Answer:
Inequality : 4x+8 < 120
x<28
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a rectangle (P)= 2 length +2 width
Where:
Width = x
Length = x+4
Replacing with the values given
P = 2 (x+4) + 2x
P = 2x+8+2x
P=4x+8
Since the perimeter of the rectangle must be less than 120:
4x+8 < 120
Solving for x
4x<120-8
4x<112
x<112/4
x<28

Answer:
110
Step-by-step explanation:
Let x = rate #1 and then 155-x=rate #2.
15x + 5(155-x) = 1225
15x - 5x + 775 - 1225
10x = 450
x = 45, second rate is 110
We have 1.5 hours 30 minutes = 120 minutes;
1 hour 15 minutes = 75 minutes;
1.25 minutes = 85 minutes;
75 < 85 < 120
The median is 85 minutes.
Finally, 1 hour 15 minutes is the median.
Well, if it is based off the Pythagorean Theorem, here is the formula: a squared plus b squared equals c squared. It also works with c squared minus a squared equals b squared. I hope this helps! Please mark me brainliest!
