Answer:
a. 
b. x = 10
Step-by-step explanation:
a. The number of home runs hit by Jack last season = x
It is given that Henry hit 3 more than half as many home runs as Jack hit.
Half of the runs hit by Jack = 
3 more than half the runs = 
So, the number of home runs hit by Henry =
But, it is given that Henry hit a total of 8 runs.
Therefore,
b.
Subtract 3 from both sides.
= 5
x = 5 × 2
= 10
Hence, Jack hit 10 runs in the last season.
Multiply first
100x50=5000
5000-32=4968
Let's go through each answer choice one at a time.
--------------------------------------------------
Choice A
3/4 < 5/7
3*7 < 4*5 ... cross multiply
21 < 20
The last inequality is false, so the original inequality is false
Choice A is false
--------------------------------------------------
Choice B
2/3 > 5/6
2*6 > 3*5 ... cross multiply
12 > 15
The last inequality is false, so the original inequality is false
Choice B is false
--------------------------------------------------
Choice C
5/8 > 6/10
5*10 > 8*6 ... cross multiply
50 > 48
The last inequality is true, so the original inequality is true
Choice C is true
--------------------------------------------------
Choice D
4/5 < 2/9
4*9 < 5*2 ... cross multiply
36 < 10
The last inequality is false, so the original inequality is false
Choice D is false
--------------------------------------------------
In summary, we have
A. False
B. False
C. True
D. False
So the final answer is choice C

Answer:
3 ≤ n ≤ 10 means "three is less than or equal to n, which is less than or equal to 10"
you're concerned with polygons having 3 to 10 sides, inclusive.
Step-by-step explanation:
The symbol ≤ means "less than or equal to." The compound inequality ...
3 ≤ n ≤ 10
means the value of n may range from 3 to 10, inclusive.
__
In the present context, where n is a number of sides, it means you're concerned with polygons that are any of ...
triangle, quadrilateral, pentagon, hexagon, ...
heptagon, octagon, nonagon, decagon
The area of the circle is
... A = (π/4)d² . . . . where d=10 in
The area of the square is
... A = d² . . . . . . . . where d=10 in
The amount of the square that is not in the circle is
... (1 -π/4)d² = 0.2146018d² ≈ 21.5 in² . . . for d=10 in
