For this we simply divide the total ft. by the ft. in a mile
Hmm iv never done ths quite before bt i think X=6 and the other X=40 how i got tht is a bit hard to explain...bt yah the best i got
Answer:
B and D
Step-by-step explanation:
This must be a six sided figure
A. 15 x 15. This would be area
B. 6 x 15. This is the sum of six sides of 15
C. 15 + 6. This is the sum of 2 sides of different length
D. 15 + 15 + 15 + 15 + 15 + 15. This is the sum of six sides of length 15
Multiply both sides by 8 (to undo the division of 8)
x/8 < 10
8(x/8) < 8*10
x < 80
So any number less than 80 will make the original inequality true. This applies to choices: C, D, E which are the final answers. These values are all less than 80.
---------------------------------
Alternatively we can plug in each value into the inequality to check them
Choice A
x/8 < 10
80/8 < 10
10 < 10
false; choice A is eliminated
-------
Choice B
x/8 < 10
96/8 < 10
12 < 10
false; choice B is eliminated
-------
Choice C
x/8 < 10
64/8 < 10
8 < 10
true; choice C is one of the answers
-------
Choice D
x/8 < 10
40/8 < 10
5 < 10
true; D is another one of the answers
-------
Choice E
x/8 < 10
32/8 < 10
4 < 10
true; choice E is another solution
-------
Choice F
x/8 < 10
88/8 < 10
11 < 10
false; choice F is eliminated
---------------------------------
Whichever method you end up using, the final answers are C, D, E
Answer:
Step-by-step explanation:
480 because you multipy 4 times 8 and than you mulpyy 48 times 10 and that is how i got the number 480.
