Answer:
Solutions:-5,0,9,6
Not solutions: 12.5,10
Explanation:
The inequality that was given is:
20 > 5 + 3x
First, group similar terms;
20 - 5 < 3x
15 < 3x
x = 5
Thus, the solutions are:-3.5, 5, 4 3/4, -15
The not solutions are:-10 2/3, 129,
Hope this helps! :)
7x + 15 = 38
7x = 38 - 15
7x = 23
x = 23/7 (twenty- three sevenths)
Step-by-step explanation:
the sum of all angles in a triangle is always (ALWAYS !) 180°.
180 = 31 + 35 + x = 66 + x
x = 180 - 66 = 114°
Answer:
y=90 degrees
x=51 degrees
Step-by-step explanation:
all right angles are 90 degrees
90+39=129
180-129=51
Total the amounts he was over and under:
-3 + 4 -2 = -1
Now add that to the total par:
36 - 1 = 35
His score was a 35
