1/2r -3= 3 (4-3/2r) is to be solved for r.
I'll begin by making the assumptions that by 1/2r you actually meant (1/2)r and that by 3/2r you actually meant (3/2)r. When in doubt, please use parentheses to make your meaning clear.
Thus, 1/2r -3= 3 (4-3/2r) becomes (1/2)r -3= 3 (4-(3/2)r ) .
Simplify this by multiplying all 3 terms by 2. Doing this will eliminate the fractions:
r -6 = 3 (4*2-(3)r ) or r - 6 = 24 - 9r
Now expand the right side, using the distributive property of
r - 3 = 24 - 9r
Regrouping so as to combine like terms:
10r = 30
Solving for r: r = 30/10 = 3
The value of r that satisfies this equation is 3
The smallest value squared would be sqrt0 or 0. Please mark Brainliest!!!
To determine the distance between two points, we use the equation,
distance = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values for the abscissa and ordinates of the points,
distance = √(0 - 2)² + (0 - 5)² = √29 ≈ 5.39
Therefore, the distance between these two points is approximately equal to 5.39.
Hi there!
The formula for the perimeter of a rectangle is P = 2 (l + w).
We can simplify this formula so that we can find the solutions easier.
P = 40
40 = 2 (l + w)
divide both sides by 2
40/2 = l + w
20 = l + w
So the length + width has to equal to 20.
So your answers would be B , C , D.
Hope this helped! :)
Felix and Tyler means
Mean = (9.4+54)/2= 31,7
Median= (7+66)/2= 36,5
Is this what you are looking for??
