Answer:
100 square inches
Step-by-step explanation:
Dimension of each of the ten pictures= 4 inches by 6 inches
Area of one of the pictures=4*6=24 Square Inch.
Total Area of the 10 pictures=24*10=240 Square Inches.
Dimension of the Poster Board=20 inches by 17 inches.
Area of the Poster Board=20*17=340 Square Inches.
Area not covered by the pictures=340-240=100 Square Inches
Therefore, 100 square inches of the green background will show after the pictures are mounted.
Since the equation is parallel to y=2x-4 that means they have the same slope. Now that you have the slope and fortunately a point, you can solve this by using point slope formula

Which is what I did on the attached picture and just rearrange it after solving to Ax+By=C/2x-y=6
The answer is 5a+15b-10
5 x a is 5a. 5 x 3b is 15b and 5 x -2 is -10.
You then put them together 5a+15b-10
Answer:
1 13/30
Step-by-step explanation:
First you want to make the denominators the same. You do this by multiplying them. However, whatever you do you to the denominator, you must also do to the numerator:
-
=
-
=
Now reduce to simplest terms:
=1
Answer: The original number was 18.25 or 18 1/4
