The probability of the 2 events are multiplied to get the result 10/91

so we have the relation 5/14 * x = 10/91

where x is the probability of drawing the second black

so x = 10/91 * 14/5 = 4/13 answer

Meg and Tanner take a road trip together where they take turns driving. The ratio of the number of miles that Meg drives to the

frez [133]

Answer:

Step-by-step explanation:

$\frac{Meg}{Tanner}$ = $\frac{4}{3}$

total dist. driven = dist. Meg drove + dist. Tanner drove

Meg = 112

Tanner = x or how far did Tanner drive?

$\frac{112}{x}$ = $\frac{4}{3}$

$\frac{3}{4}$ * 112 = x

84 =x so Tanner drove 84 miles

total driven = 112 + 84

total driven = 196 :)

Need help how do I do this, start it, and the steps please

Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

Let's first write down the equation we are going to solve.

( 1 / 3 )h - 4 [ ( 2 / 3 )h - 3 ] = ( 2 / 3 )h - 6

To begin with, we will expand the brackets => [ ]

( 1 / 3 )h - ( 8 / 3 )h + 12 = ( 2 / 3 )h - 6

Next we will collect like terms by placing all the individual numbers on the right-side of the equation and the terms with ( h ) on the left-hand side of the equation so that we can begin making ( h ) the subject.

( 1 / 3 )h - ( 8 / 3 )h - ( 2 / 3 )h = - 6 - 12

Then we will simplify both the left-hand side and right-hand side of the equation to solve it for ( h ).

( - 9 / 3 )h = - 18

- 3h = - 18

h = - 18 / - 3

h = 18 / 3

h = 6

FINAL ANSWER:

Therefore, the answer is:

h = 6

Hope this helps! :)
