Answer:
Step-by-step explanation:
Given
x 2 4 6 8
y 1 2 3 4
Required
Determine the constant of proportionality (k)
The relationship between x and y is:
When y = 1, x = 2;
So, we have:
Make k the subject
Hence, the constant of proportionality is 1/2
Answer:
square root of 31 inches
Step-by-step explanation:
Since a square has 4 equal sides, that means that the area has to be x^2=31, and since 31 isn't a perfect square it's the square root of 31
I'm guessing the brother who is 95 is oldest, so all we have to do is subtract 7 from 95 which is 88.
So Trina should be 88. or x = 88
Correct because 1 and angle 2 are vertical angles then angle 1 and angle 2 are congruent
We know that 36 less than three times a number is equal to the number. This statement can be represented by the following equation:
x = 3*x - 36
Solving the above equation:
⇒ 36 = 2*x
⇒ x = 18
Hence, the number is 18
