Step-by-step explanation:
(3x + 5y - 7r)/(z + t) = 9p
3x + 5y - 7r = 9p(z + t)
3x + 5y - 7r = 9pz + 9pt
3x = 9pz + 9pt - 5y + 7r
x = (9pz + 9pt -5y + 7r)/3
Answer:
The area of triangle is 120 cm².
Step-by-step explanation:
First, you have to calculate the height of the triangle using Pythogorem Theorem :
Let a = base = 10 cm,
Let b = height = h cm,
Let c = hypotenuse = 26 cm,
We have found out that the height is 24 cm. Next, we have to use the area of triangle formula :
Let base = 10cm,
Let height = 24cm,
Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx
Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5
Then plug K value into equation
Y=6.5X
Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.
Check:
X=50
Y=6.5x50
Y=320
