Answer:
x=8
Step-by-step explanation:
Answer:
a) 15.28 hours
Step-by-step explanation:
535/-35
≈-15.28
but time is always positive so it would take him 15.28 hours
C is your answer. 5x + 2 = 17
First let’s get them all in terms of x:
Box kites = 3x
Dragon kites = x + 2
Butterfly kites = x
Adding all those up:
x + 3x + x + 2 = 17
Combine like terms:
5x + 2 = 17
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>
