Step By Step Solution:
(See image above)
Answer:
total distance= 12000+12000=24000
total time = 5+6=11
average speed of plane= 24000/11
5(7x - 15) + 2x ≥ 13x - 3 <em>multiplied both sides by 2 to clear the denominator</em>
35x - 75 + 2x ≥ 13 x - 3 <em>distributed 5 into 7x-15</em>
37x - 75 ≥ 13x - 3 <em>added like terms (35x and 2x)</em>
24x - 75 ≥ -3 <em>subtracted 13x from both sides</em>
24x ≥ 72 <em>added 75 to both sides</em>
x ≥ 3 <em>divided both sides by 24</em>
Answer: x ≥ 3 Notation: [3, ∞)
1.8 divided by 7.74 is 0.23 .
And 56.4 divided 4.7 is 12 .
To find the percent decrease you do
final/initial
360/450 = .80
Then you find the gap between 1 which would correspond to 100 percent
.8 + x = 1
x = .2
there was a 20 percent decrease in sales
