Answer:
y = 
Step-by-step explanation:
Straight line in the graph attached shows the linear relation between number of gallons of white paint and number of gallons of red paint added to prepare pink.
Let the number of gallons of white paint required = x
and number of gallons of red paint required = y
y ∝ x
y = kx [k = proportionality constant]
Since a point (4, 1) lies on this line,
1 = 4k
k = 
Therefore, equation that describes the relationship will be,
y =
Answer:
1 1/3
Step-by-step explanation:
First, distribute the parenthesis.
Second, multiply the fractions.
Third, add the 2 values together to get your answer in improper form.
Lastly, turn the improper fraction into mixed form.
The answer I got is y= 1/3x + 5
Answer:
x = 25
Step-by-step explanation:
Since ∠ A = ∠ B then the triangle is isosceles and AC = BC , that is
4x - 30 = 2x + 20 ( subtract 2x from both sides )
2x - 30 = 20 ( add 30 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
