Answer:
A. X=-3
Step-by-step explanation:
16x-4+5x=-67
21x=-67+4
21x=-63
Divide through by 21
X=-3
B is the irrational. C & D are rational as they can be written in a ratio, aka a simple fraction. A is rational as it simplifies to +/-2, a whole number.
X = first integer
x + 1 = second consecutive integer
x + (x + 1) = 153..combine like terms
2x + 1 = 153
2x = 153 - 1
2x = 152
x = 152/2
x = 76
x + 1 = 76 + 1 = 77
so ur numbers are : 76 and 77...and u will find that when added equal 153.
To find the centroid, follow these steps: Step 1: Identify the coordinates of each vertex. Step 2: Add all the x values from the three vertices coordinates and divide by 3. Step 3: Add all the y values from the three vertices coordinates and divide by 3. Would be your answer
