1.333)→ B≅133%D

Begin by factoring 2 out of   2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0.  2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2.  The equation is true for these two x-values.

Carla is going to draw a marble from the bag shown below, replace it, and then draw another marble. What is the probability that
Contact [7]

Answer:

7/80

Step-by-step explanation:

(3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles

P ( green or yellow  ) = number of green or yellow / total

                = (3+4)/20  = 7/20

Replace  

so we have (3 green, 4 yellow, 5 blue, 8 pink) = 20 marbles

P (blue) = number of blue/ total

                = 5/20  = 1/4

P ( green or yellow, replace, blue) = 7/20 * 1/4 = 7/80
