Answer:

3

Step-by-step explanation:

Lannister checks out 6 sets of book

Each set had the same number of books

She reads 7 books and has 11 more to go

Therefore the number of books in each set can be calculated as follows

= 11+7

= 18

18/6

= 3

Hence there are 3 books in each set

Which graph is the solution to this system y-4x=-1y+x=4
natali 33 [55]

First, let's find the x and y intercepts

In the first equation

y - 4x = -1

Put x =0

y= - 1

(0, -1)

Put y=0 and the n solve for x

0 - 4x = -1

-4x = -1

x=0.25

(0.25 , 0)

The points for the first equation is (0, -1 ) and (0.25, 0)

Next is to find the intercts for the second equation

y + x = 4

put x=0

y = 4

(0, 4)

Put y =0

0 + x = 4

x = 4

( 4, 0)

The points for the second equation are;

(0, 4) and (4, 0)

Below is the graph

lmk if this is incorrect, i'm not quit sure if it is or not. if i'm wrong, i'm so sorry!!

What is the length of the hypotenuse? If necessary, round to the nearest tenth.
N76 [4]

Answer:

7 feet

Step-by-step explanation:

Pythagorean theorem

sqrt(4.5^2 + 5.3^2) = hypotenuse

sqrt(48.34) = hypotenuse

6.95269732 = hypotenuse

round to nearest tenth

7 feet = the length of the hypotenuse
