Answer:

[See Below]

Step-by-step explanation:

\boxed{Hey~There!}

__________________________________________________________

\boxed{Solve~-3x

  • Rearrange the equation by subtracting what is to the right of the greater than sign (≤, ≥) from both sides of the inequality:

                 -3*x-(9)

  • Pull out like factors:  

                -3x - 9  =   -3 * (x + 3)

  • Divide both sides by -3:
  • Remember to flip the inequality sign:

                 

  • Subtract 3 from both sides:

                 x > -3

\boxed{The~answer~is: x > -3}

\boxed{The~answer~is: C}

In my fish tank, the ratio of red fish to blue fish is 1:5. There are 15 blue fish. How many red fish are there?
Doss [256]
The ratio of red fish to blue fish is 1:5

That means that for every one red fish you have, there are 5 blue fish. In this scenario, there are 15 blue fish.

What can you multiply 5 by to equal 15?
The answer is 3. Multiply each side of the ratio by 3

1x3=3 and 5x3=15

The new ratio is 3:15, meaning if there are 15 blue fish, there are 3 red ones

I hope that makes sense!

Hi there!

Since the sum of all angles in any triangle always adds up to 180 degrees, we can calculate this and solve for x.

4x + x + x = 180°
6x = 180
180 ÷ 6 = x
x = 30

So, now we know that x is 30°.

Hope this helps!

A red candle is 8 inches tall and burns at a rate of 710 inch per hour. a blue candle is 6 inches tall and burns at a rate of 15
Katarina [22]
Red candle:
Initial height  = 8 in
Burn rate = 710 in/h
After x hours, the height will be
h₁ = 8 - 710x

Blue candle:
Initial height = 6 in
Burn rate = 15 in/h
After x hours, the height will be
h₂ = 6 - 15x

When the two heights are equal, then
h₁ = h₂
8 - 710x = 6 - 15x
-695x = -2
x = 0.00288 hours

Answer:
The answer may take one of these forms:
0.003 hours, or
0.0029 hours, or
0.00288 hours.
