5 1/3 + (-4 1/6)+ (-2 1/2)

Mathematics
1 answer:
nlexa [21]3 years ago
6 0

Answer:

-\frac{4}{3}

Step-by-step explanation:

We are given that

5\frac{1}{3}+(-4\frac{1}{6})+(-2\frac{1}{2})

We have to find the value of given expression

\frac{5(3)+1}{3}-(\frac{4(6)+1}{6})-(\frac{2(2)+1}{2})

=\frac{15+1}{3}-\frac{24+1}{6}-\frac{4+1}{2}

=\frac{16}{3}-\frac{25}{6}-\frac{5}{2}

LCM(2,3,6)=6

=\frac{32-25-15}{6}

=\frac{32-40}{6}

=\frac{-8}{6}

=-\frac{4}{3}

Find the value of in the triangle shown below<br><br> 9, 7, and x around the triangle
enot [183]

Answer:

5.66 units

Step-by-step explanation:

A's per our discussion, x is a leg of right triangle.

Therefore, by Pythagoras theorem:

x =  \sqrt{ {9}^{2}  -  {7}^{2} }  \\  =  \sqrt{81 - 49}  \\  =  \sqrt{32}

x =  \sqrt{ {16}^{2}  -  {12}^{2} }  \\  =  \sqrt{256 - 144}  \\  =  \sqrt{112}

LMN≅PQR
tresset_1 [31]
<span>LMN≅PQR means that point L is equal to P, point M is equal to Q, and point N is equal to R. All lines are the same.

Point Q has an angle of 72, which means that point M also has an angle of 72.

Now you have two angles to find x. All interior angles of a triangle add up to 180, so you can set up the following equation to find x:

72 + 36 + x = 180

Subtract 36 from both sides.

72 + x = 144

Subtract 72 from both sides.

x = 72

The angle of point L, x, is 72.

Mike had 280 dollars to spend on 8 books.After buying them he had 16 dollars. How much did each book cost?
adell [148]
Well, you can't really determine the price of 1 book, but you can find out the average cost.

280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x

So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!
