Want this question answered?
y varies directly as x so y = cx for some constant c. y = 125 when x = 25 so 125 = c*25 so that c = 5 ie the relationship is y = 5x Then when x = 2, y = c*x = 5*2 = 10
5 x 5 = 25 25 x 25 = 625
It is: (5*10)-25 = 25
The face value is 5, the place value is units.
5 + 20 = 25

We write y=kx since y varies directly as x. Now we know if x is 5, y is 10. so we write 10=5k so k=2
If y varies directly as x then k = 2.
y = -5
the value and place value of 2 in 25 is tens and 20. the value and place value of 5 in 25 is units/ones and 5.
Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35
5 x 5 = 25 25 x 25 = 625
It is: (5*10)-25 = 25
The face value is 5, the place value is units.
The price of a 100g parsnip typically ranges from 5 to 25 cents. The actual value varies based on where it is being sold and current market conditions.
5 + 20 = 25
Multiply them. 1/5 x 25 = 5
