Step-by-step explanation:
we know,
sum of all angles on a straight line is 180°.
so according to it,
x + 2x + 3x = 180
6x = 180
x = 180/6 = 30
x = 30°
therefore, value of x is 30°.
HOPE THIS ANSWER HELPS YOU DEAR! TAKE CARE
The answer is A because if you subtract 100-23-58 you get 19 then you simplify it
50-2n
that is the expression
To answer this all we need to do is DIVIDE.
98515 ÷ 85 = <span>1159
CHECK OUR WORK
1159 </span>× 85 = 98515

So, we were right!! :)
So, there would be 1159 trees on each acre.
Hope I helped ya!!

Answer:
x = 3
y = 0
z = 8
Step-by-step explanation:
a) 3x + 3y - z = 1
b) z = 8
c) -x -3y + 2z = 13
a) 3x + 3y - 8 = 1 (substitution)
a) 3x + 3y = 9
c) - x - 3y + 2(8) = 13 (substitution)
c) -x - 3y + 16 = 13
c) -x - 3y = -3
(3x + 3y = 9) + (-x -3y = -3)
= 2x = 6
x = 3
a) 3(3) + 3y - 8 = 1
9 + 3y - 8 = 1
y = (1 -9 + 8)/3
y = 0
