A train travels at 110 miles per hour. At this rate, how far will the train travel in 2 1/2 hours?110/1 (fraction) x 2 1/2 (mix number)

275 mi

Step-by-step explanation:

110 mi/hr × 2½ hr

Convert the mixed number to an improper fraction.

110 mi/hr × ⁵/₂ hr

Multiply the numbers.

⁵⁵⁰/₂ mi

275 mi

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
