Answer:
B. 3x+15 / 4x+10
Step-by-step explanation:
X
-> multiply by the reciprocal
X
-> reduce the expression
X
-> multiply the fractions
-> remove parenthesis

Answer:
1.2
Step-by-step explanation:
1. Set up the long division.
2. Calculate 3 ÷ 3, which is 1.
3. Bring down 6, so that 6 is large enough to be divided by 3.
4. Calculate 6 ÷ 3, which is 2.
5. Therefore, 3.6 ÷ 3 = 1.2
Hope this helps :)
1) yes
2) x=-4,y=-7
3) x= -3, y=4
4) x= -1, y=2
5) x= -5, y=-8
For this case we first write the equation of which we will use:
I (db) = 10log (l / l)
We substitute the value of l.
We have then:
l = 10 ^ 8lo
Substituting in the given equation:
I (db) = 10log ((10 ^ 8lo) / lo)
Rewriting:
I (db) = 10 * log (10 ^ 8)
I (db) = 80
Answer:
I (db) = 80
