If there is 20 pencils there will be 5 erasers 20:5
Answer: x = - 2√5, √5/3
Step-by-step explantion
3 √ 5 x 2 + 25 x − 10 √ 5 = 0 35x2+25x−105=0
⇒ 3√5x2 + 30x – 5x – 10√5 = 0
⇒ 3√5x(x + 2√5) – 5(x + 2√5) = 0
⇒ (x + 2√5)(3√5x – 5) = 0
x = - 2√5, √5/3
Answer:
(3/2)power 3 = 27/8 =3.375
Answer:
The difference between the high and low temperature in the thermometer is 23°F.
Step-by-step explanation:
Given information: Highest temperature = 20°F and the lowest temperature = -3°F.
We need to find the difference between the high and low temperature in the thermometer.
Difference between the high and low temperature is
Difference = Highest temperature - Lowest temperature
Difference = 20°F - (-3°F)
Difference = 20°F + 3°F
Difference = 23°F
Therefore the difference between the high and low temperature in the thermometer is 23°F.
X = 5
Condense the left side.
log x(3x-13)=1
Put a base 10 on each side to clear the log.
x(3x-13)=10
3x^2-13x-10=0
Factoring you get x=5 and x=-2/3. The domain for log is x>0 so the -2/3 is an extraneous solution.
