Answer:
13
Step-by-step explanation:
4+(-3)-2*(-6)
Let us start from the left
2*(-6)= 2 times 6 , where we will have a negative sign on the result as + when multiplied by - gives - (negative)
2*(-6)=-12
4+(-3)-2*(-6) = 4+(-3)-(-12)
Now we open the bracket from the left. It the sign outside the bracket is negative the sign in the bracket will be changed
Hence
4+(-3)-(-12)= 4-3+12
Now -3 +12 we find the difference as the signs are opposite and then place the sign with the larger number
Hence -3+12=9
4-3+12=4+9 = 13
Answer:
Janet has coins worth 252.5, 101, and 50.5.
Step-by-step explanation:
Let us call the three coins 
, and 
.
The first coin 
is 5 times another coin<em> (let's say </em>
); therefore,
,
and the third coin is 2 times the value of another coin<em> (it's coin </em><em>):</em>
<em />
<em>.</em>
The total worth of all coins is 404; therefore,
or
with the value of in hand, we find and :
and for 
Thus, Janet has 3 coins worth 252.5, 101, and 50.5.
Answer:
Quadrant II
Step-by-step explanation:
(-5,6)
The x coordinate is negative so the quadrant is either 2 or 3
The y coordinate is positive so the quadrant is either 1 or 2
To make both happen, it must be in quadrant 2
Quadrant II
