Answer:
-4.5
Step-by-step explanation:
I added 3.25 and .5=3.75. Then i did 0.25*-6=1.5. -1.5+3.75=2.25. 2.25*2=-4.5
Negative
basically
negative means change sign
positive means do nothing
change sign times do nothing=change sign=negative
basically
(+)(+)=(+)
(-)(-)=(-)
(+)(-)=(-)
(-)(+)=(-)
and
(+)/(+)=(+)
(-)/(-)=(-)
(+)/(-)=(-)
(-)/(+)=(-)
answer is negative
<em>Answer</em>
3
<em>Explanation</em>
Let's start by factoring the expression; 3x + 24.
3 is common in both term. So, factor it out.
3x + 24 = 3(x + 8)
The number that would fill in the blank to complete the factorization of 3x+24 is 3.
7)
17x + 3 = 54
17x = 51
x = 3
4y - 3 = 57
4y = 60
y = 15
8)
4x - 3 = 45
4x = 48
x = 12
180 - 45 - 41 = 84
11y + 6 = 94
11y = 88
y = 8
Multiply 3x +y =23 by -4
x+4y=4
-12x+(-4y)=-92
Add together
-11x = -88
x = 8
Plug x in to find y.
8 + 4y = 4
Subtract 8 from each sides
4y = -4
Divide by 4
y = -1
So the answer is x =8, y= -1
I hope that helps!
