What are the four consecutive numbers whose sum is 50?

1 answer:

4 0

X+x+1+x+2+x+3=50
4x+6=50/-6
4x=50-6=44
x=44:4=11
⇒The 1st number is 11, the 2nd is 12, the 3rd is 13 and the 4th is 14.

11+12+13+14=50

Set the equations equal to each other
Subtract x from both sides
Divide both sides by -4
x=-1/2

Answer:

$594.21

Step-by-step explanation:

Because 254.58 + 333.90+ 64.42= $622.87

and 10 off of $622.87 = $560.58

and 6% sales tax to $560.58 = $594.21

A road is made in such a way that the center of the road is higher off the ground than the sides of the road, in order to allow

Remark.

The problem is a bit indistinct. Where exactly are the two edges of the road? I'm going to say that they are the x intercepts, but that may not be true. Certainly it does not have to be true at all.

Graph.

A graph has been made for you. The maximum is marked for you. It is an approximation The actual height can be more accurately found.

Height

y = (-1/200)(x - 16)(x + 16)

y = (-1/200)*(x^2 - 256)

The maximum height for this graph only is when x = 0.Other graphs require completing the square.

y = (-1/200) * (-256)

y = 1.28 exactly. I thought the graph might be rounding the answer. It is not.
