Answer:
The number is 5.
Step-by-step explanation:
The product of 5 and 4 more than a number = 9 times the number
Let the number be x;
5(4 + x) = 9x
20 + 5x = 9x
4x = 20
x = 20/5
x = 5.
4 + 3 + 2 = 9
18/9 = 2
3 x 2 = 6
Answer = 6
Answer:
i think 9

Answer:
Step-by-step explanation:
Length = x
width = x - 7
height = x - 10
volume = 600 in^3
Volume = L * w * h
600 = x * (x - 7)*(x - 10)
600 = x * (x^2 - 17x + 70)
600 = x^3 - 17x^2 + 70x
x^3 - 17x^2 + 70x - 600 = 0
There is a genius somewhere that could solve this using algebra. The rest of us have 2 choices. We can graph it (see below) or we could use a program that solves it for us. I'll do both for you.
a = 1
b = - 17
c = 70
d = - 600
There is only 1 real solution: x = 15
L = 15
w = 8
h = 5
That has to be one of the ugliest graphs made. It does into the hundreds of thousands and it still looks like a straight line. Trust me. It's not.
