A)
The question tells us that
y + z = 180
And
y=3x+20
z=x
So we put them in the first formula:
y + z = 180
(3x + 20) + x = 180
Add and get x to one side:
4x + 20 = 180
4x + 20 - 20 = 180-20
4x = 160
Divide both sides by 4
x = 40
B)
Put x back in to equation to get size of each angle:
Y =3x +20
Y=3(40)+20
Y=120+20
Y=140
Z=x
Z=40
Verify: y+z=180
140+40=180
180=180

Step-by-step explanation:
Juan= Paul-0.4
Paul=Terry+1.3
We can substitute Terry+1.3 for Paul since they are equal
juan=(Terry-0.4)+1.3
terry=5.8
juan=(5.8-0.4)+1.3
juan=6.7
Y = 3x - 6....to find the x int, sub in 0 for y and solve for x
0 = 3x - 6
-3x = -6
x = -6/-3
x = 2......so the x int here is 2
y = 3x - 6...when the slope is decreased by 2...
y = x - 6...this is the slope decreased by 2
0 = x - 6
-x = -6
x = 6.....so the x int here is 6
so ur answer is : the x int increases
Step-by-step explanation:
Number of students who wore a hat
= 4/7 * Number of students who bought a ticket
= 4/7 * 350 students
= 200 students.
Number of students not wearing a hat
= Number of students who bought a ticket - Number of students who wore a hat
= 350 students - 200 students
= 150 students.
