Subtract (-3f - 4g + 9) - (2 - 6f + 5g).
Answers
Answer:
Step-by-step explanation:
Remove the brackets. Watch out for that minus sign. It affects all three terms in the right bracket.
(-3f - 4g + 9) - (2 - 6f + 5g)
-3f - 4g + 9 - 2 + 6f - 5g
+3f - 9g + 7 is your answer.
Answer:
3f−9g+7
Step-by-step explanation:
(−3f−4g+9)−(2−6f+5g)
To find the opposite of 2−6f+5g, find the opposite of each term.
−3f−4g+9−2−(−6f)−5g
The opposite of −6f is 6f.
−3f−4g+9−2+6f−5g
Subtract 2 from 9 to get 7.
−3f−4g+7+6f−5g
Combine −3f and 6f to get 3f.
3f−4g+7−5g
Combine −4g and −5g to get −9g.
3f−9g+7

- The local museum requires 2 adult
chaperones for every 15 students. How
many adults would be needed with
90 students?
Answers
Answer:
For 90 students, 12 adult chaperones are required.
Step-by-step explanation:
90 (students) divided by 15 gives us a proportion to multiple the amount of adults by.
90/15 = 6
Since there are 6 times as many students as the question provided, we will multiply the amount of adults in the question by 6.
2 x 6 = 12

Which fraction can be replaced with 1 2 when estimating with fractions? A. 10 12 B. 7 16 C. 2 9 D. 1 8
Answers
Answer:
B. 7/16
Step-by-step explanation:
The answer to this question is the option whose value is closest to 1/2.
We know that the fraction 1/2 is 0.5, now we have to get that fraction out of all these fractions that is closest to the value 0.5
10/12 = 0.833
7/16 = 0.43
2/9 = 0.222
1/8 = 0.125
The value closest to 0.5 is obviously 0.43 from the above. Therefore we can conclude that the fraction 7/16 is closets to 1/2 given these other fractions.

Jeremy is 12 4 5 years old. Carl is 1 1 6 years younger than Jeremy and Jane is 1 1 3 years younger than Carl. How old is Jane?
Answers
Answer: Jane is 10 9/30 years old
Step-by-step explanation:
Given that Jeremy is 12 4 /5 years old
Carl is 1 1/6 years younger than Jeremy which is why we would subtract giving us
=12 4/5 - 1 1/6
= 11 (24- 5)/30
= 11 19/30 years
and Jane is 1 1 3 years younger than Carl which is why we would subtract giving us
=11 19/30 - 1 1/3
= 10 ( 19 - 10)/ 30
=10 9/30 years
