Answer:
4b = 8
Step-by-step explanation:
Given 12b = 24
This is written as (4 X 3)b = 24
⇒ 4b X 3 = 24
Dividing by 3 throughout, we have
4b =
= 8.
Therefore, the value of 4b is 8.
B, because if you divide 7 by 9, you get 0.7 repeated, which if rounded is 0.78

Answer:
B and C
Step-by-step explanation:
Vertical angles are formed when you make lines make an x shape (or a turned x shape). The vertical angles are, on a normally positioned x the top and bottom angle, as well as the left and right angle. so every x has 2 vertcial angles unless the x is further split up.
So the part with angles 1. 2. 3 and 4 the top angle is 2, the bottom is 3, the left angle is 1 and the right angle is 4. This means the vertical angle pairs are 1 and 4 as well as 2 and 3.
So in total there are 2 x shapes, so 4 pairs of vertical angles. Here are all the vertical angles.
1 and 4
2 and 3
5 and 8
6 and 7
So from your choices you have 2 and 3 as choice B and 5 and 8 as choice C.
Here is the answer for a:
