8a - 4 = 25 + 6 (a - 8)
(distribute the 6)
8a - 4 = 25 + 6a - 48
(combine like terms 25 - 48)
8a - 4 = 6a - 23
( subtract 6a from both sides)
2a - 4 = -23
(add 4 to both sides)
2a = -19
(divide both sides by 2)
a = - 9.5
////CHECK/////
8 (-9.5) - 4 = 25 + 6 ( -9.5 -8)
(plug each side into a calculator)
-80 = -80
FINAL ANSWER:
a = -9.5
Answer: 2/3, 2:3, and 2 to 3
Explanation: there are three different ways to write ratios - using fractions, semi colons, and the word “to”
Answer: 3
Step-by-step explanation:

- Multiply the denominator of the fraction by the whole number.
- Add the product obtained and the numerator of the fraction.
- Write the sum obtained as the numerator and rewrite the original denominator of the fraction.
Then:

2. Multiply the numerators.
3. Multiply the denominator.
4. Reduce the fraction.
Then:

Yes, the answer of 25 is correct.
