Answer:
-4/9
Step-by-step explanation:
We first calculate the first bracket.
[2/3-(-4/9)]
= (2/3+4/9) (we cancel out the negatives)
= (6/9+4/9) (common denominator)
= 10/9
Then we convert -2 1/2 into an improper fraction.
-2 1/2
= -5/2
Finally we calculate the division by swapping the numerator and denominator of -5/2.
10/9 / -5/2
= 10/9 * -2/5
= -20/45
= -4/9 (simplify the terms)
Answer:
−2(3x+12y−5−17x−16y+4)
=(−2)(3x+12y+−5+−17x+−16y+4)
=(−2)(3x)+(−2)(12y)+(−2)(−5)+(−2)(−17x)+(−2)(−16y)+(−2)(4)
=−6x−24y+10+34x+32y−8
=28x+8y+2

Answer:
6.75
Step-by-step explanation:
9x0.75=6.75
You forgot to put how long the original stick is
A) <span>3x + </span><span>2.5y= 27
B) 5x – 2.5y = 5
</span>Adding A and B we get
8x = 32
x = 4
A) 3*4 + <span>2.5y= 27
</span>A) 12 + <span>2.5y= 27
</span>A) <span>2.5y= 15
y = 6
