Step-by-step explanation:
Let number be X
Therefore 2.5 of X = 0.75
X = 0.75/2.5
= 0.3
(5^-2)= (1/5^2)... (1/25) now cube that so it will be 1/15625. Hope that helps
Redued by 15%
orignal=100%
decrease by 15%=100%-15%=85%
find 85% of original
orignal=15 feet
85% of 15=0.85 times 15=12.75 feet
answer is B
I'm not exactly sure but I think it might be but if you were to do 4(x-7) that would be 15 because fifteen minutes seven equals eight and eight time four is thirty two Hope this helps!
Multiply 12 and 5 (by the same number) and add them to get whatever total ml of crayon wax is specified.
Ex: Total ml divided by 17, then find how many parts are red(12ml) and white(5ml)
