The mean is 52 because 42+45+58+63=208 then you divide it by the amount of numbers: 4 : 208 divided by 4= 52
308 + 397 + 389 + 286 = 1380
He drove 1380 miles
Answer:
3 / 4 * 50 = 150 / 4
= 37.5 or 37½ yards
Step-by-step explanation:
A rational number is any number that can be expressed as a ratio of two integers (hence the name "rational"). For example, 1.5 is rational since it can be written as 3/2, 6/4, 9/6 or another fraction or two integers. Pi (π) is irrational since it cannot be written as a fraction.
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
