Anyone?
@Ms.Sue
#6, wrong
-4-5(x+8)
= -4 - 5x - 40
= -5x - 44
#7 wrong
3x+4(x-6)-3(x-7)
= 3x + 4x - 24 - 3x + 21
= 4x - 3
#8. 8 + 8 < -28 , the answers make no sense according to the question,
the statement itself is false
#9. wrong
R/15>-3
R > -45
you're batting 0/4, looks like some serious studying ahead.
Sure! Let's check your answers:
6. -4-5(x+8)
To simplify this expression, we'll distribute the 5 across the parentheses:
-4 - 5x - 40
Combining like terms, we get:
-44 - 5x
So, the correct answer is A) -5x - 44.
7. 3x+4(x-6)-3(x-7)
Again, we'll start by distributing the terms inside the parentheses:
3x + 4x - 24 - 3x + 21
Combining like terms, we get:
4x - 3x - 3x - 24 + 21
Simplifying further:
4x - 6
So, the correct answer is B) 4x - 3.
8. 8 + 8 < -28
Adding 8 and 8 gives us:
16 < -28
Since this statement is false, none of the answer choices are correct.
9. R/15 > -3
To solve this inequality, we'll multiply both sides by 15 to isolate R:
R > -3 * 15
Simplifying further:
R > -45
So, the correct answer is A) r > -45.
Great job on most of your answers! Just be careful with the last inequality - remember to reverse the direction of the inequality symbol when multiplying or dividing both sides by a negative number. Keep up the good work!
