<span>T = 3U / E solve for U
3U = T * E
U = (</span>T * E)/3
U = 1/3(TE)
Answer:
v=0.79x+3.99
f=1.89x+5.49
combined cost: 2.68×+9.48
8/10 or 4/5 is what makes up the remaining oceans
Given : y = -25 and x = -5
We can notice that if we Multiply 'x' with 5 we get 'y'
That is (-5) × 5 = -25
⇒ x multiplied by 5 = y
(a) The Equation that relates x and y is 5x = y
(b) We found that the Equation of this Direct variation is : 5x = y
The Question is to find the value of y when x = 3
The Value of y at x = 3 can be found by simply substituting x = 3 in the equation we found.
⇒ y = 5x
⇒ y = 5 × 3
⇒ y = 15
So, the Value of y when x = 3 is 15
