5*( -3.4k ) + 5*( - 7 ) + 3k + 12 = - 17k + 3k - 35 + 12 = -14k - 23 ;
Answer:
Step-by-step explanation
You must find the common denominator for all of them.
A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.
B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.
C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.
D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.
You earn $15 per lawn. 1 lawn would be $15. 15(1) is 15.
7 lawns would be 15(7), which is 105.
