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:
A
Step-by-step explanation:
A) EA and ST
Because 1/2 ≠ 1/6.
We know that 1/6 < 1/2, so we can set up an equation to see how many copies are needed for them to be equal.
(1/6)x = 1/2
[(1/6)x] × 6 = [1/2] × 6
x = 6/2 = 3
This equation shows that 1/6 × 3 = 1/2, therefore we need 3 copies of 1/6 to equal 1 copy of 1/2.
