Answer:
11.2
Step-by-step explanation:
B is your answer because you have to get your formula from there u solve the question multiply 5.5 and 12.5 from there you divide and then you get your answer=11.2
Hope this helps:)
Pls mark brainlist
You have to find a common denominator. 12 is the easiest to get in this case. 5/4 * 3= 15/12, 1/3 * 4=4/12. 15/12-72/12+4/12. The answer is 53/12
1) The line will need to be vertical down the point of x, meaning draw a line down point x. Perpendicular lines look similar to t’s
2.) Same thing, just draw a line through point O and the line. They should look similar to t’s
Hope this helped!! I understand math can get really hard, soon it’ll all be over :)
7/9 = 42/54...when 42/54 reduces, it becomes 7/9...so this is proportional because proportions are nothing but equivalent fractions.
u could also check it this way...
12/21 = 15/24
cross multiply
(21)(15) = (12)(24)
315 = 288.....these do not equal and are therefore, not proportionate
440/4 = 300/3
110 = 100....not equal, so not proportionate
120/5 = 88/4
24 = 22.....not proportionate
66/82 = 99/123
0.804 = 0.804.......these are proportional
68/172 = 43/123
0.395 = 0.349......nope, not proportional
