If -4m+20=50, then what is M equal to?

Answers

-4m+20=50
add 4m to both sides because I dislike negatives
20=50+4m
subtract 50 from both sides
-30=4m
divide both sides by 4
-30/4=m
-15/2=m
-7 and 1/2=m
-4m + 20 = 50
        -20     -20

50 - 20 = 30

-4m = 30

-4m/-4 = 30/-4

m = -7.5

The table shows the data of a random sample of fish that were collected from and later released into a lake.Type of Fish Bass Eel Gar
Number of Fish 92 56 52


How many gars are estimated to be present if a random sample of 1,000 fish is collected from the lake?
104
108
260
320

Answers

Answer:

Gars estimated to be present if a random sample of 1,000 fish is collected from the lake are:

260

Step-by-step explanation:

According to the given sample there was a total of 200(92+56+52) fish collected from a lake.

Of those, 52 were gar.

52/200 = 0.26 = 26%

i.e. 26% of the total fishes collected were jar

So, if 1000 fish are collected

26% of 1000 = (26)/(100)* 1000

                     = 260

i.e. 260 fishes were jar

Hence, gars estimated to be present if a random sample of 1,000 fish is collected from the lake are:

260
there was a total of 200 fish collected and released from the pond...of those, 52 were gar......52/200 = 0.26 = 26%

so if 1000 fish are collected....26% of 1000 = 0.26(1000) = 260 gar <==

Mrs. Anderson has 128 pencils left over at the end of the school year. She decides to keep half of them for the next year and divide the rest of the pencils evenly among her 16 students. How many pencils will each student receive? A. 9 B. 8 C. 18 D. 4

Answers

First we need to figure out what half of 128 is

128 ÷ 2 = 64

Now, we need to divide 64 by the amount of students she has (16)

64 ÷ 16 = 4

Therefore, each student will get 4 pencils meaning the answer is D
