Answer:
x-0.33x = 0.67x
Step-by-step explanation:
Given : A new soup recipe contains 33% less sodium per serving than the old soup recipe.
The old soup recipe contained x milligrams of sodium per serving.
To Find: Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe
Solution :
Since we are given that old recipe contains x milligrams of sodium per serving
And new recipe contains 33% less sodium per serving than the old soup recipe.
So, 33%of x = 0.33x
Since new recipe contains 33% less sodium than old recipe:
⇒x-0.33x
or
⇒(1-0.33)x
⇒0.67x
Thus expressions which could represent the amount of sodium per serving, in milligrams, in the new soup recipe :
x-0.33x or 0.67x
Answer:
The sum of a and b is 12.
Step-by-step explanation:
Try drawing this figure. ABCD would actually be a triangle, rather than the common quadrilateral you would expect - considering there are 4 points plotted. Therefore, we would have to find the distance between respective points ( 0, 1 ) and ( 2, 5 ) / ( 2, 5 ) and ( 7, 0 ) / ( 0, 1 ) and ( 7, 0 ). Let's apply the distance formula and calculate the distance between each point, therefore determining the perimeter.
Distance between points ( 0, 1 ) and ( 2, 5 )
= 
= 
= 
= 
= 
Distance between points ( 2, 5 ) and ( 7, 0 )
= 
= 
= 
= 
= 
And you can calculate the distance between points ( 0, 1 ) and ( 7, 0 ) to be exactly as well. Therefore, you can say that the perimeter of this triangle is 
= 
. Note that this is similar to the form we are given. Thus, a = 10, and b = 2 - making it's sum 10 + 2 = 12.
