Answer:
y = 3x
Step-by-step explanation:
The standard format of a directly proportional equation goes by the format of y = k × x. The question asks us to write an equation if y = 75 when x = 25 and y varies directly with x.
So we substitute the values y = 75 and x = 25 in the equation y = k × x
K = constant, we have to work this out
75 = k × 25
75 ÷ 25 = k
k = 75 ÷ 25
k = 3
k = 3 So then we put this back into the original y = k × x to find our final equation which is y = 3x
8 + 12 + 20
20 - 9 = 11
11 - 2 = 9
Hope this helps! :)
Answer:
Radius
Step-by-step explanation:
The answer is radius.
Answer:
5
Step-by-step explanation:
4x-10=2x - Original equation
4x=2x+10 - Move constant to the right-hand side and change its sign
4x-2x=10 - Move variable to the left-hand side and change its sign
2x=10 - Combine like terms and divide both sides by 2
x=5 - Answer
