Writing the problem as an equation you have:
2x+6 > -16
Solve for x:
2x+6 > -16
Subtract 6 from each side:
2x > -22
Divide both sides by 2:
x > -11
The answer is: x > -11
Answer:
57.1428571429 miles per hour <em>Round off the answer to what your teacher asked.</em>
Step-by-step explanation:
Since we want final answer in miles per hour, lets change the 30 mins to 0.5 hours
Phase 1 =25miles per 0.5 hours
Phase 2 = (200miles-25miles) per 3 hours
Speed = distance/time
Average speed = total distance/ time
Total distance is 200miles because both phases say from new york that means it travels 25 miles away from new york then 3 hours later it is 200 miles away from new york
total time =3 hours+0.5 hours = 3.5 hours
Average speed = 200/3.5
Average speed = 57.1428571429 miles per hour

A cube represents 1,000 and a flat 100. You can solve this problem by saying the number out loud. "One thousand, two hundred." That means that you need one thousand (cube) and two hundreds (flat). So one cube and two flats will be 1,000+100+100, which equals 1,200.
Average is the sum divideided by the number of numbers added together
so avarage of 3 number is 15 means
three numbers represented as x+y+z so
= 15
(x+y+z)/3=15
multiply both sides by 3 to clear fraction
x+y+z=45
45 is the sum of the 3 numbesr
double of that is
45 times 2=90
