Forty-eight 6th graders bring their lunch to school. This is thirty percent of the 6th-grade class. How many students are in the 6th grade? (number only to the nearest whole)

160 students in the 6th grade.

Step-by-step explanation:

There are 160 students in the 6th grade because if 48 students is 30 percent then 10 percent is 16.  Meaning that 100 percent would be 160.

Students l Percent

l

48         = l     30

16          = l     10

160        = l     160

^ Hope that makes sense! (tried my best to do a ratio table :/ )

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
