-16 because a negative times a positive is a negative
Answer: C
Step-by-step explanation: Cross multiply.
36/90 = x/100
3600/90 = 40
To get whether they are equal you have to cross multiply the numbers 18x16 and 48x3
48x3= 144
16x18= 288
144 is not equal to 288.
Therefore the rates aren’t equivalent.
-3/5 = -6/10
9/10 - 6/10 = 3/10
X=+-4
positive and negative 4
