<span>b/a=c/d
Two lines are parallel to each other if they have the same slope. So let's look at the options and see which one matches that statement.
b/aâ‹…c/d=â’1
* This is checking to see if the two lines are perpendicular to each other. Almost the exact opposite of parallel. So this is the wrong answer.
b/a=c/d
* b/a is a legitimate slope. c/d is also a good slope. And they're being checked to see if they're equal to each other. So this is the correct answer. But let's see if the next two options will give us a chuckle or two.
b/a=d/c
* b/a is OK. d/c almost looks ok, check the figure. And d/c is NOT a slope. The slope is delta Y over delta X. And d/c is delta X over delta Y. The inverse of the slope. So comparing those two values is meaningless. So it's a wrong answer.
b/aâ‹…d/c=â’1
* And they're trying the inverse of the slope trick again. WRONG. And they're checking if it's perpendicular. Also wrong. So definitely not a good choice.</span>
18 x 3 = 54. So the correct answer is D. 54 pounds.
Answer:
33%
Step-by-step explanation:
So you Subtract 20.8 by 15.6 and you get 5.2.
Then you divide 5.2 by 15.6 getting you .33. Then you'll make it into a percentage getting you 33%. This could be wrong but let me know.
I hope this helps! ^^
Answer:
The total area between the squares is of 24 units squared.
Step-by-step explanation:
Area of a square:
The area of a square of side length l is given by:

Area between figures:
The area between two figures is the area of the larger figure subtracted by the area of the smaller figure.
Larger square:
Square with side of length 7. So

Smaller square:
Square with side of length 5. So

What is the total area between the squares?

The total area between the squares is of 24 units squared.
1/5(25-5a)=4-a
⇔5-a=4-a
