Answer:
the starting number is 751
Step-by-step explanation:
multiple 20 × 4 and get 80 then add to 671 which is 751
Find the unit costs and compare them:
$1.99
---------- = $0.199/oz
10 oz
$2.99
-------------- = $0.17/oz
18 oz
Clearly, the 18 oz bag for $2.99 is the better buy, at $0.17/oz versus $0.199 oz for the 10 oz bag for $1.99.
Answer:
x = - 8/23
y = 40/23
Step-by-step explanation:
-5x- y = 0
and
-8x+3y = 8
The first step to solve this would be to get what one of the two variables equal. The easiest in this case is y from the first equation.
-5x-y = 0
-y = 5x
y = - 5x
Now you can take this y value and plug it into the section equation.
-8x + 3(-5x) = 8
-8x - 15x = 8
-23x = 8
x = - (8/23)
Once you get the x value you can plug it back into equation one to get y's value
-5*-(8/23) - y = 0
40/23 - y = 0
y = 40/23
Everything should be capitalized. If "dear" is the beginning of a sentence, it should be capitalized. "aunt" and "mary" are a name so they should be capitalized too.
