HELP PLEASEDory and Nemo go to Taco Bell for lunch. Dory orders three soft tacos and three double deckers for $11.25. Nemo pays $10.00 for four soft tacos and two Double Deckers. Write a system of equations that represents the lunch orders for Dory and Nemo. Use x to represent soft tacos and y to represent Double Deckers.

Answers

Answer 1
Answer: x = soft tacos
y = double deckers

Dory:
3x + 3y = 11.25 

Nemo:
4x + 2y = 10.00

---Now to solve for x and y---
---We find LCM of either x or y then make them cancel each other---
Dory multiply by 2:
6x + 6y = 22.50

Nemo multiply by 3:
12x + 6y = 30.00

--eliminate y--- 
Nemo subtract Dory:
6x = 7.50
Therefore x = 7.50 ÷ 6 = 1.25
---Now substitute x = 1.25 in either equation.---

Dory:
3.75 + 3y = 11.25
Therefore 3y = 11.25 - 3.75
therefore 3y = 7.50
there fore y = 2.50

y = 2.50 , x = 1.25

Sorry, that this is so long, I hope you understand. This is called simultaneous equations, you can read up on it.

Step-by-step explanation:

Jim cash the paycheck and went shopping he spent 3/8 of it on a mower 2/5 of it on at chainsaw and 180 On Tools if he has 270 left how much was his paycheck worth

Answers

Declaration

Let the original amount of the paycheck be x

Equation

Paycheck - cost of mower - cost of chainsaw - 180 = 270

x - [(3/8)x + (2/5)x + 180] =  270

Solve

Change 3/8 and 2/5 to a common denominator and add.

3*5/8*5 + 2*8/5*8 = 15/40 + 16/30 = 31/40

x - [(31/40)x + 180] = 270                 Remove the outer brackets

x - (31/40)x - 180 = 270                    Evaluate the "x"s

40/40x - 31/40x - 180 = 270        

9x/40 - 180 = 270                          Add 180 to both sides

9x/40 = 180 + 270

9x/40 = 450                                  Multiply by 40

9x = 18000                                    Divide by 9

x = 18000/9

x = 2000

His paycheck was 2000 dollars.
