Answer:
a = -1
Step-by-step explanation:
First, combine like terms. Like terms are terms with the same amount of the same variables.
6a + 5a = -11
(6a + 5a) = -11
(11a) = -11
Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Divide 11 from both sides:
(11a)/11 = (-11)/11
a = -11/11
a = -1
a = -1 is your answer.

Answer:
Step by-step explanation:
Speed v = 12km/h = 12/60km/min
Time t = 75min =
Distance d = ?
V = d/t
12/60 = d/75
Cross multiply
60d = 75 × 12
60d = 900
d = 900/60
d = 15km
Qué quieres decir con eso? what is the natural number of what??
3/11 = 3/11 × 100 % = 300/11 % = 27.2 %
