3(5b-1)=5
Get rid of the brackets
15b-3=5
add 3 to both sides of the equation
15b=8
divide both sides of the equation by 15
b=0.53
4(3y-1)=20
12y-4=20
12y=24
y=0.5
question one
1, 2, 3, 4, 5, 6
question two
3/6 or 1/2
question three
3/6 or 1/2
question four
2/6 or 1/3
question five
4/6 or 2/3
you use the list from question one, and count how many fit the criteria and put that number over the total ( which is 6 in this case )
Answer:
105°, 75°, and 105°.
Step-by-step explanation:
If two straight paths intersect at a point , four angles will be formed.
These are pairs of vertical angles.
The adjacent angles add up to 180°
If one of the angles is 75°, the supplement will be

Therefore the three other angles will be , 105°, 75°, and 105°.
