Answer:

She estimated by rounding 245 to nearest tens and rounding 222 to nearest five.

Step-by-step explanation:

Given,

The miles she drove last week = 245

Since, 245 ≈ 250   ( because the ones place digit is 5 that is we will round up )

Also, the miles she drove this week = 222,

∵ The nearest 5 of 222 is 225,

Thus, the total miles she drove = 245 + 222 ≈ 250 + 225 = 475 miles

3) The length of JM is 9x + 6 units, the length of JK is
Vlada [557]

Answer:

JM = 60 units

Step-by-step explanation:

Given:

JM = 9x + 6

JK = 5x

KM = 3x + 12

JK + KM = JM (segment addition postulate)

(5x) + (3x + 12) = (9x + 6) (substitution)

Solve for x

5x + 3x + 12 = 9x + 6

Collect like terms

5x + 3x - 9x = -12 + 6

-x = -6

Divide both sides by -1

x = 6

JM = 9x + 6

Plug in the value of x

JM = 9(6) + 6

JM = 54 + 6

JM = 60 units

insens350 [35]

Answer:

The answer is 600 minutes (10 hours)

Step-by-step explanation:

20 minutes = 1 student.

30 students x 20 = 600 minutes

600mins / 60 (because an hour has 60 mins) = 10 hours.
