The real engine is 65.25 feet long
<h3>How to determine the length?</h3>
The scale is given as:
Scale = 87 feet to 1 foot
The scale length is given as
Scale length = 9 inches
Convert inches to feet
Scale length = 9/12 feet
The actual length is then calculated as:
Actual = 87 * 9/12 feet
Evaluate
Actual = 65.25 feet
Hence, the real engine is 65.25 feet long

Answer:
- They will be on the same page after 6.5 days or
days.
- They will be on page 180.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
You know that Nora plans to read 8 pages per day until the next club meeting and she is on page 128.
With this information you can write the following equation of the line in Slope-Intercept form to represent the number of the page "y" she will be on after "x" days:

Know that Lila is on page 102 and plans to read 12 pages per day until the next club meeting, you can write this linear equation that represent the number of the page "y" she will be on after "x" days:

Since they will be on the same page after "x" days, make both equations equal and solve for "x":

Substitute that value into any original equation the same page they will be on after 6.5 days (or
days):

Answer:
10, 20, 40
Step-by-step explanation:
To know which point achieve min of 2x+2y, we need to test these four points:
0,7
2*0+2*7=14
3,7
2*3+2*7=6+14=20
6,3
2*6+2*3=12+6=18
6,0
2*6+2*0=12
so the point (6,0) is the point that satisfies the minimum value of 2x+2y
