20/q = 7/9
20×9 = 7q
7q = 180
q = 180/7
Answer:
45 eggs left
Step-by-step explanation:
if they had 4 crates and each crate has 18, then we have a total of 72 eggs
subtract 27 eaten eggs from 72
72-27=45
they have 45 eggs left
7x-99=2x+1
5x=100
x=20
mark me brainliest if the answer is correct, thank you in advance :)
Answer:
So estimate.
Really depends on what needs to be estimated, the answer or the overall equation.
So doing the real one first.
283/11 = 25 8/11
You can’t have “part” of a student so rounding this you can go up since 8 is more then half of 11
So 26 students
If you were to round the overall equation then you’d get
280 / 10 which is 28 students per class
So two options.
Answer:
only 3.5 buy products made with recycled material but you have to round it to 4
