8%,3/5,7/10 and .8
8% = .08
3/5 = .6
7/10=.7
.8=.8
Answer:
Vertical angles = 81 degrees
Angle (4y-1) = 99 degrees
Linear pair = 81 + 99 = 180 degrees
Step-by-step explanation:
2x + 5 = 3x - 33 (vertical angles)
33+5 = 3x - 2x
38 = x
3(38) - 33 = 81 degrees
4y - 1 + 81 = 180 (linear pair angles)
4y = 180 - 80
y = 100/4
y = 25
4(25) -1 = 99 degrees
Answer:
x=62°
z=105°
y=24°
the reason are included in picture..
Find the proportional relationship in a unit rate.
x:y
Put in x and y.
60:25
Divide both sides by 5.
12:5
So, every 5 units of y, there are 12 units of x.
Put the new y into proportion.
x:30
There are 5 extra units of y.
All you need to do is add 12 to the previous x.
60+12= 72
x=72
I hope this helps!
