Answer:
x=4
Step-by-step explanation:
-x+4=2x-8
4=2x-(-x)-8
4=2x+x-8
4=3x-8
3x=4+8
3x=12
x=12/3
x=4
To find the growth rate of anything, you plug the numbers into this equation:
(present)-(past)/(past).
1292(present)-1200(past)/1200(past)= 23/300=.07
The hourly growth rate is 7%
Answer:
25 minutes...
Step-by-step explanation:
This is because if he can complete 12 math problems in 6 minutes when u simplify that u get 2 problems done per minute so that would make 50 problems done in 25 minutes
Answer:
500
Step-by-step explanation:
1.

and x+y=6
2. x^2+y^2 and x+y remind us of the formula:

substituting we get:

2xy=36-28
xy=8/2=4
3 Let's solve the system of equations i)x+y=6 and ii)xy=4
substitute y=4/x in (i):

multiply all sides by x:


complete the square:


or

or

so from x+y=6, y=6-x
case 1,

gives

case 2,

gives
