Answer:
B
Step-by-step explanation:
We require 2 equations in 2 variables
let x be the number of salads sold and y the number of drinks sold, then the 2 equations are
x + y = 209 → (1)
6.5x + 2y = 836.5 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate y
- 2x - 2y = - 418 → (3)
Add (2) and (3) term by term
(6.5x - 2x) + (2y - 2y) = (836.5 - 418) ← simplify
4.5x = 418.5 ( divide both sides by 4.5 )
x = 93
The number of salads sold was 93
Answer:
12 300
Step-by-step explanation:
The way that I would do this, is first doing 7*300. That would result in 2100.
Next would be doing 7*12. Resulting in 84.
Finally you would add 2100 and 84 which is very simple just 2184.
If 300 looks like a tough number to multiply, just do 7*3 then add two 0's to the end.
The formula of a volume of a cone:
We have:
substitute:
Answer:
height = 6 cm
radius = 3 cm
S^2 = 16/36 ft^2
s = √(16/36 ft^2) = 4/6 ft
The side length of the square is 2/3 ft, or 8 inches.
