A number is doubled, then decreased by 13.7. The result is greater than 125.28. What is the smallest integer that satisfies this condition?

x > 69.49

Step-by-step explanation:

Step 1: Write out equation

2x - 13.7 > 125.28

Step 2: Add 13.7 to both sides

2x > 138.98

Step 3: Isolate x by dividing both sides by 2

x > 69.49

So x has to be greater than 70 in order to fit into the question context.

70

Step-by-step explanation:

Let x be the desired integer. Then 2x-13.7>125.28. Adding 13.7 to both sides gives 2x>138.98, and dividing both sides by 2 gives x>69.49. The smallest integer that is greater than 69.49 is .

Hope this helped! :)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
