Answer
The missing value is -14
Step-by-step explanation:
First you make a ratio or proportion: -4/6=x/21
Then you cross multiply
-4x21 which is -84 then 6 times x which is 6x then the equation becomes 6x=-84
from 6x you divide which becomes x=-84/6 which is -14

What time between 6pm and 6:30 pm the hour and minutes hands be exactly 125* degree apart
Answer:
6:10pm
Step-by-step explanation:
At 6:00 the hands are 180° apart.
The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.
The minute hand moves 1/60 of the circle per minute = 6° per minute
Angle between the hands decreases by 6-0.5 = 5.5° per minute.
180 - 5.5t = 125
t = 125/5.5 = 10 minutes
The hands are 125° apart at t minutes after 6:00, or 6:10.
Please explain the answer. Thank you!

the length of the rectangle is 3 times the width. The perimeter is 65.6cm. find the width
Answer:
[tex]Let~the~length~of~rectangle~be~3x. Then,~its~breadth~will~be~x.\\Given~that,\\Perimeter~of~the~rectangle=65.6\\or, 2(3x+x) = 65.6 ~[Perimeter~of~rectangle=2(length+width)]\\or, 2(4x)=65.6\\or, 4x=32.8\\or, x = 8.2cm\\So,~the~width~of~the~rectangle~is~8.2cm.[/tex]

the expression 3(-2m + 5)-6(-4m-2) can be written in the form am + b what is the value of a + b in number form
Answer:
45
Step-by-step explanation:
The required simplified value of the given expression a + b is given as 45.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
3(-2m + 5)-6(-4m-2) = am + b
-6m + 15 +24m + 12 = am + b
18m + 27 = am + b
From the comparison,
a = 18 and b = 27
Now,
a + b = 18 + 27
= 45
Thus, the required simplified value of the given expression a + b is given as 45.

Step-by-step explanation:
x-4 = log (base3) of 6; add 4 to both sides
x= [log (base3) of (2*3) ] +4; split 6 to 2*3
x= [log (base 3) of 3 + log ( base 3) of 2] + 4; use rule log(ab) = log a+log b
x= log (base 3) of 2 + 1+ 4; use rule log (base a) of a = 1
x= log (base 3) of 2 + 5; put in the calculator
x≈5.63
