Answer:
I'm pretty positive it's All real answers?
Answer: x=-12
Step 1: Simplify both sides of the equation.
4x+27=−33−x
4x+27=−33+−x
4x+27=−x−33
Step 2: Add x to both sides.
x+27+x=−x−33+x
5x+27=−33
Step 3: Subtract 27 from both sides.
5x+27−27=−33−27
5x=−60
Step 4: Divide both sides by 5.
x=−12
90b + 150g > 500

Answer:
y = 10
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 20 when x = 4 and z = 3 , then
20 = k × 4 × 3 = 12k ( divide both sides by 12 )
= k , that is
k = 
y =
xz ← equation of variation
When x = 2 and z = 3 , then
y =
× 2 × 3 = 5 × 2 = 10
