Describe the error found in m<1

The sum of all angles should be 180°

Step-by-step explanation:

Sum of all angles in a triangle = 180°

115° + 39° = 154°

180° - 154° = 26°

The student found 206°, lets add 206° to 154° and see what we get.

206° + 154° = 360°

Prediction : The student may have forgotten that the sum of all angles in a triangle equals 180° and not 360°

The sum of all angles should be 180°

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
