shirley owns a diner. she decides to charge $1.50 for 2 egga and one piece of toast a $.90 for one egg and one piece of toast. w
charle [14.2K]

Answer:

1 toast costs $0.30 and 1 egg cost $0.60

Step-by-step explanation:

Let price of 1 egg be  e  and price of 1 toast be  t

<u>"$1.50 for 2 eggs and one piece of toast":</u>

We can write  2e+t=1.50

<u>"$.90 for one egg and one piece of toast":</u>

We can write  e+t=0.90

Now, we can solve the first equation for t and substitute that into 2nd equation and solve for e:

t=1.50-2e\\Also\\e+t=0.90\\Substituting:\\e+(1.50-2e)=0.90\\e+1.50-2e=0.90\\-e=0.90-1.50\\-e=-0.6\\e=0.6

Now using the value of e (0.6) and putting it back in the first equation, we will get t:

2e+t=1.50\\2(0.6)+t=1.50\\1.2+t=1.50\\t=1.50-1.20\\t=0.30

Hence, 1 toast costs $0.30 and 1 egg cost $0.60

84 is 60% of what number?
Fudgin [204]

To convert a percent to a decimal, you divide by 100.


60% = 0.60


If x is the unknown number, the word is means equal


84 = 0.60 * x


Divide both sides by 0.60


84/0.60 = (0.60/0.60)* x = x


140 = x

The greatest common factor of 6 and 34
lapo4ka [179]

Hey there. So if you divide 34 by 6 you get a decimal. So keep going down the line. Next number you could try is 3. Well that is a decimal too. So the next option would be 2. And that gives you answer of 2. Hope this helps:)
