Answer:
Stephanie has more than $900
Step-by-step explanation:
Represent the unknowns: a for Alexandra and s for Stephanie.
Then a + s > $2,500, and a = s + $700.
Substituting the latter into the former equation, we get:
(s + $700) + s > $2,500, or
2s > $1800
Then s > $900; Stephanie has more than $900.
3x - 7 + 6 = 7x + 6
First shift all the pure numbers to one side
3x = 7x + 6 + 7 - 6
Now add up the pure numbers
3x = 7x + 7
Shift the 7x to the other side
3x - 7x = 7
-4x = 7
Divide 7 by - 4
X = - 1.75

Answer:
That would be Option C.
Step-by-step explanation:
Lets look at y = 4x + 2:-
Let x = a then y = 4a + 2
Now if x in creases to a +2, y = 4(a +2) + 2 = 4a + 8 + 2
= 4a + 10.
(4a + 10) - (4a + 2) = 8 , so this is the required expression, y = 4x + 2.
