Whats a good explanation for a bag contains 120 marbles. Some are red and the rest are black. There are 19 red marbles for every black marble. How many red marbles are in the bag?

114 marbles

Step-by-step explanation:

From the question, we are told that a bag contains red and black marbles which are 120 marbles in total. We are further told that there are 19 red marbles for every black marble.

Let the number of black marbles be represented by a.

The red marbles will be: = 19 × a = 19a

Based on the information given in the question,

Black marbles + Red marbles = 120

a + 19a = 120

20a = 120

a = 120/20

a = 6

Black marbles = 6

Red marbles = 19a = 19 × 6 = 114 marbles

answer: 12

step-by-step explanation:

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
