Answer:
x=12
Step-by-step explanation:
3(x-1)=2x+9
3x-3=2x+9
3x-2x-3=9
x-3=9
x=9+3
x=12
Answer:
0.7 is the decimal equivalent to 70/100.
Step-by-step explanation:
You can just do the numerator (70) divided by the denominator (100): 70÷100 = 0.7
Answer:
x^2 + y^2 = 4
Step-by-step explanation:
The center-radius form (formally called the standard form) of a circle is
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center and r is the radius.
So if we replace (h,k) with (0,0) since the center is the origin and r with 2 since the radius is 2 we get:
(x-0)^2+(y-0)^2=2^2
Let's simplify:
x^2 + y^2 = 4
X is the circumcenter of triangle ABC means that X is the center of the circle circumscribed to triangle ABD, as shown in the figure.
This means that All XA, XB and XC are radii of the circle with center X. Since AX and CX are 5.3 cm, then so is XB.
Answer: XB=5.3 cm.
