Answer:
12
Step-by-step explanation:
6(d+1)−2d=54
Here, we have to find the value of d
multiply (d+1) by 6
6×d + 6×1 - 2 d= 54
6d + 6 - 2d= 54
Now subtract 2 d from 6d
6d- 2d +6= 54
4 d+ 6=54
Now, by using transposition method,
+ 6 will be transferred from L.H.S to -6 to R.H.S
4 d = 54- 6
4d= 48
Now, divide 48 by 4
d= 48÷ 4
d= 12
Hence, the value of d is 12
Hence, the correct answer is 12
A. Answer: y = 32.913(1.126)ˣ
<u>Step-by-step explanation:</u>
You are given two coordinates (2, 53) and (9, 122). Use these to create a system of equations:
53 = a(b)² and 122 = a(b)⁹
122 = a(b)²· (b)⁷
122 = 53 · (b)⁷
1.126 = b
Substitute the b-value into either of the equations to solve for "a":
53 = a(1.126)²
32.913 = a
Input the a- & b-values into the general form of an exponential equation:
y = a(b)ˣ
y = 32.913(1.126)ˣ

B. Answer: 23 minutes
<u>Step-by-step explanation:</u>
Substitute y = 500 into the equation above to solve for x:
500 = 32.913(1.126)ˣ
To get the answer, do 30,00 / 8
after dividing that you will get the answer 3,750
Given the numbers above and those numbers only the mean would be 1.8
