Answer:

5t = 4b

Step-by-step explanation:

Here, we want to write a proportional relationship for b in terms of t

From the question, b represent the amount of candle burned away in a given time t hours

From what we have initially, 13 3/4 burnt in 11 hours

So in 1 hour, the amount burnt will be;

55/4/11 = 5/4

5/4 inches of candle burnt in 1 hour

5/4 inches = b/t

So b inches burnt in t hours

5/4 = b/t

5t = 4b

Levart [38]

Answer:

(-9, 3)

Step-by-step explanation:

25+{2[3+8-7(25/5)+11]}
Inessa05 [86]
Let's solve it step by step:
(we start with the innermost bracket:  (25/5). This is equal to 5. :

25+{2[3+8-7(25/5)+11]} =
25+{2[3+8-7(5)+11]} =

now, we can multiply 7 and 5, which is 35

25+{2[3+8-35+11]} =

Now we can add all the numbers in the square bracket, 3,8 (that's 11), then -35 (which is -24) then 11 - all together it's -13
3+8-35+11=22-35=-13

25+{2[-13]} =

Multiplying 2 and -13
25+{-26} =25-26, which is -1

the final answer is -1

Two classes have a total of 50 students. One class has 6 more students than the other. How may students are in the larger class
givi [52]
Subtract 6 from 50:
50-6 = 44
Divide 44 by 2:
44/2 = 22

add 6:

22+6 = 28

There is 22 in the smaller class and 28 in the larger class.
