The sum is 18ft because 9in + 3in is 12in which is a foot. Then 12+1+5= 18ft

We already know that 1 ft= 12 in.

5 ft 9 in= 5 ft* (12 in/1 ft)+ 9 in= 69 in

12 ft 3 in= 12 ft* (12 in/1 ft)+ 3 in= 147 in

5 ft 9 in+ 12 ft 3 in= 69 in+ 147 in= 216 in

The final answer is 216 in.

Hope this would help~

Solve this system using elimination (20 POINTS)<br> 4x-7y=3<br> x-7y=-15
stiv31 [10]

Answer:

x = 6, y =3

Step-by-step explanation:

4x-7y=3

x-7y=-15

Multiply the first equation by -1

-4x+7y=-3

Then add this to the second equation to eliminate y

-4x+7y=-3

x-7y=-15

------------------

-3x +0y = -18

-3x = -18

Divide by -3

-3x/-3 = -18/-3

x = 6

Now find y

x -7y = -15

6 -7y = -15

Subtract 6 from each side

6-7y-6 = -15-6

-7y = -21

Divide by -7

-7y/-7 = -21/-7

y =3
