X=2
So,
=4^2×2 -100
=4^4-100
=256-100
=56
Let, Number of Hours in Library = x
Number of Hours in babysitting = y
Inequality would be: x + y = 30 ;
& 8x + 6y ≥ 200
b) Solving: Multiply first equation by 6,
6x + 6y ≥ 180
Subtract it from 2nd equation,
2x ≥ 20
x ≥ 10
Now, substitute it in 1st equation,
10 + y = 30
y = 20
Your Answer would be (10, 20)
x - value is lesser or equal to 10, so it would move to left (decreasing direction)!
Hope this helps!

0.8=3.2*x
0.8/3.2=x
x=0.25 units
Real life scenarios of acute angles are:
- Sighting a ball from the top of a building at an angle of 55 degrees.
- The angle between two adjacent vanes of a fan that has 6 vanes
<h3>What are acute angles?</h3>
As a general rule, an acute angle, x is represented as: x < 90
This means that acute angles are less than 90 degrees.
<h3>The real life scenarios</h3>
The real life scenarios that involve acute angles are scenarios that whose measure of angle is less than 90 degrees.
Sample of the real life scenarios that satisfy the above definition are:
- Sighting a ball from the top of a building at an angle of 55 degrees.
- The angle between two adjacent vanes of a fan that has 6 vanes
