Rewrite 5/6 with the denomintaior of 12

svp [43]

To change 5/6 to a fraction with a denominator of 12, you need to do one step. Since 12 is a multiple of 6 (meaning that it can be multiplied by 6 and another number), you multiply 5/6 by 2 to get 10/12. 10/12 is your answer.

Jamal is running 42 kilometers. The amount of time t it takes Jamal to run varies inversely with the rate, r, at which he runs,

leva [86]

Answer:

t α 1 /r ; t = k/r

Step-by-step explanation:

Given that :

Time taken, t varies inverse as rate, r

MATHEMATICALLY,

t α 1 /r

Hence,

t = k/r ;

Where, k is the proportionality constant

Hence, the situation could be expressed as :

t = k/r OR

t α 1 /r

In a class of 7 students there are 4 that play soccer.

Anton [14]

Answer:

Step-by-step explanation:

The total number of ways to draw 3 students is 7*6*5 = 210

Order does not matter. There are 3 students that don't play soccer.

P(3 don't play soccer) = 3*2 * 1 / 210 = 1/35 = 0.02857

For each equation, find y when x=-3. Then find x when y = 2 1. y = 6x + 8

crimeas [40]

⬇ Hey, the answer is down below! :) ⬇

For y: x = -3

For y it stays the same.

For x: y = 2

For x it stays the same too.

For 1.): $x = \frac{1}{6}y + \frac{-4}{3}$

Step-by-step explanation:

For y there is no step-by-step explanation unfortunately.

For x there isn't a step-by-step explanation too unfortunately.

⬇ For 1.) there is a step-by-step explanation! ⬇

For step 1 we should flip the equations.

6x + 8 = y

For step 2 we should add -8 to both sides.

6x + 8 + − 8 = y + −8

= 6x = y − 8

For step 3 we should divide both sides by 6.

$\frac{6x}{6} = \frac{y - 8}{6}$

= x = $x = \frac{1}{6}y + \frac{-4}{3}$

In result we should have $x = \frac{1}{6}y + \frac{-4}{3}$ as the answer!
