Add all the x up and then you add all the ones that doesn't have an x then divide those 2 together.
×=46
54
Answer:
45, 36
Step-by-step explanation:
let x y minutes be the time for pipes to fill the tank, let n be the water needed to fill the tank.
x-y=9
(n/x)*20+(n/y)*20=n
n is removed by dividing the 2nd equation by n
here u get:
(1/x+1/y)*20=1
you sub x=9+y into the above equation
1/y+1/(9+y)=1/20
((9+y)+(y))*20=(9+y)(y)
180+40y=9y+y2
y2-31y-180=0
then use the quadratic formula and u will find y=36 or -5
-5 is rejected because it is negative
x=36+9=45
therefore it is 36 mins and 45 mins
Answer:
3x+12
Step-by-step explanation:
You need to do 3 times x which equals 3x and then do 3 times 4 and get 12 so it ends up as 3x+12
hope this helps
stay safe:)))

Answer:
2268 grams or 2 kg 268 g
Step-by-step explanation:
<u>How to convert Pounds to Grams</u>
1 pound (lb) is equal to 453.59237 grams (g).
1 lb = 453.59237 g
The mass m in grams (g) is equal to the mass m in pounds (lb) times 453.59237:
m(g) = m(lb) × 453.59237
In this case,
Convert 5 lb to grams:
2267.96 approximately convert to nearest thousands.
m(g) = 5 lb × 453.59237 = 2268 g or 2 kg 268 g
Answer:
30:16-15:8 That is simplified and I divided it by two.
