Alright so -3 to the power of -3 would equal -27 then you would do -27 divided by 6 which would equal -4.5 then you would multiply -4.5 twice to get 18
Answer:
B.
Step-by-step explanation: it is A. not B.
6x+15y=-45
<span>6x+5y=-35
subtract second equation from the first
</span>6x+15y=-45
<span>6x+5y=-35
</span><u>- - +
</u> 10y = -10
⇒ y = (-10/10) = 1
put value of y in one of the equation,
6x+5y = -35
⇒ 6x + 5(-1) = -35
⇒ 6x - 5 =-35
⇒ 6x = -35 + 5 = 30
⇒ x = 30/6
⇒ x = 5
So x=5 and y=-1.
X - 3 = -32 move the constant to the right
X = -32 + 3
Answer : X = - 29
Answer:
Step 2
Step-by-step explanation:
In step 2 the expression was 40+20 which would have been 60 but he might have thought addition sign was subtraction so he did 40-20 which is 20 so he is wrong made mistake in step 2
