22 would be the answer. You reverse the equation so you multiply 3 and add 7 5x3 = 15 15+7= 22

7 points!

Travka [436]

It is the plus minus sign. It means to do the addition and subtraction.

Examples:

10 ± 7 = 17 and 3

15 ± 5 = 20 and 10

100 ± 90 = 190 and 10

It is generally used to indicate a possibility of two outcomes. A negative or positive outcome.

Isolate I for the literal equation V = IR

Anit [1.1K]

In order to isolate any term from an equation we need to clear out any different variable or numbers different from the one we want

$V=IR$

in this case I is being multiplied by R, so we need to do the opposite which is divide in order to eliminate

$V=\frac{IR}{R}$

But since this is an equality we must do it on both sides so de equation does not get altered

$\frac{V}{R}=\frac{IR}{R}$

Then we simplify the equation

$I=\frac{V}{R}$

Evaluate the expression. StartFraction 9 factorial Over 3 factorial EndFraction 3 6 60,480 362,874

REY [17]

Answer:

60,480 is the correct answer.

Step-by-step explanation:

First of all, let us have a look at the formula of factorial of a number 'n':

$n! = n \times (n-1) \times (n-2) \times ...... \times 1$

i.e. multiply n with (n-1) then by (n-2) upto 1.

Keep on subtracting 1 from the number and keep on multiplying until we reach to 1.

So, $9!$ can be written as: $9 \times 8 \times 7 \times ...... \times 1$

Similarly $3!$ can be written as: $3 \times 2 \times 1$

Re-writing $9 !$ :

$9 \times 8 \times 7 \times ...... 3 \times 2 \times 1\\\Rightarrow 9 \times 8 \times 7 \times ...... 3 !$

Now, the expression to be evaluated:

$\dfrac{9!}{3!} = \dfrac{9 \times 8 \times 7 \times ..... \times 3!}{3!}\\\Rightarrow 9 \times 8 \times 7 \times 6 \times 5 \times 4\\\Rightarrow 60480$
