The Best Option Would Be D Because British Museum-Egyptian Pyramids Would Be Helpful, But National Geographic:Egyptian Pyramids, Facts, Photos, And Diagrams Has That And More. C I Wouldn't Find Very Helpful, Because It's Just Focused On Pyramids, And B Is Totally Out Of The Picture. Hope That Helps!
C? Least useful information, and includes an opinion, both uncomforting and personal.
Answer:
40.25
Explanation:
2(2x - 5 - 4) = 160 -17
first we do the first half on the left
2 × 2x = 4x
2 × -5 = -10
2 × -4 = -8
then the right
160 - 17 = 143
next is
4x - 10 - 8 = 143
we add 10 and 8, which equals - 18
4x - 18 = 143
after that we transfer the -18 to the other side to 143
4x - 18 = 143
+ 18 = +18
4x = 161
then we divide 4 on both sides
4x/4 = 161/4
x = 40.25 or 40.3 if you have to round up
Answer:
2H2O
Explanation:
Given that,
H2SO4 2NaOH → Na2SO4
We know that,
The number of atoms of the reactant and the number of atoms of the product is equal in the reaction.
Therefore,
H2SO4 2NaOH → Na2SO4+2H2O
Hence, the additional product balances the reaction is 2H2O
