Solve for a: b − 2a = c

Mathematics
1 answer:
vlada-n [284]2 years ago
5 0

Answer:

a=-\frac{c-b}{2}

Step-by-step explanation:

Solving for the variable a, given that :

b-2a=c

We can first start start by subtracting b from both sides of the equation:

-2a=c-b

Now, we can divide both sides of the equation by the coefficient of a, which would be -2:

a=\frac{c}{-2}-\frac{b}{-2}

Applying the fraction rule \frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}:

a=\frac{c-b}{-2}

Then, apply the fraction rule \frac{a}{-b} =-\frac{a}{b}

a=-\frac{c-b}{2}

Traffic along a stretch of road moves at an average speed that varies inversely with the number of cars on it. When there are 15
RSB [31]

Answer:

37.5 miles per hour

Step-by-step explanation:

The traffic along a stretch road moves at an average speed that carried inversely as the number of cars

Average speed= k/number of cars.

When there are 1,500 cars the average speed is 45

The first step is to calculate the constant k

45= k/1500

k = 1,500 × 45

k= 67,500

Therefore the average speed when there are 1,800 cars can be calculated as follows

Average speed= 67,500/1,800

= 37.5 miles per hour

Hence the average speed is 37.5 moles per hour
