To solve for any equation with a variable the objective is to get the variable alone. First determine what operation is holding together the 42 and the y. There are no symbols between them so you can conclude they are being multiplied. What is the opposite operation to multiplication, or in other words what undoes multiplication? It’s division. So to get rid of the 42 you divide by 42. What you do to one side you must do to the other. So you main also divide 8256 by 42. So now that the y is alone you know that y=203.

X/6 + 2x/3 = 5 what is the value of x in the equation

ycow [4]

The value of x is 6 in the equation.

Step-by-step explanation:

Given equation is;

$\frac{x}{6}+\frac{2x}{3}=5$

Taking least common multiple

$\frac{x+4x}{6}=5$

Multiplying both sides by 6

$6*\frac{5x}{6}=5*6\\5x=30$

Dividing both sides by 5

$\frac{5x}{5}=\frac{30}{5}\\x=6$

The value of x is 6 in the equation.

A bag contains 7 red and 10 white balls. In how many ways 4 balls are selected if there are more than 2 red balls? (Please solve

erastova [34]

Answer:

385 ways

Step-by-step explanation:

Given;

7 red balls

10 white balls

In how many ways can 4 balls be selected if there are more than 2 red balls.

Selecting 4 balls which must contain more than 2 red balls, will be 3 red balls and 1 white ball to make it 4 in total, or all the 4 balls selected will red balls.

= 3 red balls and 1 white ball OR 4 red balls

= 7C₃ x 10C₁ + 7C₄

$= \frac{7!}{4!3!} *\frac{10!}{9!1!} \ \ + \ \frac{7!}{3!4!} \\\\= (35*10) \ + \ 35\\\\= 350 \ + 35\\\\= 385 \ ways$

Therefore, there are 385 ways of selecting 4 balls, if there are more than 2 red balls.
