Aplant costs £6.80.julie has £30.00 how many plants can she buy?

Julie can buy 4 plants

Step-by-step explanation:

A plant costs £6.80 and Julie has £30.

In order to find out how many plants she can buy with £30, we need to see how much times £6.80 can go into £30. In other words, we need to divide £30 by £6.80 so we get the number times it can go into £30. That will be the number of plants.

£30 ÷ £6.80 = 4.41176470588

Julie can't get 0.41176470588 of a plant so we have to round it to 4. She can buy 4 plants.

She has a bit of money left over (you can tell by the decimal number), but that isn't enough to buy another plant. So she buys 4 and has £2.80 left.

£6.80 x 4 = £27.20

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.
