Two numbers have a sum of 19 and a difference of 5. find the two numbers

Let "x" represent the first number and "y" represent the second number.

Set up a system of equations, solve one of the variables using any method (I will be using the elimination method), and then plug that solution into either equation to solve for the remaining variable.

x + y = 19

+ x - y = 5

2x = 24 added the equations to eliminate "y"

x = 12 divided both sides by 2

12 + y = 19 substituted "x = 12" into the first equation

y = 7 subtracted 12 from both sides

12 and 7

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c

answer: i believe its b. if you sound out the sentences that sounds wrong.
