Two boys' ages total 24. Four less than six times the younger boy's age equals five more than three times the older boy's age. W

babunello [35]

Hey there!

Let x be boy 1's age, and y be boy 2's age (younger).

Firstly, we know that x+y=24

6y-4=3x+5 <== we have this right here. (using the rules given by the question)

We can use all the equations to help find the answer.

x+y=24

x+y (-y)= 24(-y)

x=24-y

Plug that into x in the equation we made above.

6y-4= 3(24-y)+5

6y-4= 72-3y+5

Add 4 to each side.

6y= 81 -3y

9y=81

y=9

We know the younger boys age is 9.

We can plug that in to find the older one's age.

x+9= 24

x= 15

The boy's ages are 9 and 15.

I hope this helps!

-3 w - 5 (6 z - 2 W) - 5 z
-5 (6 z - 2 W) = 10 W - 30 z:
-3 w + 10 W - 30 z - 5 z
-30 z - 5 z = -35 z:
Answer: -3 w + 10 W + -35 z

Step-by-step explanation:

Given:

Let p be the Length of Rectangle

Let r be the Width of Rectangle

To Find:

Perimeter of Rectangle = ?

Solution:

Perimeter of Rectangle:

Sum of Twice Length and Twice Width,

i.e

$\textrm{Perimeter of Rectangle}=2\times Length + 2\times Width$

So we will have

$\textrm{Perimeter of Rectangle} =2p+2r......................as\ required$

(2p + 2r) expression represents the perimeter of the rectangle.

The correct option is D )

D ) 2p + 2r
