As we already have the value of y,we can put it into another equation.
Here's how we can solve the equation:
y = 2x+48...(1)
y = 8x...(2)
Put (2) into (1)
(8x) = 2x+48
8x-2x = 48
6x = 48
x = 8...(3)
Put (3) into (1)
y = 8(8)
y = 64
Thus, x=8, y+64
Hope it helps!
Answer:
x 100 = 80%
Step-by-step explanation:
Answer:
63
Step-by-step explanation:
the first one is 9x bigger then the second one
so 7x9 is 63
Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 =
( multiply both sides by 3 )
24 = k
y =
← equation of variation
