Answer:

x = 4

Step-by-step explanation:

to find the zero let f(x) = 0 , that is

- 2x + 8 = 0 ( subtract 8 from both sides )

- 2x = - 8 ( divide both sides by - 2 )

x = 4

Tony separates a number of paintbrushes, x, into 3 equally sized groups. He claims that this is the same as making a group 1/3 t
DochEvi [55]

Answer:

Size of each group = \frac{x}{3}

Step-by-step explanation:

Total number of paint brushes = x

Since each the three groups are equally sized, to get the number of paintbrushes in a group, we will have to divide the total number of paint brushes by 3

∴ We have, number of paint brushes in a group = \frac{Total number of paintbrushes}{3}\\

= \frac{x}{3}

this is also the same thing as saying \frac{1}{3}×\frac{x}{1}

This shows that the size of the new group is the same as \frac{1}{3} the size of the original group

Sara bought a 16-ounce jar of strawberry jam for $3.20 What is the unit price?
wolverine [178]

Answer:

$0.20

Step-by-step explanation:

so you have 16 ounces of jam. i personally like jelly, but that's besides the point lol

so for those 16 ounces, you paid $3.20 for them.

unit price is just a term for the price of 1 item or measurement. you can use this to find out what product you are purchasing has the better deal, because you always want more product, for less money.

you should take the amount of money you are spending, and divide it by how many total ounces it has.

$3.20 / 16 = 0.20

this means that 1 ounce of jam costs $0.20

you can check your work by multiplying the price of one ounce, by how many ounces the jar is.

.2 * 16 = 3.20

i hope this was helpful to you and i explained well enough!

stay safe!!
