If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:
(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4
The correct result would be x = - 7.
I think the a sewer are 71.333333 and 70 or if it's just 1 answer it's 70
Do you mean 45x95x-12? If so the answer is -51300
Adult+student=170 ----(1)
5adult+3student=650 ----(2)
(1)*3; 3adult+3student=510 ----(3)
(2)-(3); 2adult = 140
so adult = 70
then student = 170-70 = 100
answer: Tammy sold 70 adult tickets and 100 student tickets
So x and y
sum means add
difference means subtract
so we have
x+y=55 times (x-y)
use distributiver property which is
a(b-c)=ab-ac so
distribute 55(x-y)
55(x-y)=55x-55y
so we have
x+y=55x-55y
add 55y to boh sides
x+56y=55x
subtract x from both sides
56y=54x
divide both sides by 2
28y=27x
to find the ratio, switch the numbers around
ratio of y:x=27:28
therefor x is the greater number
ratio of larger to smaler is
28:27
