Answer:
x= -1/3 or x= -3/3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x2+6x−1=−5x−4
Step 1: Subtract -5x-4 from both sides.
6x2+6x−1−(−5x−4)=−5x−4−(−5x−4)
6x2+11x+3=0
Step 2: Factor left side of equation.
(3x+1)(2x+3)=0
Step 3: Set factors equal to 0.
3x+1=0 or 2x+3=0
x= -1/3 or x= -3/3
To get this answer you would multiply 42 times 39%
Step-by-step explanation:
So, the equation to solve then is: 0.3 x=100
Solving for x, we get x=100 /0.3
or x, we get x=333.333333
This means, 100 is 30 % of 333.333333
Answer: 68.5°F and 76.5°F
Step-by-step explanation:
Given: The heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) .
According to the given absolute inequality equation, where x is the temperature of house
|x – 72.5| = 4
it gives x – 72.5 ≥ -4 and x – 72.5 ≤ 4
⇒ -4 ≤ x – 72.5 ≤ 4
Adding 72.5 on both the sides, we get
⇒ -4+72.5 ≤ x ≤ 4+72.5
⇒68.5 ≤ x ≤ 76.5
Thus the minimum temperature is 68.5° F and the maximum temperature is 76.5° F.
