Answer:
x = 18 , y = 45
Step-by-step explanation:
The angle vertically opposite 4x - 7 is congruent to it and forms a same- side interior angle with 6x + 7.
Same- side interior angles sum to 180° , then
6x + 7 + 4x - 7 = 180 , that is
10x = 180 ( divide both sides by 10 )
x = 18
Then
6x + 7 = 6(18) + 7 = 108 + 7 = 115
6x + 7 and 3y - 20 are vertically opposite angles and are congruent , so
3y - 20 = 115 ( add 20 to both sides )
3y = 135 ( divide both sides by 3 )
y = 45
To find the unit rate, we need to divide 6 by 51.
51/6 = 8.50

Answer:
7.)
m<1 = 141
m<2= 39
m<3 = 141
8.)
m<1 = 17
m<2 = 73
m<3 = 107
9.)
m<1 = 101
m<2 = 33
m<3 = 71
Step-by-step explanation:
use the postulates and theorems your teacher gave you.
Also you need some logic
You find the GCF of 250 and 363 by factoring. 250 = 5^4 * 2. 363 = 3 * 11^2, and they have no common factors, so 250/363 is already in its simplest form!
