time taken by a worker= 1/3 hours
time taken by the new worker= 1/5 hours
time taken to complete the work if they work together
= 1/3 + 1/5
= 5+3/15
=8/15
=15/8 hours
A rose costs $2.5 and a carnation costs $3.
Step-by-step explanation:
Let,
Roses = x
Carnations = y
According to given statement;
8x+10y=50 Eqn 1
6x+12y=51 Eqn 2
Multiplying Eqn 1 by 6;

Multiplying Eqn 2 by 8;

Subtracting Eqn 3 from Eqn 4;

Dividing both sides by 36;

Putting y=3 in Eqn 3;

Dividing both sides by 48;

A rose costs $2.5 and a carnation costs $3.

Answer: -10x + 1y = 2
Step-by-step explanation:
The standard formula says that Ax + By = C where A is the coefficient of the x variable, B is the coefficient of the y variable, and C is the constant value.
y = 10x + 2 Subtract 10x from both sides of the equation .
-10x -10x
-10x + 1y = 2
