500 - 116 = 384 left to collect
384 divided into 3 weeks = 128
They must collect $128 per week in order to reach their goal of $500.
Answer:
Step-by-step explanation:
2/5 + x = 1
Multiply each term by 5
2 + 5x = 5
5x = 5 - 2
5x = 3
x = 3/5
If it has rational coefients and is a polygon
if a+bi is a root then a-bi is also a root
the roots are -4 and 2+i
so then 2-i must also be a root
if the rots of a poly are r1 and r2 then the factors are
f(x)=(x-r1)(x-r2)
roots are -4 and 2+i and 2-i
f(x)=(x-(-4))(x-(2+i))(x-(2-i))
f(x)=(x+4)(x-2-i)(x-2+i)
expand
f(x)=x³-11x+20

I asked Siri, "what is 3% of $648"
Answer:
The relation is 
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:
In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So
So
The relation is
