Solve for x over the real numbers:
-5 + 1/5 + 3/x = 9/20
-5 + 1/5 + 3/x = 3/x - 24/5:
3/x - 24/5 = 9/20
Bring 3/x - 24/5 together using the common denominator 5 x:
-(3 (8 x - 5))/(5 x) = 9/20
Cross multiply:
-60 (8 x - 5) = 45 x
Expand out terms of the left hand side:
300 - 480 x = 45 x
Subtract 45 x + 300 from both sides:
-525 x = -300
Divide both sides by -525:
Answer: x = 4/7
Answer:
It should be x=4
Let me know if i'm right and sorry if im wrong!^^
Let Peter's hit be x and Alice's runs be y.
x = 2(y - 6) . . . (1)
x + y = 18 . . . (2)
Putting (1) into (2) gives,
2y - 12 + y = 18
3y = 18 + 12 = 30
y = 30/3 = 10
x = 2(10 - 6) = 2(4) = 8
Therefore, Peter hit 8 home runs and Alice hit 10 home runs.
Answer: the weight in kilograms is 9.76kg
Step-by-step explanation:
1 meter of length of rope = 800 g
12.2 meters of the rope= (12.2meters x 800g)/ 1 meter=9760grams
We know that 1000 g = 1kg
9760 grams = 9760/1000=9.76 kilograms
The answer for this one will be b
