The answer is D and B trust me 100%
Step-by-step explanation:
Start by writing your own expression.
x is the smaller number and x + 1 is the next number
x(x + 1) = 420
x^2 + x - 420 =0 ⇒ constant = -420
The answer to the question is 54 I think
Answer: y = 5.4
Step-by-step explanation: This is a proportional statement. So we can set up a system of proportions.
So we know when x is 5, y is 3. Thus, we can set up a proportion such that substituting will give .
Now, we know when x is 9, y is some unknown number. So we can set up the second proportion as .
Since 5/3 and 9/y are directly proportional, these 2 expressions are therefore equal. So we have .
Cross multiplying, we get .
Dividing by 5, we get
