Please help ! :0 -17 = 2y/3 + 3y/4

VashaNatasha [74]

Hi,

Equation;

$- 17 = \frac{2y}{3} + \frac{3y}{4}$

Solving:

$- 17 = \frac{2y}{3} + \frac{3y}{4} \: \: \: | \div 12 \\ - 204 = 8y + 9y \\ - 204 = 17y \\ 17y = - 204 \: \: \: | \div 17 \\ \\ y = - 12 \: \: \: \: \: \: \: \: (result)$

Hope this helps.

A number is selected at random from the set {2, 3, 4,. 10}. Which event, by definition, covers the entire sample space of this e

Citrus2011 [14]

The event by definition that covers the entire sample space of the experiment is;

The number is even or less than 12

We are given the numbers in the set as;

set {2, 3, 4,... 10}.

Now, the numbers in the set are even and odd numbers from 2 to 10 with 10 being the highest and 2 being the lowest.

Thus the event that covers this sample space is simply a set of numbers that are even or less than 12.

We know that a triangle has 3 sides right?

Well, if the perimeter is 39 and there are 3 sides you would divide 39 by the 3 sides

39/3=13

Therefore, one side of the triangle would equal 13
