Evaluate.<br> 6[5(3-9)-1]+2 the answer of this divided by the answer of this one 7(8-2)+4
Snowcat [4.5K]


According to PEMDAS, these are the steps for evaluating this equation -

3-9=-6

-6 x 5 = -30 - 1 = -31

-31 x 6 = -186, + 2 = -184

Now our first answer is -184 (I think this is correct)

Next thing we'll do is the second equation

8-2 = 6

6 x 7 = 42

42 + 4 = 46

Now, we can divide :)           -184 / 46 equals -4

Hope this helps :D!

HELP<br> Solve the following systems using the elimination method.<br> 5x+2y = -16<br> 4x-2y = 16
velikii [3]

Answer:

x= 0 , y= -8

Step-by-step explanation:

Add the 2 equations together, you would get:

9x = 0

Divide both sides by 9:

x = 0/9

x=0

Substitute the value of x in one of the equations to get the value of y, I picked the first one (5x+2y = -16)

5(0) +2y = -16

0+2y = -16

2y = -16

Divide both sides by 2:

y = -8

Ther are 6 girls and 7 boys in a class. A team of 10 players is to be selected from the class. How many different combinations o
omeli [17]

Answer:

There are 286 possible combinations

Step-by-step explanation:

To solve this problem we must use the formula of combinations.

nCr =\frac{n!}{r!(n-r)!}

Where n is the number of players that there are and elect r of them

In this case there are 7 + 6 = 13 players and you choose 10 of them

Then we look for  13C10

13C10 =\frac{13!}{10!(13-10)!}

13C10 =\frac{13!}{10!*3!}

13C10 =286

There are 286 possible combinations
