Express b+1/3b-2 with “b” as the subject

Mathematics
1 answer:
lara [203]3 years ago
4 0

Answer:

b = \frac{1+2a}{3a-1}

Step-by-step explanation:

Given

a = \frac{b+1}{3b-2} ( multiply both sides by 3b - 2 )

a(3b - 2) = b + 1 ← distribute left side

3ab - 2a = b + 1 ( subtract b from both sides )

3ab - b - 2a = 1 ( add 2a to both sides )

3ab - b = 1 + 2a ← factor out b from each term on the left side

b(3a - 1) = 1 + 2a ( divide both sides by 3a - 1 )

b = \frac{1+2a}{3a-1}

The perimeter of a triangular field is 84 m, if the ratio of its sides are 13: 14:15, Find the area of the field. *
denis-greek [22]

Answer:

Area = 336\ m^2

Step-by-step explanation:

If the ratio of the sides is 13:14:15, we can say that the length of each side is 13x, 14x and 15x.

Then, if the perimeter is 84 m, we have:

P = 13x + 14x + 15x = 84

42x = 84

x = 2

The length of each side is:

13x = 26\ m

14x = 28\ m

15x = 30\ m

Now, to find the area of the field, we can use the following formula:

Area = \sqrt{p(p-a)(p-b)(p-c)}

Where a, b and c are the sides and p is the semi perimeter:

p = P/2 = 42\ m

So we have that:

Area = \sqrt{42(42-26)(42-28)(42-30)}

Area = 336\ m^2

I need help on the following questions there are 3 files.You may add a file if you prefer.THANKS>
Eddi Din [679]
The first one is 18.5. That was a result of dividing decimals.
Second one is $4.82 because you are trying to find the unit rate. 
Third is 2608.75 dollars earned. You multiply the number of memberships with cost, 152. Now you add that with the monthly earnings, resulting in that answer.
