Miss Crowe best inmates at 6 math problems are completed for every 13.5 minutes they are online about how many problems would be
Soloha48 [4]
All we need to do for this problem is multiply and divide. Let’s find the problems-per-minute!

6/13.5 = 0.44

Now we multiply this by 44 minutes to get the final answer.

0.44 * 44 ≈ 19 [you can’t solve 0.36 of a problem]

And there you have it! The inmates can solve 19 problems in 44 minutes online.

Hey, I'm not sure if I'm wrong or not but wouldn't the answer be c divided by pi? or c/pi
dedylja [7]

Answer:

You are correct

It is C divided by PI

Answer:

\boxed{\sf -2}

Step-by-step explanation:

\sf Evaluate \:  -  {x}^{2}  - 4x - 6 \:  where \:  x =  - 2: \\  \sf \implies  -  {x}^{2}  - 4x - 6 =  -  {( - 2)}^{2}  - 4( - 2) - 6 \\  \\  \sf  {( - 2)}^{2}  = 4 :  \\  \sf \implies  -  \boxed{ \sf 4} - 4( - 2) - 6 \\  \\  \sf - 4( - 2) = 8 :  \\  \sf \implies  - 4 +  \boxed{ \sf 8} - 6 \\  \\  \sf  - 4 + 8 - 6 = 8 - (4 + 6) :  \\  \sf \implies 8 - (4 + 6) \\  \\  \sf 4 + 6 = 10 :  \\  \sf \implies 8 -  \boxed{ \sf 10} \\   \\  \sf \implies -  2

Ira Lisetskai [31]

Answer:

x = 48

Step-by-step explanation:

The trick here is to get everything into the numerator. To do this, we multiply everything by 4*3.

\frac{1}{4}x=\frac{1}{3} x+-4\\3x=4x-48\\48=4x-3x\\x=48
