2x + 4y = -14
x - 2y = 9
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]

At room temperature, water will condense to form liquid water.
1 mole of methane reacts with 2 moles of oxygen to form 1 mole of oxygen.
10 ml (0.445 moles) of methane will react with 20 ml (0.89 moles) of oxygen to form 10 ml (0.445 moles) of carbon dioxide.
Hence, the resulting mixture will contain 10 ml of unreacted methane and 10 ml of carbon dioxide.
The total volume of the mixture will be 20 ml.

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.

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.

Which inequality describes the graph?
Please help if you can. Thank you
Answer:
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
