Which sentence represents the inequality -2b + 7 > 27.5? !

The sentence that represents the inequality "-2b + 7 > 27.5" is "negative two times a number plus seven is greater than twenty-seven and five tenths"

Step-by-step explanation:

The goal of this exercise is to translate the inequality (in math language) to a colloquial statement.

Let's do the translation part by part.

The expression "2b" can be translated to "two times a number".

Then, the expression "-2b" can be translated to "negative two times a number".

The expression "-2b + 7", as we are adding 7 to the previous expression, can be translated to "negative two times a number plus 7".

The expression "-2b + 7 > ...", means that the expression at the left of the inequality is greater than the one at the right. Then, it can be translated as "negative two times a number plus 7 is greater than ...".

Finally, the expression "-2b + 7 > 27.5", can be translated as "negative two times a number plus seven is greater than twenty-seven and five tenths"

a. 12.5 kg

1 n = 1 kg·m/s²

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
