7.72 convert the nickels and dimes into pennies, add that to the other number of pennies and divide that by 100
Answer:
x = 
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6 when x = 2, then
- 6 = 2k ( divide both sides by 2 )
- 3 = k
y = - 3x ← equation of variation
When y = - 22, then
- 22 = - 3x ( divide both sides by - 3 )
x =
= 
Answer:
568
Step-by-step explanation:
because we multiply the 64 with the number that will be in the number
I don't really understand what you are looking for but from what i understand, the answer would be 3k - 2
-3t+11>20
add 3t to both sides
11>20+3t
minus 20 both sides
-9>3t
divide both sides by 3
-3>t
t<-3
