Answer:
Unit rate of oreos = 19.23 cents/oz
Unit rate of Chips Ahoy = 17.86 cents/oz
The cheapest and most affordable is the chips ahoy because it has a lower unit rate.
Step-by-step explanation:
Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ
We would be finding the Unit Rate of each product.
For Oreos
Oreos $2.98 for 15.5.Oz
We convert dollars to cents
1 dollars = 100 cents
2.98 dollars = x
x = 2.98 × 100 cents
= 298 cents
Hence, the unit rate in cents/oz
= 298 cents/15.5 oz
= 19.225806452 cents/oz
= 19.23 cents/oz
For Chips ahoy
$2.50 for 14.Oz
We convert dollars to cents
1 dollars = 100 cents
2.50 dollars = x
x = 2.50 × 100 cents
= 250 cents
Hence, the unit rate in cents/oz
= 250 cents/14 oz
= 17.857142857 cents/oz
= 17.86 cents/oz
Therefore, the cheapest and most affordable is the chips ahoy because it has a lower units rate.
Vertical angles are angles opposite each other where two lines cross
Multiply both sides of the second equation by 100 to get rid of the decimals:
0.05<em>n</em> + 0.10<em>d</em> = 1.50
==> 5<em>n</em> + 10<em>d</em> = 150
Multiply both sides of the first equation by -5:
<em>n</em> + <em>d</em> = 21
==> -5<em>n</em> - 5<em>d</em> = -105
Add the two equations together:
(5<em>n</em> + 10<em>d</em>) + (-5<em>n</em> - 5<em>d</em>) = 150 + (-105)
Notice that the terms containing <em>n</em> get eliminated and we can solve for <em>d</em> :
(5<em>n</em> - 5<em>n</em>) + (10<em>d</em> - 5<em>d</em>) = 150 - 105
5<em>d</em> = 45
<em>d</em> = 45/5 = 9
Plug this into either original equation to solve for <em>n</em>. Doing this with the first equation is easiest:
<em>n</em> + 9 = 21
<em>n</em> = 21 - 9 = 12
So Donna used 12 nickels and 9 dimes.
To find your answer you would find the perimeter of the small square which is 28.
You would then find the perimeter of the big square which is 56.
Next, you subtract 56 from 28 and get 28.
So the difference is 28 inches.
Hope this helps!!
So what you do is go 5(3y+5)-4y=14 which equals 15y+25-4y=14 which turns into 11y+25=14 than you move the 25 over which equals 11y=-11 so y=-1 then you enter -1 in for y which looks like 5x-4(-1)=14 than you solve that which is 5x+4=14 than you move the 4 over and you get 5x=10 than x=2
x=2
y=-1
