Samantha mixes some amount of 25% sugar syrup with x grams of 10% sugar syrup.
kondor19780726 [428]

Answer:

40 grams

Step-by-step explanation:

y * 25% + x * 10% = 120 * 15%

x = 120 - y

(120-y) * 10% = x * 10%

y * 25% + (120 - y ) * 10% = 120 * 15%

0.25y + 12 - 0.1y = 18

0.15y = 6

y = 6 / 0.15

y = 40

Is 2.5 greater or less than 1,950
OverLord2011 [107]

Answer:

2.5 is less than 1,950.

Step-by-step explanation:

The decimal place is at the end of 1,950.

The decimal place is in the middle of the 2 and the 5.

Since 2.5 decimal place is closer, that means 2.5 has a lower value than 1,950.0.

You can subtract both values.

1,950 - 2.5 = 1,947.50, if it’s greater than 0, it means it has a lower value.

0 < 1,947.50.

Therefore, 2.5 < 1,950
