Answer:
<h2>x = -2 (verified by algebra) ✅</h2>
Step-by-step explanation:
Since we are given the value of y, we can replace it with 5x + 7.
We now have: 3x + 5x + 7 = -9
We can now simplify by adding 3x and 5x to get 8x.
8x + 7 = -9
We can subtract 7
8x = -16
And now, we divide by 8
x = -2
We can check to make sure we are correct
3(-2) + 5 (-2) + 7 = -9
-6 + -10 + 7 = -9
-9 = -9 ✅
Answer:
∠ABC = 60°
Step-by-step explanation:
All angles in equilateral triangles are equal.
all angles in triangles added together = 180°
180°/3 = 60°
All angles in equilateral triangles are equal to 60°.
Step-by-step explanation:
if we simply add 1 to numerator and denominator (top and bottom of the fraction), we get a fraction that is bigger than the original fraction and smaller than the fraction that added 2 to numerator and denominator.
so, my choice would be
4/5
5/6
6/7
7/8
8/9
9/10
10/11
The equation is
5x - 13 = 3x + 21
when solved, we get
x = 17
