Let smaller no be x and bigger be y
- x+y=39--(1)
- 3x=y+81
- y=3x-81
- y=3(x-27)--(2)
Put it in eq(1)
- x+3(x-27)=39
- x+3x-81=39
- 4x=81+39
- 4x=120
- x=30
Now
The numbers are 9 and 30
Answer:
19.63
Step-by-step explanation:
To find the area of a circle you can use the formula πr². The diameter (10) is twice the radius. So, the radius is 5. 5² = 25. 25x π =25π. Then you must divide by 4 because the shape is 1/4 a circle.
Hope this helps ;)

Answer:
Step-by-step explanation:
(2nm⁻³) * 2m³n⁻³
First, focus on the coefficients, 2*2 = 4.
Now the n, n * n⁻³ = n⁻²
Now the m, m⁻³ * m³ = m⁰ = 1
Now multiply altogether, 4n⁻²(1) =
14-3(4n-1)=14-3*4n+3=14-12n+3=17-12n.
