1
Add 2 to both sides:
Divide both sides by -4 (this is negative, so we have to swap the inequality sign):
2
Expand the left hand side:
Add 8 and y to both sides:
Divide both sides by 3
3-4
Nothing different from 1 and 2, apply the same logic (expand sides, gather constant and non-constant terms together, solve for the variable) and you will solve them
<span>There are 8 students in both Eng and Math.
There are 6 students in both Math and Sci.
There are 5 students in both Eng and Sci.
There are 2 in all the clubs.
Using the Venn diagram, you can determine the number of students in one club only.
There is 1 student in Eng only.
There are 4 in Math only.
There are 3 in Sci only.
The total would be 29 students in at least one of the clubs.</span>

Answer:
arc AC = 111°
Step-by-step explanation:
∠APC is a central angle, so arc AC is equal to the measure of ∠APC.
∠APC and ∠BPC are supplementary. So, m∠APC + m∠BPC = 180
m∠APC + 69 = 180
m∠APC = 111
arc AC = 111°
