Answer:
2x+30
Step-by-step explanation:
The perimeter of a rectangle is
P = 2(l+w)
The length is 2/3 x+10 and the width is 1/3x +5
P = 2(2/3x +10 + 1/3x +5)
Combine like terms
P = 2(2/3x + 1/3x +10+5)
= 2(x +15)
Distribute the 2
= 2x+30
The equation for the determination of the z-score is shown below.
z-score = (x - μ) / σ
where x is the value in which we need to determine the z-score, μ is the mean or the average, and σ is the standard deviation.
Substituting the known values,
z-score = (1,030.00 - 1,200) / 100 = -1.7
Therefore, the z-score of 1,030 is -1.7.
Answer:
f = 1
Step-by-step explanation:
-f + 2 + 4f = 8 - 3f
-f + 4f + 3f = 8 - 2
6f = 6
f = 6/6
f = 1

Answer:
3 - 12 = -9°C
So the temperature in the end of the days was -9°C
Answer:
y=x+2
Step-by-step explanation:
Given, m = 1
Eqn of st line is y = mx + c
y = 1*x + c
y= x + c ........eqn (i)
since, the line passes through the point (4,2)
4 = 2 + c
c = 4 - 2
c = 2
Now, Putting the value of c = 2 in eqn (i)
y = x + 2 is req eqn of line
