Question 21727
Word problems are usually linguistic problems because once you figure out what is being asked the math is normally routine.  Let's try to rewrite the word problem as mathematical expressions.


x=mass of Pisa in tons
x+557=great pyramid
x-95=2695 (mass of Stonehenge)
2(x+557)=greater pyramid


Let's solve for x by using the equation x-95=2695:
x-95=2695
x=2695+95=2790


Now let's use our value for x to substitute and solve our problem.
2(x+557)=greater pyramid
2(2790+557)=greater pyramid
6694 tons = greater pyramid


Did we get it right?
