Answer:
x=12
Step-by-step explanation:
twenty less = -20
from 8(times a number) and the number is unknown which means it would have variable next to the eight = 8x
therefore the equation would look like 8x-20 =76. then solve it like:
8x-20+20=76+20
8x = 96
8x/8=96/8
x= 12
Answer:
<h2>You will ride for 4 hrs 8min</h2>
Step-by-step explanation:
What we are expected to solve for that the problem did not expressly state is most likely the number of hours that you could ride for an amount of $65.
firstly we need to model the inequality (equation) for this scenario.
the constant fee= $3 additional fee for helmet
We can now solve for n since the above inequality satisfies the condition presented in the problem statement.

Divide both sides by 15 to find n

Answer:
221 mm
Step-by-step explanation:
The dimension 74 mm is presumed to mean that the actual length could be anywhere in the interval [73.5, 74.5). So, the minimum perimeter is ...
3 × 73.5 = 220.5 ≈ 221 . . . millimeters
_____
The perimeter of an equilateral triangle is 3 times the side length, since all three sides of the triangle are the same length.
