Answer:
2:5, 2/5, 2 to 5
Step-by-step explanation:
The original price of the meal deal if they would have exactly enough money to buy two of the meal deal is $4
<h3>How to write and solve equation?</h3>
let
x = cost of the meal
Both = 2x - 3
- Jessica = 3/4x
- Callista = 1/2x
3/4x + 1/2x = 2x - 3
(3+2)x / 4 = 2x - 3
5/4x = 2x - 3
5/4x - 2x = - 3
(5-8)x/ 4 = -3
-3/4x = -3
x = -3 ÷ -3/4
= -3 × -4/3
= 12/3
x = $4

Whoops lol. The answer is 8b³ / c³. Screwed up my work :/
(2b/c)³
= (2bc⁻¹)³
= (2)³ * (b)³ * (c⁻¹)³
= 8b³c⁻³
= 8b³ / c⁻³
Step-by-step explanation:
Remember, you count frequencies. To find the relative frequency, divide the frequency by the total number of data values. To find the cumulative relative frequency, add all of the previous relative frequencies to the relative frequency for the current row.
