Negative ten times a number minus five equals negative eleven times the same number.

121

Step-by-step explanation:

-10 x 0.6 = -6.

-6 - 5 = -11

-11 x -11 = 121

-10n - 5 = -11n

n = 5

Step-by-step explanation:

Times = multiplied by

Minus = subtract

Let n = the number

Negative ten times a number:  -10 x n = -10n

minus five:  - 5

equals:  =

eleven times the same number: 11 x n = 11n

Therefore:  -10n - 5 = -11n

To solve  -10n - 5 = -11n

Add 11n to both sides:

⇒ -10n - 5 + 11n = -11n + 11n

⇒  n - 5 = 0

Add 5 to both sides:

⇒  n - 5 + 5 = 0 + 5

⇒  n = 5

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

the answer is 21%.
