A class is practicing their typing skills. They want to find out who is the most efficient typist. A 3-column table with 4 rows. Column 1 is labeled Name with entries James, Shanya, Tristan, Ebony. Column 2 is labeled number of words with entries 15, 120, 30, 100. Column 3 is labeled time (seconds) with entries 30, 40, 20, 50.

Find the unit rate for each person’s typing test in words per second.

0.5 words/second is the unit rate for James.

3 words/second is the unit rate for Shanya.

words/second is the unit rate for Tristan.

words/second is the unit rate for Ebony.
So,
is the fastest typist.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the answer will be

i believe the correct answer is b.
