Answer 1

Can someone help me?

Answer 2

well multiplication goes first so it would be
-20+ (-2) . (-6)
-20 + (12) (two negatives make a positive)
-8

Answer 3

okay so it would be

Answer 4

c

Answer 5

why?

Answer 6

why c?

Answer 7

Well like i said multiplication goes first before adding or subtracting

Answer 8

yes

Answer 9

okay

Answer 10

so when you multiply -2 and -6
it becomes +12 because 2 negatives make a positive

Answer 11

oooohhhhhh

Answer 12

so you are left with -20 + 12
and then you find the difference
which would be -8

Answer 13

okay

Answer 39

yes

Answer 40

alright what do you do next

okay that means it is...

Answer 44

-62?

Answer 45

Yes, so
14-62= ?

Answer 46

I thought it was -62?

Answer 47

-62 is 6.2(-10)

Answer 48

yes, but dont forget the 14- at the beginning

Answer 49

back to the equation there' still a 14

Answer 50

?

Answer 51

14 - 6.2 X (-10) we simplified 6.2 x (-10) but see the 14 at the beggining

Answer 52

yes

Answer 53

14 - 6.2 * (-3 + -7) <---- that was the equation
14 - 6.2 * (-10) <------ first step ( added the parenthesis)
14 - 62 <----- second step (multiplied)
-48 <----- find the difference (add)

Answer 54

okay

Answer 55

so, 76

Answer 56

no I already gave you the answer -48
14-62 = -48

Answer 57

okay

Answer 58

I have a question that is a little different than the other question.

Which expressions, when evaluated with z = 8, are negative in value?

Choose all answers that are correct.

A.
–2z – 14

B.
–25 + 4z

C.
–2z + 15

D.
30 – 3z

Answer 59

just plus 8 into each answer and see which one comes out with a negative answer

Answer 60

ooooohhhhh
okay so the answer is...

Answer 61

so
1. -2z - 14
-2(8) - 14
-16 - 14
-30

so #1 is one of the answers

Answer 62

Is it a?

Answer 63

yes

Answer 64

there's more than one answer so A is one of them

Answer 65

okay so the other one is...

Answer 66

the next one is c, -2(8)+15=-1

Answer 67

B. -25 + 4z
-25 + 4(8)
-25 + 36
11
B. is not one of the answers

Answer 68
