The two numbers would be 548 & 213.
Answer:
option 3,
Step-by-step explanation:
The formula to find the volume of a sphere is
where r os the radius
given: diameter = 18in
radius = diameter / 2
radius = 18 / 2
r = 9in
Plug in radius:
cancel common factor: 3
Let me know if you have any questions !
Adding them up, we have 1/2+3/20+2/5+4/5. We can do a bit of guess and checking to see that 2, 5, and 20 go into 20. 20/2=10 and 20/5=4, so we multiply 1/2 by 10/10 and 2/5 and 4/5 by 4/4 to get 10/20+3/20+8/20+16/20= 37/20
The answer is the middle option. It is ideal to solve using substitution for x in this system of equations.
Answer:
x = -4/3 x =1/2
Step-by-step explanation:
6x^2 +5x - 4 = 0
6 has factors of 3 and 2 and 6 and 1
4 has factors of -4 and 1 and -2 and 2, and -1 and 4
We want +5 in the middle
3* -1 + 4*2 = 5
( 3x+4) ( 2x -1) =0
Using the zero product property
3x+4 =0 2x-1 =0
3x = -4 2x =1
x = -4/3 x =1/2
