Answer:

24 years.

B is correct option.

Step-by-step explanation:

Let Sunita's current age is x and that of Mark's is y.

Hence, we have

\frac{x}{y}=\frac{3}{4}\\\\x=\frac{3}{4}y.......(1)

Now, in 12 years the ratio will be 5 to 6. Thus, we have

\frac{x+12}{y+12}=\frac{5}{6}

Cross multiplying, we get

6x+72=5y+60

Plunging, the value of x from equation (1)

6(\frac{3}{4}y)+72=5y+60\\\\\frac{9y}{2}+72=5y+60\\\\\frac{y}{2}=12\\\\y=24

Therefore, Mark's current age is 24 years.

gladu [14]

Answer:

y = -5x + 7

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Define

5x + y = -2

Random point (2, -3)

Step 2: Rewrite

y = -5x - 2

m = -5

Step 3: Write parallel line

y = -5x + b

-3 = -5(2) + b

-3 = -10 + b

7 = b

y = -5x + 7
