Answer:
The constant of proportionality would just be 12.9.
Step-by-step explanation:
This equation is already simplified enough to were the constant of proportionality is just the number attached to the x.
Answer:
the goal is to try and get x alone. For the 1st problem, x=3.
Step-by-step explanation:
3x + 1 = 10 Subtract 1 both sides to cancel out the 1 on the left side. 10-1 = 9
3x = 9 To get x alone here, Divide 3 on both sides. 9/3 = 3
x = 3 Now x is alone, which means x = 3.
This is right because if you plug x with 3, the sum = 10.
(3*3) + 1 =10
9 + 1 = 10
So, that's how you know 3 is the right answer.
Answer:
Option B
Step-by-step explanation:
we know that
A <u>rational number</u> is one that can be represented as the ratio of two whole numbers
so
-----> Is not a rational number, because √5 is not a whole number, is a irrational number
---> Is a rational number, because can be represented as the ratio of two whole numbers
therefore
√5/8 is irrational and √4/9 is rational
