The sum of two consecutive Integers are 199. Find the Integers

Yanka [14]

Answer:

99 and 100.

Step-by-step explanation:

Let's say the lower number is x. This means that the bigger number would be x+1

x+x+1=199

Simplify

2x+1=199

Subtract 1 on each side of the equation to isolate 2x:

2x=198

Divide

x=99

Let's put this to the test! The lower number(x) is 99, and the bigger number(x+1) would be 100. The total is 199.

Happy learning!

Ede4ka [16]

Answer:

x<4

Step-by-step explanation:

$x + 1 > -5( 7-2x) \\\\\mathrm{Expand\:}-5\left(7-2x\right):\quad -35+10x\\x+1>-35+10x\\\\\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}\\x+1-1>-35+10x-1\\\\Simplify\\x>10x-36\\\\\mathrm{Subtract\:}10x\mathrm{\:from\:both\:sides}\\x-10x>10x-36-10x\\Simplify\\-9x>-36\\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}\\\left(-9x\right)\left(-1\right)$

$\mathrm{Divide\:both\:sides\:by\:}9\\\frac{9x}{9}$
