Answer:
The no. of traditional type birdhouses are 4 and the no. of lavish type birdhouses are 3.
Step-by-step explanation:
Let x be the no. of traditional type birdhouses
The more traditional type takes 4 pieces of wood and 2 hours to build.
One house requires wood = 4
x houses requires wood = 4x
One house requires time = 2 hours
x houses requires time = 2x
Let y be the no. of lavish type birdhouses
The more lavish type takes 10 pieces of wood and 7 hours to build.
One house requires wood = 10
y houses requires wood = 10y
One house requires time = 7 hours
y houses requires time = 7y
Now we are given that he has a total of 46 pieces of wood and 29 hours to work,
So, equations becomes :
Plot these equations on graph
---Blue line
---Green line
Refer the attached figure
The intersection point provides the solution
Intersection point : (4,3)
So, x = 4 and y = 3
Hence the no. of traditional type birdhouses are 4 and the no. of lavish type birdhouses are 3.
Answer:
n + 4 = 6
6
Step-by-step explanation:
Given problem:
4 more than one third of a number n is 6
Unknown:
The equation = ?
Solution of the number = ?
Solution:
let the number = n
So, 4 more than one third of a number;
One third of n = n
4 more;
n + 4
is 6;
n + 4 = 6 (equation of the expression)
Let us now solve the equation:
n + 4 = 6
n = 6 - 4
n = 2
n = 6
