Answer:
19, 2
Step-by-step explanation:
let the 2 numbers be x and y with x > y , then
x + y = 21 → (1)
x - y = 17 → (2)
Add the 2 equations term by term to eliminate y , that is
2x = 38 ( divide both sides by 2 )
x = 19
substitute x = 19 into (1) for value of y
19 + y = 21 ( subtract 19 from both sides )
y = 2
The 2 numbers are 19 and 2
Answer:
for number 8 it B and for number 9 its D
Step-by-step explanation:
Hey there! :)
The formula for finding volume of a cone : ( π · r² · h ) ÷ 3
Radius = 6
6² = 6 · 6 = 36
Height = 8
π = 3.14
Multiply:
8 × 6 × 3.14 = 150.72
The volume is 150.72 cubic meters
Hope this helps :)
Answer:
19/12 or 1/7/12
Step-by-step explanation:
- find what is common in both denominators. in this case 12 can be divisible.
- 3x3/4x3 + 5x2/6x2
- 9/12+10/12=19/12=1/7/12
I believe it to be 1 over 3 as 1 as the numerator and 3 as the denominator
