Answer:

composite

Step-by-step explanation:

27 can be factored into 1(27), 3(9), 9(3), and 27(1)

prime numbers can only be factored into 1(x) and x(1)

hope this helps

E = {x|x is a perfect square between 1 and 9} = {1,4
F = {x|x is an even number greater than or equal to 2 and less than 9}
D = {x|x is a whole number}

answer
D ∩ (E ∩ F) = 4

I need help on this problem! g(h+2/3)=1 for h

Tju [1.3M]

Answer:

$g(h + \frac{2}{3} ) = 1 \\ \\ gh + \frac{2}{3} g = 1 \\ \\ gh = 1 - \frac{2}{3} g \\ \\ h = (1 - \frac{2}{3} g ) \div g \\ \\ h = (1 - \frac{2}{3} g ) \times \frac{1}{g} \\ \\ h = \frac{1}{g} - \frac{2}{3}$

I hope I helped you^_^

1.3x - 10= 0.8x - 8 solve for x

OverLord2011 [107]

Answer:

x = 4

Step-by-step explanation:

1.3x - 10 = 0.8x - 8

Add 10 to both sides.

1.3x = 0.8x + 2

Subtract 0.8x from both sides.

0.5x = 2

Divide by 0.5.

x = 4.

Proof:

1.3x - 10 = 0.8x - 8

1.3(4) - 10 = 0.8(4) - 8

5.2 - 10 = 3.2 - 8

-4.8 = -4.8

Answer:

x>14

Step-by-step explanation:

X-3> 11

Add 3 to each side

X-3+3> 11+3

x > 14

The hole is open at 14 since it is greater than

( it would be closed if it were ≥) The line goes to the right since it is greater than
