Answer:
RT = 81
Step-by-step explanation:
RT = RS+ST
13y – 23 = ( 6y+2) + (3y+7)
13y – 23 = 9y +9
13y – 9y = 9+23
4y = 32
y = 32/ 4
y=8
RT= 13y – 23 = 13 (8) – 23 = 104 – 23 = 81
___o___o___
If you want RS , ST
RS = 6y +2 = 6(8)+2 = 48 +2=50
ST = 3y +7 = 3(8) +7 = 24 + 7 =31

Answer:
50,803,200 ways
Step-by-step explanation:
In this situation, since you should alternate girl-boy or boy-girl, the line-up can either start with a boy or a girl kicking which would yield one of the two following patterns:
BGBGBGBGBGBGBG or GBGBGBGBGBGBGB.
For each of those patterns, there are 7! ways to arrange all boys and 7! ways to arrange all girls. The number of ways that a line-up can be made for one round of kicking is:

There are 50,803,200 ways to set the line-up.
Answer:
x = 4,
x = -2
Step-by-step explanation:
( x - 4 ) ( x + 2 ) = 0
Find out when the equation is 0,
When x = 4,
substitute in 4 for x,
( 4 - 4 ) ( 4 + 2 ) = 0
(0) ( 6) = 0 (any number multiplied by 0 is 0).
When x = -2
Substitue in -2 for x,
( -2 - 4 ) ( -2 + 2 ) = 0
(-6) (0) = 0 (again, any number multiplied by 0 is 0).
Answer:
equation on circle: (x-h)^2 + (y-k)^2 =r^2
(x-3)^2 + (y+2)^2 = 841
Answer:
2,75,000 mL
Step-by-step explanation:
1 Litre = 1000 ml
So,
275 Litres = 275 x 1000 mL
= 2,75,000 mL
