Answer:

x = 9

Step-by-step explanation:

congruent angles have the same measure as each other

so;

4x + 14 = 6x - 4

(rearrange)

14 + 4 = 6x - 4x

(solve)

18 = 2x

(simplify)

18 divide 2 = 9

so;

9 = x

A tank has 82 3/4 litres of water, 24 4/5 litres were used, and the tank was filled with another 18 3/4 litres. What is the fina
Marysya12 [62]

Answer:

76  14/20

(76  7/10) simplified

Step-by-step explanation:

First we make the denominator of the fraction equal

82  15/20

24  16/20

18   15/20

We then subtract

82 15/20 -  24 16/20

81  35/20 - 24 16/20 =

57  19/20

Then we add

57  19/20 + 18 15/20=

76  14/20

(76  7/10) simplified

If line VX is the bisector of angle V, find the perimeter of triangle VUW .
umka21 [38]
Since VX is the bisector of angle V and < VXU is a right angle then  UX is congruent to XW and triangle VUW is isosceles with VU = VW.

3z - 4 = x + 6
2z = 10
z = 5

so UW = 3(5) - 4 + 5 + 6  = 22
and VW = 5(5) - 1 = 24

VU = VW = 24 

perimeter = 2(24) + 22 =  70
