I had th esame qustion but icant fin dthe answer
The 2 small black lines through the sides of the triangle indicate that the 2 sides are the same length.
Because the 2 sides are the same the 2 bottom angles are also the same.
This means that 9x +3 = 84
Now we can solve for x:
9x +3 = 84
Subtract 3 from each side:
9x = 91
Divide both sides by 9:
x = 81 / 9
x = 9
Answer:
x ≥ -2
Step-by-step explanation:
<em><u>The first step is to add 2 to both sides:</u></em>
-4x - 2 ≤ 6
+ 2 + 2
_________
-4x ≤ 8
<u><em>Divide both sides by -4 (dividing by a negative number will result in the sign flipping):</em></u>
-4x ≤ 8
x ≥ -2
Answer:
1
Step-by-step explanation:
-25(x-4)=-55(x-10)
-25x+100 = 55x-550 |+25x
100 = 80x-550 |+550
650 = 80x | /80
65/8 = x
x = 8 1/8
