Answer:
(1,4)
Step-by-step explanation:
Which ordered pair is a solution of the equation? y = 7 x − 3
a. (1,4) b. (-1,-4) c. both d. neither
Solution
y=7x-3
Solve by trying each ordered pair
a. (1,4)
x=1, y=4
Substituting the value of x and y into the equation
y=7x-3
4=7(1)-3
4=7-3
4=4
This is a true statement
b. (-1,-4)
x=-1, y=-4
Substitute the value into the equation
y=7x-3
-4=7(-1)-3
-4= -7-3
-4= -11
This is not a true statement
This true statement is when x=1 and y=4
So, the ordered pair (1, 4) is the solution

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
One batch = 1/4
One whole cup is 4 batches
3/4 a cup is 3 batches
If you add together one and 3/4 you get 7 Batches
