Step-by-step explanation:
65.5/100=0.655
Answer:
A
Step-by-step explanation:
Given
- 1 ← a difference of squares which factors in general as
a² - b² = (a - b)(a + b)
here = (x²)² ⇒ a = x² and b = 1
- 1 = (x² - 1)(x² + 1)
x² - 1 ← is a difference of squares and factors as
x² - 1 = (x - 1)(x + 1), so
(x² - 1)(x² + 1) = (x - 1)(x + 1)(x² + 1), hence
- 1 = (x - 1)(x + 1)(x² + 1) → A
Answer:
5+2y=13 is linear
y=+7 is linear
y-5=2(x-1) is linear
=x+7 idk this is not complete so i cant answer it
x=-4 is linear
HOPE IT HELPED<3 tell me if I am wrong.

Answer:
<em>D. 69 Km</em>
Step-by-step explanation:
<u>Scaling</u>
Maps usually represent real areas on the field, but since they cannot fit in pieces of paper, we use scales where sizes and distances are all proportional to the real measurements.
On the map of the question, we know 1 cm represents 30 Km. It means that we can know approximate real distances by measuring the distances on the paper or blueprints.
Two cities are 2.3 cm apart on the map, it means that they are really 2.3*30 =69 Km apart
25/5 = 5......so the unit rate is 5 teaspoons per cup
