Answer:
y = 28
Step-by-step explanation:
Given that y varies directly as x and inversely as z then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = 4 when x = 2 and z = 7, then
4 = 
( multiply both sides by 7 )
28 = 2k ( divide both sides by 2 )
14 = k
y = 
← equation of variation
When x = 6 and z = 3 , then
y = 
= 14 × 2 = 28
Assuming the left is minutes and the right is distance, Mario runs 1 mile in 7 minutes
(a) y=x/7
(b) the rate of change is 7
(c) if he ran for 70 minutes then his distance is 10 miles.
*for (c) just plug in the number given. Replace it with x and divide it by 7.*

Answer:
what
Step-by-step explanation:
Answer:
Eight less than four times a number is equal to two times the difference of double that same number decreased by three.
Step-by-step explanation:
The given equation is:
4x−8=2(2x−3)
We will try to translate the given equation in English.
We can see that the variable used is only one. On the left hand side of the equation 8 is being subtracted from 4 times of the variable and on the right hand side 3 is being subtracted from 2 times of variable and then being multiplied by two.
From the given option, correct answer is:
Eight less than four times a number is equal to two times the difference of double that same number decreased by three.
