</u>
Step-by-step explanation:
<u>Step 1: Define</u>
3 - 4r ≥ 15
<u>Step 2: Solve for </u><em><u>r</u></em>
- [Subtraction Property of Equality] Subtract 3 on both sides: -4r ≥ 12
- [Division Property of Equality] Divide -4 on both sides: r ≤ -3
<u>Step 3: Compare</u>
- Substitute in <em>r</em>: -3 ≤ -3
This is true. -3 is less than <em>or equal to</em> -3.
Answer:

Step-by-step explanation:
This is an arithmetic sequence:

where d is the common difference and n is the index of any given term.
For the given sequence, the common difference is -1:

Knowing both the common difference and the first term, you can write the equation for this sequence:

Then you can use that equation to find the 75th term:

Answer:
x=-3
Step-by-step explanation:
follow the PEMDAS method then see if the 2 equation equal each other after plugging in the x.
Answer:
2
Step-by-step explanation:
10 friends each served 400 ml of lemonade consumes 400 x 10 = 4000 ml = 4 l of lemonade in total
Pitcher size is 2 l therefore 4 / 2 = 2 pitchers are required assuming no losses.
