Answer:
x = -0.2
Step-by-step explanation:
2.3x+0.37 = 0.7x+0.05
Subtract 0.7x on both sides
1.6x + 0.37 = 0.05
Subtract 0.37 on both sides.
1.6x = -0.32
Divide by 1.6 on both sides to isolate the variable x
x = -0.2

Answer:

Step-by-step explanation:
Divide everything by 2
Divide everything by -1 and since y is negative, you flip the sign

7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>
