As you know the answer already I don't think you need any further explanation :)
Answer:
96 inches
Step-by-step explanation:
We can write a proportion to solve
60 inches x inches
--------------- = -------------
5 ft 8 ft
Using cross products
60 *8 = 5x
480 = 5x
Divide by 5
480/5 = 5x/5
96 = x
96 inches
The answer to the question is d
For elimination, multiply one whole equation by negative one (-1), then add or subtract according to your signs. After that, it will be a one-step equation.
3x + 4y = 19 3x + 4y = 19 3x + 4y = 19 -2y = -14 y = 7
3x + 6y = 33 -1 (3x + 6y = 33) -3x - 6y = -33 -14 / -2
Then you would go back and substitute the value of (y) back into either equation and then solve for the remaining variable (x). Finally, use both values to make an ordered pair.
3x + 4y = 19 3x = -9 x = -3 (-3 , 7)
3x + 4(7) = 19 (-9 / 3)
3x + 28 = 19
Good Luck
