The given equation, a = (2b + 10) / 6, solved for b is b = 3a - 5
<h3>Solving an equation for a variable</h3>
From the question, we are to solve the given equation for b.
From the given information,
The given question is
a = (2b + 10) / 6
Now, to solve the given equation for b, we will make b the subject of the relation.
Solving the equation for b
a = (2b + 10) / 6
Multiply both sides of the equation by 6
6 × a = 6 × (2b + 10) / 6
6a = 2b + 10
Subtract 10 from both sides of the equation
6a - 10 = 2b + 10 - 10
6a - 10 = 2b
Divide through by 2
6a/2 - 10/2 = 2b/2
3a - 5 = b
Therefore,
b = 3a - 5
Hence, the equation solved for b is b = 3a - 5

Answer:
7th
Step-by-step explanation:
63 - 58 = 5
68-63 = 5
She is adding 5 points each time
a1 = 58
d = 5
a2 = 63
a3 = 68
a4 = 58+5 = 73
a5 = 73+5 = 78
a6 = 78+5 = 83
a7 = 83+5 = 88
This is the first assessment greater then 85, so the 7th assessment
Answer:
x= 35
Step-by-step explanation:
Cos x = Sin( 20+x)
Sin ( 90 – x) = Sin(20+x)
90 – x = 20+x
2x = 70
x = 35
