Answer:
x<5
Step-by-step explanation:
the greater sign will firstly be changed to = for better solving so we obtain
3+9x=4(x+7)by opening bracket
3+9x=4x+28
9x-4x=28-3
5x=25
divide all through by 5x
we obtain
x=5
the greater sign change here
which is x<5
Answer:
I believe it would be 7.5 miles in one hour.
Step-by-step explanation:
Write the problem out as a proportion. Divide 60 by 24. This is 2.5, so you then multiply the 3 miles by 2.5. There's your answer! :)
24 Minutes 60 Minutes
------------------- = ------------------
3 Miles (x2.5) 7.5 Miles
Answer:
B) x ≤ 0
Step-by-step explanation:
To figure this out, we must solve the inequality for x!
Right off the bat I can tell you it will not be A as we need a ≤ or ≥ and A has a < :D
Given:
2 (x + 12) - 16 ≤ 8
Disribute the 2:
2x + 24 - 16 ≤ 8
Combine like terms:
2x + 8 ≤ 8
Subtract 8 from both sides:
2x ≤ 0
Divide both sides by 2:
x ≤ 0
