Solve for t q=(s+t)(r/2)

1 answer:

8 0

Isolate the factor (s+t): s+t = q / (r/2). This simplifies to s+t=2q/r.
Subtract s from both sides to isolate t:

t=2q/r - s (Answer).

Alternatively, mult. both sides of q=(s+t)(r/2) by 2 to eliminate the fraction r/2:

2q=(s+t)(r) = sr + tr

Subtract sr from both sides: 2q - sr = tr

Divide both sides by r to obtain an equation for t: (2q/sr) - (sr/r) = t,
or (2q/sr) - s = t

A baseball player has made 32 free throws in 45 attempts for current success rate of 71%. How many consecutive free throws must

s344n2d4d5 [400]

Answer: The player need to make 2 consecutive free throws to raise the average to 75%.

Step-by-step explanation:

Let the number of extra consecutive free throws to raise the average to 75% be 'x'.

Number of free throws already taken = 32

Number of attempts = 45

According to question, it becomes,

$\dfrac{32+x}{45}=0.75\\32+x=45\times 0.75\\\\32+x=33.75\\\\x=33.75-32\\\\x=1.75$
