3 times a number (3x) plus 12 (+ 12) minus times the same number (- 5x) is 22.

HERE'S THE EQUATION:

 3x+12-5x=22

COMBINE LIKE TERMS (3x + -5x):

-2x +12 = 22

SUBTRACT 12 TO ISOLATE -2x:

-2x +12 = 22
       -12    -12
= -2x = 10

DIVIDE BY 2 TO ISOLATE X:

\frac{-2x}{-2} =  \frac{10}{-2}

FINAL ANSWER:
x = -5

The volume of a right rectangular prism is 573.3 cm³. The length of the right rectangular prism is 7.35 cm and the height is 16.
IgorLugansk [536]
The width of the right rectangular prism is 4.8. You multiply 7.35 by 16.25 and then you divide 573.3 by that answer. So, 573.3 ÷ 119.4375 = 4.8. Hope this helped

The probability that a student uses Smarthinking Online Tutoring on a regular basis is 0.31 . In a group of 21 students, what is
Ivenika [448]

Answer: 0.0241

Step-by-step explanation:

This is solved using the probability distribution formula for random variables where the combination formula for selection is used to determine the probability of these random variables occurring. This formula is denoted by:

P(X=r) = nCr × p^r × q^n-r

Where:

n = number of sampled variable which in this case = 21

r = variable outcome being determined which in this case = 5

p = probability of success of the variable which in this case = 0.31

q= 1- p = 1 - 0.31 = 0.69

P(X=5) = 21C5 × 0.31^5 × 0.69^16

P(X=5) = 0.0241
