Answer:
x=6
Step-by-step explanation:
if Q is the midpoint, then its halfway. That means PR=PQ+QR
which means PQ=QR
so...32=3x+14
subtract 14 from both sides
18=3x
divide both sides by 3
18/3=6
3x/3=x
so
x=6
Answer :-For the hexagon construction, every arc along the circle is connected, but for the equilateral triangle construction, every other arc along the circle is connected.
Answer:
n = -6
x = -7
n = 27
Step-by-step explanation:
Question 1
-3n - n + 12 = 36
First we get all the variables to one side using subtraction property of equality.
-3n - n + 12 (-12) = 36 (-12)
-4n = 24
divide by the coefficient of n to isolate the variable
-4n/-4 = 24/-4
n = -6
Question 2
-2x - 3x - 15 = 20
-5x - 15 = 20
-5x = 35
x = -7
Question 3
3 + n/9 = 6
Isolate the n variable
n/9 = 6 - 3
multiply by 9
n = 27
Answer:
x= 8
Step-by-step explanation:
The equation of direct variation is
y = kx
When y = 50 when x = 40
50 = k* 40
Divide each side by 40
50/40 = k
5/4 = k
The equation is
y = 5/4x
Let y = 10
10 = 5/4x
Multiply each side by 4/5
4/5 * 10 = 5/4 x * 4/5
8 = x
