Identify the variable(s), set up your equation(s), and solve. Richard has an elder sister who is twice his age and a younger sis
alexdok [17]

Answer:

7 years

Step-by-step explanation:

Given that:

Let Richard's age = x

Elder sister's age = 2x

Youngwr sister's age = x - 2

Product of sisters ages = 70

2x * (x - 2) = 70

2x² - 4x = 70

2x² - 4x - 70 = 0

x² - 2x - 35 = 0

x² - 7x + 5x - 35 = 0

x(x - 7) +5(x - 7) = 0

(x - 7) or (x + 5) = 0

x = 7 or x = - 5

X can't be negative

Hence, x = 7

Richard is 7 years

Change -40° to radians.<br><br><br> A). 2π/9<br><br> B). -2π/9<br><br> C). 4π/9<br><br> D). -4π/9
Inessa05 [86]
To solve this, we are going to multiply our degrees by a conversion factor. Remember that 1°=\frac{ \pi }{180}, so to convert -40° to radians, we are going to multiply -40° by the conversion factor \frac{ \pi }{180}; that way we can cancel degrees and express our answer in radians:

(-40°)(\frac{ \pi }{180} )= -\frac{2 \pi }{9}

We can conclude that the correct answer is: <span>B). -2π/9</span>
