Answer:
h = 6
Step-by-step explanation:
Given the 2 equations
- 3x + 4y = - 30 → (1)
9x + 5y = 39 → (2)
We require the value of the x- coordinate at the point of intersection, thus require to eliminate the y- term from the equations
Multiply (1) by 5 and (2) by - 4
- 15x + 20y = - 150 → (3)
- 36x - 20y = - 156 → (4)
Add (3) and (4) term by term thus eliminating y
- 51x = - 306 ( divide both sides by - 51 )
x = h = 6

Answer:
The error was they used the wrong inequality sign.
At most means: ≤
So, the correct equation is; 2x≤−24.
Given:
Number of boys = 5
Number of girls = 4
To find:
The number of ways in which 5 boys and 4 girls be arranged on a bench if there are no restrictions.
Solution:
We have, 5 boys and 4 girls.
Total number of boys and girls:
If there are no restrictions, then the total number of ways to arrange 9 persons is:
Therefore, the total number of ways to arrange 5 boys and 4 girls is 9! or 362880.
