Answer:
AOC = 124°
Step-by-step explanation:
Angle on a straight line is 180°, therefore, the sum of the three angles shown is 180;
This can be written like so:
(3x + 94) + (x + 30) + (2x - 4) = 180
This equation can be solved to find x:
6x + 120 = 180
6x = 180 - 120
6x = 60
x = 10
AOC = 3(10) + 94
= 30 + 94
= 124
First you must find the tenths place
7 .8 3 9
O T H Th
So, the 8 is in the tenths place. Now look at the number to it's right, 3.
Since 3 is less than 5, you just turn everything behind the 8, including the 3, into a zero, giving you 7.800 or 7.8
Answer:
2
Step-by-step explanation:
8/4 = 2
9x +5y= -45
put in standard form
y= mx+b
coefficient of x is the slope, b is the y intercpept
5y= -9x -45
y= -9/5 x -45
graphing will start at -45 on the y axis
from that point go down 9 to the right 5 for the slope continue and graph minimum
2 points to draw the line
hope this helps
