Answer:
y = -28 ÷ x
Step-by-step explanation:
The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.
So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x
K = constant, we have to work this out
7 = k ÷ -4
7 × - 4 = k
k = - 4 × 7
k = -28
k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x
Answer:
3.5 times 2 equals 7 so try 2.5 times 2 which would be 5, 5 could be the answer but im not sure :)
The answer would be 2.
65 x 32 = 2080.
(65 × 30) = <span>1950</span><span>
(65 × 2) = 130
1950 + 130 = 2080
To make this easier, you can 30 from 32.</span>
They are variables they can equal anything. it is just an example of two different fractions who's numbers are unknown.
