All you have to do is follow PEMDAS (if you don't know what that is, search it up).
-2-5(4n-6)=-132
Distribute the 5 to everything in the parentheses.
-2-20n+30= -132
Combine like terms.
-20n+28 = -132
Subtract 28 from both sides.
-20n = -160
Divide by -20 on both sides.
n = 8
Answer:
Quotient: d = 1
Step-by-step explanation:
If we apply the formula
(D / d) = C + (R/d)
then
(x-6)/(x-8) can be rewrite in a way that is more convenient
(x-8+2)/(x-8) = (x-8)/(x-8) + (2/(x-8)) = 1 + (2/(x-8))
we can say that
C = 1 (the quotient)
and R = 2 (the rest)
Answer:
To find the inverse, you still interchange the variables
f - 1 (x) = 3 + x/2 - x is the Answer Hope this helps :)
Step-by-step explanation:
Hello, and welcome to Brainly!
To answer this question, you must first isolate the given variable, a. Treat the < sign as an equal sign, in that what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& roots)
Multiplications
Divisions
Additions
Subtractions

First, subtract 8a and add 6 to both side inequality.
a (-8a) - 6 (+6) < 15 (+6) + 8a (-8a)
a - 8a < 15 + 6
-7a < 21
Next, isolate the variable, a, by dividing -7 from both sides of the equation. Note that, when dividing or multiplying by a negative number, you must flip the sign:
(-7a)/-7 < (21)/-7
a < 21/-7
a > -3
a > -3 is your answer.
