Answer:
Let's define the high temperature as T.
We know that:
"four times T, was more than 2*T plus 66°C"
(i assume that the temperature is in °C)
We can write this inequality as:
4*T > 2*T + 66°C
Now we just need to solve this for T.
subtracting 2*T in both sides, we get:
4*T - 2*T > 2*T + 66°C - 2*T
2*T > 66°C
Now we can divide both sides by 2:
2*T/2 > 66°C/2
T > 33°C
So T was larger than 33°C
Notice that T = 33°C is not a solution of the inequality, then we should use the symbol ( for the set notation.
Then the range of possible temperatures is:
(33°C, ...)
Where we do not have an upper limit, so we could write this as:
(33°C, ∞°C)
(ignoring the fact that ∞°C is something impossible because it means infinite energy, but for the given problem it works)
Answer:
a=36
Step-by-step explanation:
because look 0a=a
0a=36
a=36
Answer:
Excluded Value : <u>7</u> and <u>2</u>
Step-by-step explanation:
hello :
the excluded value when : x²-9x+14=0
means : (x-2)(x-7)=0 x-2=0 or x-7=0 so : x=2 or x=7
Excluded Value : <u>7</u> and <u>2</u>
