Answer:
6s + 8c ≥ 900
Step-by-step explanation:
The library has <em>at least</em> 900 square feet available. It means <em>900 or more</em>.
If s is the number of study cubicles and c is the number of computer stations, the total space occupied by them is 6s+8c. That space is 900 or more square feet, so our inequality is 6s + 8c ≥ 900
Answer:
Step-by-step explanation:
A quadratic equation is given to us and we need to solve the equation using the quadratic formula . The given equation is ,
Open the brackets in RHS ,
Transpose all the terms to LHS ,
The general form of a quadratic equation is ax² + bx + c = 0 , and the roots of the equation by the Quadratic Formula ( Shreedhacharya's Formula ) is given by ,
Using the quadratic formula , we have ,
Simplify ,

Answer:
Step-by-step explanation:
Each of the triangles is similar, so we have ...
3/5 = (3+x)/20
x = 20(3/5) -3
x = 9
__
4/5 = (4+y)/20
y = 20(4/5) -4
y = 12
__
3/5 = (3 + x + u)/60
u = 60(3/5) -3 -9
u = 24
__
4/5 = (4 +y +v)/60
v = 60(4/5) -4 -12
v = 32
Answer:
x has a greater change
