lmk if it’s the wrong answer
Well to find out if they simplify to -1, work out the expression
A) -1(1-1)
simplify inside the parenthesis
-1(0)
anything times 0 is 0
B) -(-1)(-1)
this one simplifies to -1
C) <span>(− 1) + 1 − 1 (− 1)
PEMDAS
-1 + -1
2
then work from left to right
-1 + 1 is 0 plus 1 is 1
D)</span><span>− (− 1) − (− 1)(− 1)
PEMDAS so do Multiplication first
-(-1) is 1
1 - (-1)(-1)
-1*-1 is 1
1-1 is 0
</span>
The answer to this question is B
Hope this helps :)
Answer:
15 Poses
Step-by-step explanation:
SInce he can teach 30 poses in 60 minutes and if the class time is cut by half then the poses are cut by half. Look below.
Minutes : 60/2 = 30 minutes
Poses : 30/2 = 15 poses
Answer:
X= -5/3 Y= 10/3
Let me know if you need the work to be shown
Answer:
The statement is wrong. a-b can be positive but not always.
Step-by-step explanation:
There can be three possible situations that are:
- a>b
- a<b
- a=b
Now taking first condition, the result will be positive because a smaller integer is subtracted from a greater one. Such as 5-2=3
In second condition, the result will be negative because a greater integer is subtracted from smaller one. Such as 2-5= -3
In the third condition, the result will always be zero because both the integers will cancel each other. Such as 5-5=0
