- HAM & CHEESE How much more doesthe ham and cheese omelet cost than the
cheese omelet?

Answers

Answer:

$1.40 more

Step-by-step explanation:

Let's say:

A costs $z

and

B costs $y

A is more expensive than B. That means z is greater than y. When we will be asked to find HOW MUCH MORE A costs than B, we will have to subtract the smaller dollar value (which is y) FROM the larger dollar value (which is z).

So, we would say A costs more than B by ($z - $y).

Similarly, in this problem, see attached image, the HAM AND CHEESE costs MORE ($4.95) than the CHEESE ONLY ($3.55). How much more??

To find this, we subtract smaller value (3.55) from the larger value (4.95). Thus we have:

$4.95-3.55=1.40$

Ham and cheese omelet costs $1.40 more than cheese omelet.

1/4(8−6x+12 ) what is the best expression

Answers

if you want us to simplify then

first simplify the parenthasees
8-6x+12
8+12-6x
20-6x

now we have
(1/4)(20-6x)
distribute using distributive porperty wyich says
a(b+c)=ab+ac

(1/4)(20-6x)=(20/4)+(-6x/4)=5-3/2x
