(PLEASE HELP ASAP!!). One's intelligence quotient, or IQ, varies directly as a person's mental age and inversely as that person'
shusha [124]

Answer:40

Step-by-step explanation:This is a variation question

From the statement. Let the mental age be M and the chronological  age be C, then

IQ ∝M ∝1/C

⇒ IQ ∝ M/C

Introducing the proportionality constant

IQ = KM/ C

Given : M = 15, C = 30 , 1Q = 20

Substitute the given values into the equation

i.e 120 = K x 15/ 30

    120 = k/2

therefore k = 240

substitute k = 240 into the equation, we have

IQ = 240M/C

To find C when IQ is 120 and M is 20, we will substitute into the generated formula

i.e 120 = 240 x 20 / c

     120c = 480

            C = 480/120

             C = 40

Therefore , the chronological age of a person with mental age of 20 and IQ of 120 is 40

Vlada [557]

Answer:

Option C, 6.5

Step-by-step explanation:

<u>Step 1:  Substitute y in the equation 3x - 5y = 22</u>

3x - 5y = 22

3x - 5(-5x + 32) = 22

3x + 25x - 160 + 160 = 22 + 160

28x / 28 = 182 / 28

x = 6.5

Answer:  Option C, 6.5
