Put 8 into fraction form: 8/1
Put 1 2/5 into a mixed number: 1*5+2 as numerator and 5 as denominator (7/5)
Now multiply 8/1 by the reciprocal of 7/5, which is basically just the numerator and denominator flipped, so 5/7. This is like dividing.
8/1*5/7= 40/7
40/7= about 5.7.
So, your answer would be 5.7 batches, or 5 complete batches would be a better answer.

Step-by-step explanation:
V= lwh / 3 Write formula
V= 6*6*5 /3 Substitute
V=60
Step-by-step explanation:
x+y=84
x²=y+6
y+6+y=84
2y+6=84
2y=84-6
2y=78
y=39
x=84-39=45
I think you're having trouble because the equation you wrote for 8a has a slight typo.
The question says that the length is 9 less than twice the width. Your equation states the length is 9 times the width minus 2. So the length actually equals 2w – 9, meaning that w(2w – 9) = 180
Hope this helps! If you're still having trouble, let me know :)
Answer:

Step-by-step explanation:
I am going to say that:
Mary's amount is x.
Ashley's amount is y.
Oscar's amount is z.
Mary has at least 3 times the amount of cash that ashley and oscar have combined
Ashley's and Oscar's combined amount is y + z.
3 times this amount is 3(y + z).
At least 3 times means that z is equal or greater than 3(y + z).
So
