When y = 35,x = 2.5. If the value of y varies directly with x what is the value of y when the value of xis 3.25
leonid [27]

Answer:

The value of y would be 45.5

Step-by-step explanation:

To solve this problem, start with the base form of direct variation.

y = kx

Now we can use our original values to model the equation and find k.

35 = k(2.5)

14 = k

Now we can model the equation as:

y = 14x

Now to find y, when x = 3.25, simply put 3.25 into the equation.

y = 14(3.25)

y = 45.5

I need someone to solve this
LUCKY_DIMON [66]

Answer:

?? = 900

Step-by-step explanation:

Solve algebraically

let x be ball and y be cube

x + y = 100

x - y = 80

xy = ??

We can solve by elimination. Eliminate one of the variables by adding OR subtracting the entire equations. I will add.

.     x + y = 100

<u>+    x - y = 80</u>       y + - y = y - y = 0; The variable is eliminated

.        2x = 180      Divide both sides by 2 to isolate x

.          x = 90

Substitute x = 90 into one of the equations.

x + y = 100

90 + y = 100  Isolate y by subtracting 90 from both sides

y = 100 - 90

y = 10

Find xy = ?? by substituting y for 10 and x for 90.

xy = (90)(10) = 900

Therefore the value of ?? is 900.
