10 less than 'x' may be represented algebraically as the quantity (x - 10) .
There's no way to calculate its numerical value without knowing the value of 'x'.
8/3 =2.6666
2.6666*2 =5.33333

Answer:
16.67%
Step-by-step explanation:
Total main course dishes sold during the day = 240
Burritos = 40
what percent of the main course dishes sold were burritos
Percentage of burritos sold = number of burritos sold / total number of dishes sold × 100
= 40/240 × 100
= 0.1666666666666 × 100
= 16.666666666666%
Approximately 16.67%
Answer:the width of the walkway is 5 feet
Step-by-step explanation:
Let x represent the width of the walkway.
The pool measures 10 ft by 20. If the walkway must have a uniform width around the entire pool, then the total length of the pool and the walkway would be 10 + x + x = 10 + 2x
The total width of the pool and the walkway would be 20 + x + x = 10 + 2x
The area covered by the pool and the cement walkway is 600 square feet. This means that
(10 + 2x)(20 + 2x) = 600
200 + 20x + 40x + 4x^2 = 600
4x^2 + 60x + 200 - 600 = 0
4x^2 + 60x - 400 = 0
Dividing through by 4, it becomes
x^2 + 15x - 100 = 0
x^2 + 20x - 5x - 100 = 0
x(x + 20) - 5(x + 20) = 0
(x - 5)(x + 20) = 0
x = 5 or x = - 20
The width cannot be negative. Therefore, the width of the walkway is 5 feet
