The range of Ervin's scores is 55.
Range is the difference between the largest number and the smallest number.
To find the range of a set of values, first sort the values numerically (smallest to largest). With this set, it would look like this: 138, 142, 155, 165, 172, 193. Lastly, subtract 138 from 193 to find the range. By doing so, you will get 55 as an answer.
I hope this helps!
Answer:
Kayla and Maddy will be in the same level in 4 days.
Step-by-step explanation:
Kayla: y = 6x + 12
Maddy: y = 2x + 28
6x + 12 = 2x + 28
Subtract 2x from both sides;
4x + 12 = 28
Subtract 12 from both sides;
4x = 16
Divide both sides by 4;
x = 4
