X = (w + y + z) / 4....multiply both sides by 4, cancelling the 4 on the right
4x = w + y + z ....subtract w and subtract z
4x - w - z = y....answer is A
Ok, I think I know what it is saying. I may not be correct but hopefully this gives a idea of a sort.....Im sorry.
The rotation of 90* reflected across the x-axis, so I would think that it is -O. 90(O,-O).
90(O,-O)greater than or equal to ( a units, b units).
L=1.5w
P=l+w
40=2.5 w
W=16
L=1.5(16) =24
Length is 24
Width is 16
According to the question,
Man needs to drink = 3 liters of water a day = 3000 ml
Women needs to drink = 2.2 liters of water a day = 2200 ml
Mr. Morrison drank = 880 ml
Mrs. Morrison drank = 700 ml
Total water needed to be drink by both men and women = 3000+2200 = 5200 ml
Total water drank by Mr. and Mrs. Morrison = 880+700 = 1580 ml
Water they both need to drink combined to meet the recommended amounts for the day = 5200 - 1580 = 3620ml
= 3.62 liters
Hope this helps!
