Answer:
3x+9 < - 42
Step-by-step explanation:
Simplemente necesitas restar tres de siete y dejar tu denominador como 4. Tu respuesta es 4/4, que es lo mismo que 1.
No because you would not be able to divide them by a number and get the same answer so no they are not proportional
Answer:
(0.00243)^-2/5 x (0.0009)^1/2
= (243/100000)^-2/5 x (9/10000)^(1/2)
= ((3/10)^5)^-2/5 x ((3/100)^2)^(1/2)
= (3/10)^-2 x (3/100)
=1/(3/10)^2 x (3/100)
= (100/9) x (3/100)
= (1/3)
Hope this helps!
