Answer:
Answers for 19, 20, 22, 24, and 25.
Step-by-step explanation:
19. 23x - 16 + 8x - 21 = 180
x = 7
23 (7) - 16 = 7y - 23
y = 24
20. 10x -17 = 8x + 1
x = 9
6y + 29 + 73 = 180
y = 13
22. 8x - 35 + 6x - 5 + 3x - 1 = 180
x = 13
24. m<R is 74
m<Q is 32
25. m<E is 37
m<G is 37
I didn't know the answers for all, but I hope this helps in some way!
The required inequality statement tonmode’ the scenario given is : 16 + 6s ≥ 40
- The number fencing leftover = 8 foot × 2 = 16 feet
- Required number of fencing ≥ 40
- The additional number of 6 foot fencing required = s
Representing this as an inequality :
- Left over + additional fencing ≥ 40

Answer:
D - Area = 9/16pi cm²
Step-by-step explanation:
in order to evaluate this question , we will first of all find the radius using the formula for finding the circumference of a circle , we will then find the area of a circle.
<u>solution</u>
given that circumference of a circle = 3/2picm
recall that the formula for finding the circumference of a circle = 2πr
3/2picm = 2πr
multiply through by 2
3picm = 4pir
divide both side by 4pi
3pi cm/4pi = r
r = 3/4 picm
Recall that the Area of a circle = πr²
Area = pi ( 3/4)² cm
Area = 9/16pi cm²
