One number is 4 less than 3 times another number. if their sum is 16, find the numbers.
what equations could be used to solve the problem if x represents a number?

One number is 11 and another is 5

Step-by-step explanation:

One number is 4 less than 3 times another number:

If we let "one number" be x, and

"another number" be y, we can write:

If their sum is 16:

This means if we add both the numbers, x & y, we get 16:

Now substituting equation 1 into equation 2, we can solve for y:

Now substituting y=5 into equation 1, we can solve for x:

Hence one number is 11 and another is 5

step-by-step explanation:

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
