Answer:

9 < 24

Step-by-step explanation:

1.4 x 10 = 14

14 - 5 = 9

2.8 x 10 = 28

28 - 4 = 24

I am assuming this is an inequality.

Hope This Helps!

sasho [114]

Answer:

Step-by-step explanation:

$\frac{x^3}{a^3} +\frac{a^3}{x^3} =p\\\frac{x^3}{a^3} -\frac{a^3}{x^3} =q\\adding\\2\frac{x^3}{a^3} =p+q\\\frac{x^3}{a^3} =\frac{p+q}{2} \\substitute~in~first\\\frac{p+q}{2} +\frac{2}{p+q} =p\\\frac{(p+q)^2+4}{2(p+q)} =p\\(p+q)^2+4=2p(p+q)\\p^2+q^2+2pq+4-2p^2-2pq=0\\q^2-p^2+4=0\\q^2=p^2-4$

If the least value of n is 3, which inequality best shows all the possible values of n?

andrezito [222]

Answer:

1) B. n ≥ 3

2)A. 5x – 9

Step-by-step explanation:

If the least value of n is 3 then all the values of n must be greater or equal to 3

Thus the correct option is B :n ≥ 3

Given:

Milo's age is 9 years less than 5 times Pearl's age

Pearl's age is x years

5 times Pearl's age= 5x

then milo's age= 5x-9

so the correct option is A. 5x – 9 !
