answer:
Simplifying Y2 + -20X + -6y + -51 = 0
Reorder the terms: -51 + -20X + Y2 + -6y = 0
Solving -51 + -20X + Y2 + -6y = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '51' to each side of the equation. -51 + -20X + Y2 + 51 + -6y = 0 + 51
Reorder the terms: -51 + 51 + -20X + Y2 + -6y = 0 + 51 Combine like terms: -51 + 51 = 0 0 + -20X + Y2 + -6y = 0 + 51 -20X + Y2 + -6y = 0 + 51
Combine like terms: 0 + 51 = 51 -20X + Y2 + -6y = 51
Add '-1Y2' to each side of the equation. -20X + Y2 + -1Y2 + -6y = 51 + -1Y2
Combine like terms: Y2 + -1Y2 = 0 -20X + 0 + -6y = 51 + -1Y2 -20X + -6y = 51 + -1Y2 Add '6y' to each side of the equation. -20X + -6y + 6y = 51 + -1Y2 + 6y Combine like terms: -6y + 6y = 0 -20X + 0 = 51 + -1Y2 + 6y -20X = 51 + -1Y2 + 6y Divide each side by '-20'. X = -2.55 + 0.05Y2 + -0.3y Simplifying X = -2.55 + 0.05Y2 + -0.3y
Answer:
y = 1 , x = 3
Step-by-step explanation:
3x + y = 10
x = 2y + 1
3(2y + 1) + y = 10
6y + 3 + y = 10
7y = 7
y = 1
x = 2(1) + 1
x = 3
Answer: $42.75
Step-by-step explanation:
Given: A home improvement store rents it’s delivery truck for $19 for the first 75 minutes and $4.75 for each additional 1/4 hour.
Since, 1 hour = 60 minutes
1/4 hour = 
If a customer rented the truck at 11:10 am and returned the truck at 1:40 pm the same day, what would his rental cost be
Time taken = 150 minutes
Since charge for first 75 minutes is fixed and charge of $4.75 for each additional 1/4 hour (15 minutes) is given by
The additional charge =![\frac{(150-75)}{15}\times4.75=23.75/tex]The total his rental cost =[tex]19+23.75=$42.75](https://tex.z-dn.net/?f=%5Cfrac%7B%28150-75%29%7D%7B15%7D%5Ctimes4.75%3D23.75%2Ftex%5D%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%3Cstrong%3EThe%20total%20his%20rental%20cost%20%3D%3C%2Fstrong%3E%5Btex%5D19%2B23.75%3D%2442.75)
