Fish food is $3.50. An aquarium is $10.00. A filter system costs $9.95. Gravel and plants are $6.25. Mike has $30.00 to spend. H

Add all the prices together:

3.50 + 10.00 + 9.95 + 6.25 = 29.70

He has 30, so he had 30 - 29.70 = 0.30 left over for fish.

The two fish cost 4.50 + 4.50 = 9.00

He would need 9.00 - 0.30 = $8.70 more money

How do you write 0.8 recurring as a fraction?<br><br>please can i have an explanation aswell :)

monitta

Answer:

$\frac{8}{9}$

Step-by-step explanation:

we require 2 equations with the repeating digits placed after the decimal point.

let x = 0.888.. (1) ← multiply both sides by 10

10x = 8.888.. (2)

subtract (1) from (2) thus eliminating the repeating digits

9x = 8 ( divide both sides by 9 )

x = $\frac{8}{9}$

SSSSS [86.1K]

Answer:

x^2-x+5

Step-by-step explanation:

(f-g)(x)=f(x)-g(x)

= (x^2 + 3) - (x - 2) (Don’t forget the -1 multiplies to the x AND -2

= x^2 + 3 - x + 2

=x^2-x+5
