Which number can each term of the equation be multiplied by to eliminate the fractions before solving? -3/4m-1/2=2+1/5mHELP ME
Answers
Answer 1
Answer:
-3/4m - 1/2 = 2 + 1/5m...to eliminate the fractions, u must multiply the equation by the common denominator....which in this case is 20. Resulting in : -15m - 10 = 40 + 4m
What are the next 2 terms in this sequence? -5,-2,1_,_,?
Answers
The common difference is 3 so add three to 1 and to the answer you get
If 19 more than 2 times a number is 23, what is the number?
Answers
2 is the unknown number.
Let x be the unknown number.
2x + 19 = 23 2x = 23 - 19 2x = 4 2x/2 = 4/2 x = 2
to check: 2(2) + 19 = 23 4 + 19 = 23 23 = 23
The volume of a rectangular box is (x3 - 7x2 - 9x + 63) cubic units. Determine the dimensions of the rectangular box by factoring the volume expression completely.
Answers
Hello, well done. As x^3-7x²-9x+63=(x-3)(x+3)(x-7) we must have x>3 and x>-3 and x>7 thus x>7
sin (2x) can be written like:sin (2x) = 2sin(x)cos(x) substituting this expresion in the original one:sin(2x) /(x*cos(x) =2sin(x)cos(x)/x*cos(x)=2sinx/x taking limits, and noticing that lim as x->0 of sinx/x=1:lim 2sinx/x=2*1=2x->0
You have 1/4 of a tank of gas and 10 dollars in your wallet. Gas is $2.50/gallon and your car holds 13 gallons. Explain how you would find out how many total gallons you will have in your car after you put in $10 worth of gas
Answers
1/4*13=3.25 gallons
2.50*4=10
3.25+4=7.25
The answer is 7.25 gallons
Could you prove this trignometry identity? It's sin x cot x =cos x
Answers
Cotx can also be written as cosx/sinx. So sinx × cosx/sinx = cosx.
