Answer:
D S = (1 - 0.2)g
Step-by-step explanation:
The original price of the guitar was g.
She paid 0.8g.
0.8g = 0.80g = 80% of g
If she paid 80% of the price, that means the discount was 20%.
100% - 20% = 1 - 0.2
Subtracting 20% form the whole 100% of the price is the same as subtracting 0.2 from the whole price of 1.
Answer: D S = (1 - 0.2)g
Answer:
2f =c
350c + 500f = 4800
Step-by-step explanation:
Twice as many cans of soup as frozen dinners
All food combined contain 4800 (mg of sodium)
2f =c
350c + 500f = 4800
These are the systems of equations.

Step-by-step explanation:
Answer:
x = -
Step-by-step explanation:
Given
9x² + 30x + 25 = 0 ← left side is a perfect square
(3x + 5)² = 0, thus
3x + 5 = 0 ⇒ 3x = - 5 ⇒ x = -
solution is x = - with multiplicity 2
