Answer:

B. PQ = 23, QR = 17

Step-by-step explanation:

Given,

In segment PR,

Q is the point between points P and R,

That is, PR = PQ + QR,

We have, PR = 40 unit, PQ = 5x - 2 and QR = x + 12,

By substituting the values,

40 = 5x - 2 + x + 12

40 = 6x + 10

30 = 6x

⇒ x = 5

Hence, PQ = 5(5) - 2 = 25 - 2 = 23 unit,

And, QR = 5 + 12 = 17 unit

just olya [345]

Answer:

$8.40

Step-by-step explanation:

The formula for calculating simple interest is

principal * interest rate * time .

Plugging 140 into the principal, or starting value, 3% as the interest rate, and 2 (years) for the time, we get 140*0.03*2 = 8.4, or $8.40 as our answer. Note that 3% turned into 0.03 as turning a percentage into a decimal requires us to divide the decimal by 100
