Answer:
A-75 and B-25
Step-by-step explanation:
Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section. Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.
If you convert all of the fractions to decimals.......
2/8=,25 1/8=.125 2/4=.5 2/6=.333333
So in this case 2/4 has the greatest value....
Answer:
I went shopping once for ingredients of a cake, but i didn't know what my finale price would be. So i estimated what the total cost could be, then i took all the prices and added them up then divided the price by how many ingredients i got to find the average and it was pretty close to my estimate. So math can help when you go shopping. (Sorry if how i find my prices is weird, i kinda just stand in one spot for at least 5 - 8 mins trying to find my price)

Answer:
a> -32
Step-by-step explanation:
-40 < 2(a +12)
-40 < 2(a) +2(12) <em>(</em><em>expand</em><em>)</em>
-40 < 2a +24
-40 -24 < 2a <em>(</em><em>bring</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>)</em>
-64 < 2a <em>(</em><em>simplify</em><em>)</em>
2a > -64
a > -64 ÷2
a > -32
