Whatever% of anything is just (whatever/100) * anything.
so 56% of 75 mates like it, how much is 56% of 75? well is just (56/100) * 75, namely 42.
and 80% of 60 relatives like it as well, how much is 80% of 60? well, is just (80/100) * 60, namely 48.
how many more? well, 48 - 42.
It would be 30 square feet
54-10 ≥ 20+7x
44 ≥ 20 + 7x
44-20 ≥ 20-20 + 7x
24 ≥ 7x
24/7 ≥ 7x/7
3 3/7 ≥ x
30*sin(25°)
The answer is 12.68
Lila's error was that she added -7.13 to 63.97 to get -71.1
Lila steps are as folows
(−7.13 + 63.97) + (−54.8 − 3.4) = −71.1 + (−58.2) = −129.3
In the first bracket, Lila was suppose to subtract 7.31 from 63.97 since there is a negative in front of 7.31.
So, the correct expression should be
(−7.13 + 63.97) + (−54.8 − 3.4) = 56.84 + (−58.2) = 56.84 - 58.2 = −1.36
So, Lila's error was that she added -7.13 to 63.97 to get -71.1
