Two co-teachers, Daniel and Mathew, have to grade a set of math journals. Daniel grades 45% of the journals and Mathew grades 55% of them.
Mathew has to grade 121 journals. How many total journals have to be graded?

220

Step-by-step explanation:

55 percentage of x = 121

so X = 220

as simple as that

answer: the answer is 35%

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
