Answer: it will take 5 hours to reach -1 °F.
Step-by-step explanation:
The temperature changes -4 degrees Fahrenheit per hour. This is a linear rate. The rate at which the temperature is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence(the starting point)
d represents the common difference.
n = x = the number of terms in the sequence(number of hours)
From the information given,
a = 0(at 1 pm, number of hours is 0)
d = - 4 degrees (it is decreasing)
Tn = -1 °F.
We want to determine the number of hours, x when Tn = -1 °F
Therefore,
- 1 = 0 + (x - 1)- 4
- 1 = - x + 4
x = 4 + 1
x = 5 hours
Answer:
x=70
Step-by-step explanation:
To solve this problem, you set up the equation 45+(2x-5)=180
Next, subtract 45 from 180 to get the equation 2x-5=135
After that, add 5 to 135 to get 2x=140
Divide 140 by 2 to get X=70
Answer:
x=27
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x−5)=3x+7
Step 1: Simplify both sides of the equation.
4(x−5)=3x+7
(4)(x)+(4)(−5)=3x+7(Distribute)
4x+−20=3x+7
4x−20=3x+7
Step 2: Subtract 3x from both sides.
4x−20−3x=3x+7−3x
x−20=7
Step 3: Add 20 to both sides.
x−20+20=7+20
x=27
Answer:
x=27
Answer:
The median is 2
Step-by-step explanation:
7 0 1 3 1 4 9 0
Arrange the numbers in order from smallest to largest
0 0 1 1 3 4 7 9
The median is the middle number
0 0 1 1 3 4 7 9
It is between 1 and 3, so average 1 and 3
(1+3)/2 = 4/2 =2
