Subtract 6 to other side then we have 2x = 10 and we divide 2 we have 5 so x = 5
It will take her <u>144 minutes</u> in total because it takes her 48 minutes to read 1/3 of a book and 3 parts make 1/3 so 48 multiplied by 48 is 144
Answer:
You can buy 12 gallons of gas.
Step-by-step explanation:
I took 40 and 3.25, then divided them.
I got a very large ugly decimal. When simplified it is 12.
2x^2+20x = -38
2x^2 + 20x + 38 = 0
Divide both sides by 2.
x^2 + 10x + 19 = 0
The quadratic formula works very well here.
Let a = 1, b = 10 and c = 19
x = [-b +- sqrt{b^2 - 4ac}]/(2a)
Plug those values into the formula to find two answers for x.
One is negative and the other positive.
Good luck.
