Number of multiples of 7 up to 1337:

Number of multiples of 11 up to 1337:

Number of multiples of 77 up to 1337:

This means there are

distinct multiples of 7 *or* 11 up to 1337.
The sum of these multiples is

which can be computed using the well-known formula,

So you have
So 39 books and it must equal 70. So 39 + ___ = 70 or, to make it a bit simpler, 70 - 39 = ___. You should be able to do that.
Hey there!
x(y - 2) + xz
= 2(5 - 2) + 2(7)
= 2(3) + 2(7)
= 6 + 14
= 20
Therefore, your answer is: 20
Good luck on your assignment and enjoy your day!

Answer:
x ≈ 2.55
Step-by-step explanation:
Since the triangles are congruent then DE ≡ AB , that is
DE = AB
76x - 7 = x + 184 ( subtract x from both sides )
75x - 7 = 184 ( add 7 to both sides )
75x = 191 ( divide both sides by 75 )
x ≈ 2.55 ( to the nearest hundredth )
