official do you really expect me to complete your'e question,its even a sc question.

anyway if any of you want to skip the question above i got one for you.


simon pays 30c tax for every $1 he earns above $5000.if he earns $26,250 how much tax will he pay?

the answer is $6375,i just need to know how to solve problems like these,so please include working out and an explanation.(If you throw in a history question ill be more than happy to answer.)

lol? The above question is a simple co-ordinate Geom question which will be tested in the School Certificate. Don't get cocky and tell others to skip a completely legitimate question based on the fact that you can't do it.

terry goes to by a drink

500ml costs 75c

750ml costs $1

1 litre costs $1.50

which is the best buy?

750mL for $1

Find x:

2(x+4) + 3(x-1) = 15

 

[Amogh]

Find x:
2(x+4) + 3(x-1) = 15

2x+8+3x-3=15
5x+5=15
5(x+1)=15
so x=2

Question:
What is the name given to the change in speed and/or direction of an object?

750mL for $1

Find x:

2(x+4) + 3(x-1) = 15

2x+8+3x-3 = 15
2x+3x = 15+3-8
5x = 10
x = 2

Finding the unit costs we get:
a is 7c
b is 7.5c
c is same as a
so a/c is the answer

Hate to burst your bubble but b is $133.33 repeated per 1L, which is cheaper than both other options.

[Official]

Velocity.

Question:
Name the acid represented by the formula, HCl

Hydrochloric Acid. Isn't change in speed with reference to direction acceleration?

 

[Amogh]

Velocity.

Question:

Edit: @ Amogh: Yeh haha, =p

+3,i think

 

[Official]

chemical reactions

acid+metal=

acid+base=

acid+carbonate=

Acid + Metal = Salt + Hydrogen

Acid + Base = Salt + Water

Acid + Carbonate = Salt + Carbon Dioxide + Water
