3x + 4y = 31
2x - 4y = -6
*The +4 and -4 in the center of the equation cancel out because 4-4 = 0*
3x = 31
2x = -6
------------
*add like terms*
3x + 2x = 5x
31 - 6 = 25
So now you should have this written on your paper ... > 5x = 25
*Divide by 5 on each side*
5x = 25
_ _
5 5
x = 5
The one that makes the most sense is C
Answer:
16 bags
Step-by-step explanation:
To find this, we <em>divide 2 over 1/8</em>, to see how many <em>units of 1/8 fits into that of 2</em>.
can be rewritten as <em>2*8</em>. 2*8 = 16 bags.
Answer:
no
Step-by-step explanation:
sum of angles=74.5+87.1+23=184.6°≠180°
A = (B + b)xH : 2
A = (4.5+7.5) x 5 : 2
A = 12 x 5 : 2
A = 60 : 2
A = 30 in²
