3(x-1)=2x+5
3x-3=2x+5
3x-2x=3+5
x=8
Answer: h= 5.08
Step-by-step explanation:
In a parallelogram , the formula to find the area of the parallelogram is given by :-
, where b is the base and h is the height of the parallelogram.
Given : A=64 h=? b= 12.6
Substitute these values in the above formula , we get
![64=12.6\times h](https://tex.z-dn.net/?f=64%3D12.6%5Ctimes%20h)
Divide both sides by 12.6 , we get
![h=\dfrac{64}{12.6}=5.07936507937\approx5.08](https://tex.z-dn.net/?f=h%3D%5Cdfrac%7B64%7D%7B12.6%7D%3D5.07936507937%5Capprox5.08)
∴ The missing variable : h= 5.08

Answer:
Answer: Option D.
Step-by-step explanation:
Hey there!!
Here, To find the equation of a st.line passing through point (3,1) is :
![(y - 1) = m1(x - 3)](https://tex.z-dn.net/?f=%28y%20-%201%29%20%3D%20m1%28x%20-%203%29)
It is the first equation.
Given, Another equation is:
![y = \frac{2}{3} x + 1](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20x%20%2B%201)
It is 2nd equation.
Comparing the 2nd equation with y = mx+c we get,
Slope (m2) = 2/3.
As per the condition of parallel lines,
m1 = m2 = 2/3.
Putting, the value of m1 in equation 1st we get,
![(y - 1) = \frac{2}{3} (x - 3)](https://tex.z-dn.net/?f=%28y%20-%201%29%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20%28x%20-%203%29)
or, 3 (y-1) = 2(x-3)
or, 3y - 3 = 2x - 6
![y = \frac{2x - 6 + 3}{3}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B2x%20-%206%20%2B%203%7D%7B3%7D%20)
![y = \frac{2}{3} x - 1](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20x%20-%201)
Diving-3/3 = -1.
Therefore, y = 2/3 x - 1 is the required equation.
<em><u>Hope</u></em><em><u> </u></em><em><u>it</u></em><em><u> </u></em><em><u>helps</u></em><em><u>.</u></em>
Plotting the data to get the line of best fit, it is:
y<span> = 0.087</span>x<span> + 0.587
substitute x=2030-1980=50,
y = $4.94 is the price in 2030</span>
