-5x+13y=-7
5x+4y=24
add the equation to eliminate x:
13y+4y=-7+24
17y=17
solve for y:
17/17y=17/17
y=1
then plug in y into any equation to solve for x:
-5x+13y=-7, y=1
-5x+(13*1)=-7
-5x+13-13=-7-13
-5x=-20
-5/-5x=-20/-5
x=4 
the answers are x=4, y=1

The number of windows on each floor form an arithmetic sequence; 124 windows on the first floor, 116 windows on the second floor
zubka84 [21]

Answer:

Formula is 132 - 8n, and there are 52 windows on 10th floor.

Step-by-step explanation:

difference = 116-124 = -8  ( 8 less windows for every floor you go up)

the first fllor has 124 windows

Formula:

a_{1} = 124

a_{n} = 124 + (-8)(n - 1) = 132 - 8n

10th Floor:

a_{10} = 124 + (-8)(10 - 1) = 124 + (-8)(9) = 124 - 72 = 52  windows

If you walked 5 miles down a trail and then walked 2 1/4 miles back, how many miles away are you from your starting point?
lyudmila [28]
First lets figure out 2 and 1/4 as a decimal 
2 and 1/4 = 2.25 
So now we subtract 
5 - 2.25 = 2.75 
She is 2.75 miles away from her starting point

snow_tiger [21]

Answer:

21.74 ft

Step-by-step explanation:

We use Cosine because we are dealing with the Adj and Hyp

Cos 85 = x/20

x = 20 Cos 85

x = 1.74 feet away from the base of the wall.

Since the ladder is 20 foot long, the total distance will be 1.74 + 20 = 21.74 ft
