Answer:
y = 0
Step-by-step explanation:
We assume you want to find y such that ...
Dividing the second equation by 2, we can write an expression for x.
x +2y = -2
x = -2y -2
Substituting this into the first equation gives ...
y = 3(-2y -2) +6
y = -6y -6 +6 . . . eliminate parentheses
7y = 0 . . . . . . . . . add 6y
y = 0 . . . . . . . . . . divide by 7
The value of y in the system of equations is 0.
1/8 into a decimal is 0.125.

Answer:
The number is 2.26
Step-by-step explanation:
Let The given numbers be x
Now according to question :
x : 18 = x² - 5
I.e x = 18 × ( x² - 5 )
or, x = 18 × x² - 90
or, 18 x² - x - 90 = 0
Or, From quadratic equation , the value of x
x = 
Or, x = 
Or, x = 
So, x = 
∴ x = 
= 2.26
Hence The number is 2.26 Answer

Answer:
c = 5.00w +3.10g
Step-by-step explanation:
Let w represent the number of car washes purchased, g represent the number of gallons of gas purchased, and c represent the total cost of the trip.
cost = (cost of car washes) + (cost of gas)
c = 5.00w + 3.10g
