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
Step-by-step explanation:
w = 2
x = 5
y = 8
z = 3
= x² + 2y ÷ w + 3z
= (5)² + 2(8) ÷ (2) + 3(3)
= 25 + 16 ÷ 2 + 9
= 25 + 8 + 9
= 42
Answer:
Within the parlance of Statistics, this is called Nominal Data.
Other examples of nominal data are:

2(3+3) or 2(3)+6, so the answer is the third option. It’s just using the distributive property.
Think of this situation as a system of equations.
let y be the price of hotdogs
let x be the price of hamburgers
5y + 2x = 8
2y + 5x = 9.50
now use your solution method of choice
substitution, elimination, matrices, etc
