One hour = 60 minutes
1260 words / 60 minutes = 21 words per meinute ( words/min)
Use y=1/2x and substitute into the second equation
x + 2(1/2x) = 8
x + x = 8
2x = 8
x = 4
then y = 1/2x = 1/2(4) = 2
180 IS in decimal form. 180.
I'll obviously need more information to help you with this !
stress = force/area = 100 N/ .5mm^2 = 200000000 newton/meter^2 (Pa)
Hmmmm...... your question didn't translate very well.....it is all garbled...
5x + 10x = 15 x sqrt (15x) = sqrt(15) = 3.872983 sqrt(x)
First 33 1/2 = 67/2 miles
and 1 1/4 = 5/4 gallons...you got that right
Miles per gallon is m/g 67/2 miles / 5/4 gallons = 67/2 x 4/5 = 268/10 === 26.8 mpg
Use the \({x}^{y}\) key....when you want to enter the exponent use open parenthesis '(' then the exponent then the +- key then close parenthesis ' ) '
You would have to tell us the prices and the amount of ounces or gallons to answer this ........ Sorry
