The table shows the average amount of money the boys and girls in zina's class spent on their science fair projects. zina spent at most $2 more than the average amount spent by the girls in her class. part a: let z represent the amount of money zina spent. write the appropriate numbers and operations in the boxes to create an inequality of the situation. part b: what is the greatest amount that zina could have spent?

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
