Its 5 because you have to change 28 into a fraction by putting a one under like so 28/1
Answer: x = 120 y = 25 z = 35
Step-by-step explanation:
z = 35 because of the Z rule
y = 25 because y + 35 = 60
x = 120 because of the C rule
Sorry if you don't understand, I don't know how to explain the reason to the answers
Answer:
The answer is [B Josh, because when dividing by a power of 10, the decimal moves to the left]
Answer:
x=18
Step-by-step explanation:
S=(n-2)180
S=(5-2)180
S=3x180
S=540
540=(9x-6)+(3x+23)+95+((7x-4)+90
540=19x+198
540-198=19x
342=19x
342/19=x
x=18
Answer:
vertex = (- 1, 1 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - 
y = x² + 2x + 2 ← is in standard form
with a = 1 and b = 2 , then
x = - 
= - 1
substitute x = - 1 into the equation for y- coordinate of vertex
y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1
vertex = (- 1, 1 )
