Answer:
22.5 grams of 10% cream is mixed with 37.5 grams of 2 % cream to prepare 60 grams of 5% cream.
Step-by-step explanation:
Let x grams of 10% cream is mixed with y grams of 2 % cream to prepare 60 grams of 5% cream.
So, x + y = 60 ............ (1) and
⇒ 10x + 2y = 300
⇒ 5x + y = 150 ............ (2)
Now, solving equations (1) and (2) we get,
4x = 150 - 60 = 90
⇒ x = 22.5 grams
So, y = 60 - x = 37.5 grams. (Answer)
Short answer:<span> Multiply by 100 for centimeters or 1000 for millimeters.</span>

Answer:
x = 4
Step-by-step explanation:
to find the zero let f(x) = 0 , that is
- 2x + 8 = 0 ( subtract 8 from both sides )
- 2x = - 8 ( divide both sides by - 2 )
x = 4
Answer:
you divide 4 into seven your answer would be 0.57142
the nearest thousanths is 1
the number beside 1 is 4 so you round off
4 but is less than five so you drop the 4 and remaining numbers and leave one as it is
Step-by-step explanation:
hope you understand good luck!
