Answer:
a. n=8
Step-by-step explanation:
to solve an equation, we must do the same operations to both sides.
step 1- add 8 to both sides. now n/4-8=-6 becomes n/4=2
step 2- multiply both sides by 4. so n/4=2 becomes n=8, which gives us our answer.
Answer:
Like terms are terms that contain the same variables raised to the same power. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily. To combine like terms, we add the coefficients and keep the variables the same.
Multiply both the numerator and denominator by 100
the answer is
645/500
Divide the numerator by 5 and the denominator by 5 to get
129/100
Simplify to get
1.29
Answer:
k=3
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In this problem we have
therefore
The constant of proportionality is k=3
