Answer: Andre picked 252 lbs of apple
Step-by-step explanation:
Let x represent the number of pounds of apple that Jane picked.
Let y represent the number of pounds of apple that Andre picked.
Let z represent the number of pounds of apple that Maria picked.
Andre picks 3 times as many pounds as maria. This means that
y = 3z
z = y/3
Jane picks 2 times as many pounds as Andre. This means that
x = 2y
The total weight of the apples 840 ibs. This means that
x + y + z = 840 - - - - - - - - - -1
Substituting z = y/3 and x = 2y into equation 1, it becomes
2y + y + y/3 = 840
Cross multiplying by 3, it becomes
6y + 3y + y = 2520
10y = 2520
y = 2520/10 = 252
x = 2y = 2×252 = 504
z = y/3 = 252/3 = 84
Answer:
30 days(To the nearest tenth of a day)
Step-by-step explanation:
In this question, we are asked to give the number of days that a baby whale had grew to a size given the rate at which it grows per day.
We have been told that after the first day, it started growing to a point of 47.075 inch at a rate of 1.5 inch a day.
The number of days taken for this growth can be calculated by dividing the present size by the daily growth rate.
Mathematically, that is 47.075/15 = 31.38333
Now, we are told to convert this to the nearest tenth of a day. The value here should thus be 30.
7.5x - 100 > 79.86 + 5.8x
7.5x - 5.8x > 79.86 + 100
1.7x > 179.86
x > 179.86 / 1.7
x > 105.8
So think of it as division divide 3 by 2 and your anwser is what you hav
