Answer:

(-6)(-5)(3)(-2)(4) = -720

Step-by-step explanation:

-6 time -5 is positive 30 beacuse 2 negatives make a positive

30 times 3 is 90

90 time -2 is -180 because a negative times a positive is a negative

-180 times 4 is -720 :)

Answer:

-720

Step-by-step explanation:

Using PEMDAS, you need to multiply from left to right.

1.) -6(-5) = 30

2.) 30(3) = 90

3.) 90(-2) = -180

4.) -180(4) = -720

Remember:

negative times negative = positive
negative times positive = negative
positive time positive = positive

Lubov Fominskaja [6]

We can solve this problem by using PEMDAS

PEMDAS stands for
Parenthesis
Exponents
Multiply
Add
Subtract

So start with (P+3) () is a parenthesis

Kelly needs to order lunch for orders 6 people at a business meeting. Her menu choices are chicken salad for a cost of $5 per pe

nirvana33 [79]

Ok , with that information we can write the equations
x + y = 6
5x + 4y = 28

Where x = how many people ordered chicken
and y = how many people ordered egg salad

Through elimination , we can set one of the variables in both equations equal so we can eliminate it :

(4)x + (4)y = (4)6
5x + 4y = 28

4x + 4y = 24. equation 1
5x + 4y = 28. equation 2

Now we can subtract the second equation by the first equation and isolate one variable:
equation 2 - equation 1

5x - 4x + 4y - 4y = 28 - 24

x = 4

Now that we discovered our x value ( How many people ordered chicken salad ) , we can apply it to one of the equations and discover y ( how many people ordered egg salad)

x + y = 6
x= 4
4 + y = 6

We can shift 4 to the other side of the equation by subtracting 4 from both sides of the equation:
4 - 4 + y = 6 - 4
y = 2

x=4 and y=2

So the awnser is :
4 people ordered chicken salad and 2 people ordered egg salad!

I hope you understood my brief explanation!!

p.s if you want to know how to use another method to solve these problems ( Substition) , just let me know in a comentary down here
