The values of the equation will be:
9. 12x - 1
10. -50 - x
11. -x + 14
12. x³ - 4y - 4
13. 8 - 6x
14. 288 - 1080x
15. 420 - y
16. 66 + 7y - 9x
<h3>How to compute the equation?</h3>
9. 4(3x+ 2) - 9
12x + 8 - 9
12x - 1
10. √144 – (62 –x)
12 - (62 - x)
-50 - x
11. (28 ÷ 4) – (x + 7)
7 - x + 7
= -x + 14
12. x³ – 4y - (6 + 2)
x³ - 4y - 4
13. 64 ÷ 8) – (x • 6)
= 8 - 6x
14. 72 (4 - 15x)
288 - 1080x
15. 4(√144 + 93)–y
4(12 + 93) - y
= 420 - y
16. 54 + 7y – (8 + 9x)
= 66 + 7y - 9x

Answer:
a) 10
b) 15
c) 190
d)
Step-by-step explanation:
Lets start with the generic item (d). In order to draw a chord we need to pick two endpoints from the total of n points of the circle and draw the line between them. The total amount of lines we can draw is equivalent to the total pair of points we can pick to draw them.
In other words, we can draw as many chords as the amount of subsets of 2 elements we can pick from a set of n. That number is the combinatorial number of n with 2 given by
a) If n = 5, the answer is
there are 10 possibilities
b) for n = 6
15 possibilities
c) for n = 20, we have
possibilities.
I hope that works for you!
Answer:
The value of brand A=$75 billions
The value of brand B=$28 billions.
Step-by-step explanation:
Let the value of brand B be x billions.
We are told that brand A worth $47 more than brand B.
This implies that in terms of x the value of brand A is (x+47) billions.
Also, the total of both brand is $103 billions. Hence, we can write the following mathematics equation and solve for x.
subtracting 47 from both sides.
Dividing through by 2.
Therefore,
the value of brand B is $28 billions, and
the value of brand A=($28+$47)=$75.
The ration for women to men is:
5:8
104:x
8x104=5x
832=5x
832/5=x
166.4 =x
However, you cannot have 0.4 of a person, so the number of men is 166.
Total number of employees are: 166+104=270
Hope I helped :)
