Answer:

14. x=21, GK=167°, HJ=98°, HGJ=262°, GKJ=201°

15. x=9, AD=108°, BC=23°, DC=139°, DBC=221°

Step-by-step explanation:

In each case, the sum of the arcs around the circle is 360°.

14. 61 +(5x -7) +34 +(9x -22) = 360

14x = 294 . . . . . subtract 66, simplify

x = 21 . . . . . . . . divide by 14

(5x -7) = 98

(9x -22) = 167

x = 21
arc GK = 167°
arc HJ = 98°
arc HGJ = 360° -98° = 262°
arc GKJ = 167° +34° = 201°

15. 90 +(2x +5) +(17x -14) +(12x) = 360

31x = 279 . . . . subtract 81, simplify

x = 9 . . . . . . . . divide by 31

(2x+5) = 23

(17x -14) = 139

(12x) = 108

x = 9
arc AD = 108°
arc BC = 23°
arc DC = 139°
arc DBC = 360° -139° = 221°

What property was applied to solve the equation below? Negative StartFraction 3 over 8 EndFraction x = 48 Negative StartFraction

Soloha48 [4]

Multiplication property of equality

Step-by-step explanation:

We are given that the equation

$-\frac{3}{8}x=48$

We have to find the property which was applied to solve the equation.

$-\frac{3}{8}x=48$

Reason: Given

Multiply by -8/3 on both sides

$-\frac{8}{3}\times -\frac{3}{8}x=-\frac{8}{3}\times 48$

By using multiplication property of equality.

$x=\frac{-384}{3}$

After simplification

$x=-128$
