That is x = mean of x values , y = mean of y-values:-
= (3+2)2 , (5 + 2)/2
= (2.5, 3.5) answer.
22cm is the greatest
It should be greater than17(20-3)
and smaller than 23(20+3)
Answer:
V≈4.19ft³
Step-by-step explanation:
The volume of a sphere with a radius of 1 foot is 4.19ft³.
In order to find this:
V=4
3πr3=4
3·π·13≈4.18879ft³
Answer:
there
Step-by-step explanation:
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
Answer:
{x,y} = {1,1}
Step-by-step explanation:
[2] 6y = -14x + 20
[2] y = -7x/3 + 10/3
// Plug this in for variable y in equation [1]
[1] -10x - 6•(-7x/3+10/3) = -16
[1] 4x = 4
// Solve equation [1] for the variable x
[1] 4x = 4
[1] x = 1
// By now we know this much :
x = 1
y = -7x/3+10/3
// Use the x value to solve for y
y = -(7/3)(1)+10/3 = 1
Solution :
{x,y} = {1,1}
