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

Simplify

Scorpion4ik [409]

Answer:

Step-by-step explanation:

using the rule of exponents

$(\frac{a}{b}) ^{-1}$ = $\frac{b}{a}$ , then

$\frac{123}{321}$ × $\frac{456}{654}$ × $\frac{789}{987}$ × $\frac{321}{123}$ × $\frac{654}{456}$ × $\frac{987}{789}$

[ $\frac{123}{321}$ × $\frac{321}{123}$ = 1 , $\frac{456}{654}$ × $\frac{654}{456}$ = 1 , $\frac{789}{987}$ × $\frac{987}{789}$ = 1 ]

= 1 × 1 × 1

= 1
