Answer:
Resulting equation will be 5x²=36.
Step-by-step explanation:
The given equations are 5y = 10x-----(1)
and x²+y²=36------(2)
Now we substitute the value of y from equation (1) into equation (2).
5y = 10x ⇒ y = 2x
Then equation (2) will be x²+(2x)²=36
x²+4x²=36 ⇒ 5x² = 36
So the equation after substitution of the value of y from equation 1 will be 5x² = 36.
Answer:
28
Step-by-step explanation:
First, find the ratio between the triangles. To do this, divide any side of the big triangle by corresponding side in the small triangle. I chose 35. So, 35/10 = 3.5. 3.5 is the ratio between the triangles. Multiply 3.5 by 8 to get 28, the length of the missing side. :)

Answer:
- V = 125 m³
- l = 7.5 cm
Step-by-step explanation:
You have not told us the sort of figure you're supposed to draw. If these are cuboids, then their drawings are substantially similar to the one shown in the attachment. Your figures may need to show the units on each of the dimensions.
1. A cube with edge lengths of 5 m has a volume of ...
V = s³
V = (5 m)³ = 125 m³
__
2. A cuboid with the given volume and other dimensions has a length of ...
V = lwh
675 cm³ = l(9 cm)(10 cm)
675 cm³/(90 cm²) = l = 7.5 cm . . . . . . . . divide by the coefficient of l
