A number w increased by 4 is less than -16

"increased by 3" becomes: 2n+3 ... To solve, first subtract 3 and n from each side of the inequality to solve for n while keeping the inequality ... Any number less than −7 will make this inequality true

Step-by-step explanation:

my birthday is in 2 days

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
