Some of these, I don't know how to answer. I can only give the answers to the ones I do know how to do.
16. 24 plants can be watered with this can.
Equation & Answer:
134.4 ÷ 5.6 = 24
17. 32 miniature bottles can be made from the large bottle of ketchup.
Equation & Answer:
198.4 ÷ 6.2 = 32
20. -3 + -8 = -11
-3 + 8 = 5
3 + -8 = -5
-9 + 4 = -5
-6 + -1 = -7
-8 + 9 = 1
Negatives plus negatives:
When there are two negative numbers together and the equation has + sign in it, the + sign changes to be a - sign.
21. 42 + -56 = -14
22. -49 + -17 = -66
Hope this helped in some way,

Answer:
A, C
Step-by-step explanation:
The given ratio can be reduced by removing a factor of 2 from each element.
8 : 6 = 4 : 3 . . . . matches A
It can be put in other forms by multiplying each element by the same factor. Using a factor of 2 on the original ratio values, we get ...
8 : 6 = 16 : 12 . . matches C
__
Any ratio that doesn't reduce to the integer ratio 4 : 3 is not equivalent. The ratio with elements reversed (3:4) is not equivalent.
Answer:
Davide's age is 10.
L'età di Davide è 10.
Step-by-step explanation:
The average age of Aldo, Bruno, Carlo and Davide is 16 years.
I am going to say that:
x is Aldo's age.
y is Bruno's age.
z is Carlo's age.
w is Davide's age.
Average of the 4 is 16 years.
This means that:
If we do not consider Davide, the mean is 18. So
Replacing in the first equation:
Davide's age is 10.
L'età di Davide è 10.
49.95 Would be the Registration fee because it is a number by itself, 24.72m would be the monthly payment because it is being multiplied by m, m being months.
A number raised to the second power has an exponent above it. To the second power means the number multiplied by itself once.
x^2 is equal to (x)(x)
Hope this helps :)
