Only 4 books can be bought in the given scenario
Step-by-step explanation:
Let x be the number of books
Then
The cost of books will be represented by 6.50x
According to given statement, that the student cannot spend more than 35
and he also wants to buy one poster worth $5
The inequality will be:
This means that the student can only bur four books and one poster because if he will buy more, the total cost will be more than 30
So,
Only 4 books can be bought in the given scenario

A circle measures 360°.
Since ∠DEF is equal to 70°, the rest of the circle will have a measure of 360 - 70 = 290°.
Central Angle and Arc relationship:
It states that the measure of the central angle and the arc that it intercepts are equal in measure.
Since ∠DEC is a central angle, its intercepted arc DF is also equal to 70°.
With this given facts, arc DGF is equal to 290°.
We can only solve for the degrees because radius is not given. Had it been given, the fraction 290°/360° will be multiplied to the circumference of the circle to get the length of the arc DGF.
Answer:
1. According to the angle bisector theorem, DAC = BAC
2. Same kind of goes for BC
3. X must be equal in both equations. x= 3
9(3) -7 = 20
4(3) +8 = 20
