Marc is half as old as Tony and three times as old as Ben. If the sum of their ages is 40, how old is Marc?
Murljashka [212]

Answer:

Marc's age is 12

Step-by-step explanation:

Let

x ----> Marc's age

y ---> Tony's age

z ---> Ben's age

we know that

the sum of their ages is 40

so

x+y+z=40 -----> equation A

Marc is half as old as Tony

so

x=\frac{y}{2}

y=2x ----> equation B

Marc is three times as old as Ben

so

x=3z

z=\frac{x}{3} ----> equation C

substitute equation B and equation C in equation A

x+2x+\frac{x}{3}=40

solve for x

\frac{10x}{3}=40

x=40(3)/10\\x=12\ years

therefore

Marc's age is 12

The area of a circle is 254.34. Find the radius
Evgesh-ka [11]

Answer:

9

Step-by-step explanation:

area of a circle = pi times radius^2

254.34= 3.14 X r^2    get rid of 3.14 by dividing both sides by 3.14

254.34/3.14= r^2

81= r^2

find the square root of 81=9

What is the equation of the line with slope of - 1/3 and passes through the point (6, -3)?
AURORKA [14]

-1 - ⅓x = y is the answer because of this:

Point-Slope Formula FIRST [GIVEN BOTH SLOPE AND A POINT]: y + 3 = -⅓(x - 6) ["+" was inserted because of (-(-3)) = 3]

Distributive Property: y + 3 = ⅓x + 2

Final Result [deduct 3 from both sides of the equation]: -1 - ⅓x = y (OR y = ⅓x - 1)

You get it?
