First what you need to do is make 6meters into centimetres so what how many meters in a centimetre
100cm so you do 100 x 6= 600
After that you do 600 divided by 28 then by 78 then you will find the answer.
Answers:
16. 6-x= 10
move +6 to the other side
sign changes from +6 to -6
6-6-x= 10-6
-x= 4
Mutiply both sides by -1
(-1)(-x)= (-1)(4)
x= -4
17. 4a+3= -9
move +3 to the other side
sign changes from +3 to -3
4a+3-3= -9-3
4a= -12
divide both sides by 4
4a/4= -12/4
a= -3
I think it is 3 A but it is hard to know what the question is asking... but my logic is that 3 A is right because A = 1+2 = 3
Well a half cup is 2/4 and if the serving size is 3/4 there is only 66.66% of the serving size needed hope this helps!
10*a = 10000000
a = 1000000, one million
5*10*b = 500000000
b = 10000000, ten million
About ten times.
