Answer:
1. x= 20/3 or 6.6666 repeating
2. x=3
3. a=39
Step-by-step explanation:
1. subtract 25 by 5 to get 20, then divide 20 by 3 to get x
2. divide 7 by 21 to get x
3. add 8 to 31 to get a equals 39
Answer:
2/8, 3/12 and 4/16
Step-by-step explaination:
All these fractions are equivalent to 1/4 as the numerator is a multiple of 1, the denominator is a multiple of 4, and the numerators are all a quarter of their respective denominators.
For this case we have the following expression:

We eliminate the parentheses:

We add similar terms:

Thus, we have a linear expression (the exponent of the variable term is 1).
The expression consists of two algebraic terms, so it is a binomial.
We have that algebraic terms are integers when they have no literal denominator.

Answer:
Step-by-step explanation:
hello :
(5y + 6)2 = 24 means : 5y+6 = √24 or 5y+6 = - √24
5y = - 6+√24 or : 5y = - 6-√24
y = (- 6+√24)/5 or y = (- 6-√24)/5
