Answer:
L = 25
Step-by-step explanation:
Let's call the Length x and width x - 15 since the width is 15 less than length
Eric needs 70 of fencing in total, the perimeter of a rectangle is calculated by adding all sides
x + x + (x - 15) + (x - 15) = 70 add like terms
4x - 30 = 70 add 30 to both sides
4x = 100 divide both sides by 4
x = 25
In order to find this out, we just flip this equation to find the inverse solution.
180-147=?
33.
Answer:
input: x+4 output (x,y)
-2 -2 + 4 =2 2 (-2,2)
0 0 + 4 = 4 4 (0,4)
2 2 + 4 = 6 6 (2,6)
...
Step-by-step explanation:
continue by plugging in x to the equation, x is input and y is output
then just plot your (x,y) points on the graph.
We can assume that B leaves Los Angeles not at noon but at 2pm Eastern Time, so 5 hours later than A leaves New York.
In 5 hours A covers 5*40=200 miles. So, A and B together should cover 3,000-200=2,800 miles.
Combined rate = 40 + 60 = 100 miles per hour.
To cover 2,800 miles they'll need 2,800/100=28 hours.
2pm Eastern Time on Monday + 28 hours = 6pm Eastern Time on Tuesday.
Answer: 6:00pm on Tuesday
25 because you have to multiply 5✖️5 which equals 25. 5 is the 5 layers and the other 5 for the 5 rows.
