29 and 25. 29 + 25 = 54 and 29 - 25 = 4
Answer:
15.22
Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm

An equation has the following parts:
1) Coefficient
2) Variable
3) Operator
4) Constants
4x + 3 = 11
4 is the coefficient
x is the variable
3 and 11 are the constants
4x - 3x + 8x ⇒ like terms ; they have identical variable parts, x.
Answer:
x = 29
Step-by-step explanation:
Follow the directions: substitute 13 for y in the first equation.
x + 13 = 42
Subtract 13 from both sides of the equation.
x +13 -13 = 42 -13
x = 29
