Kevin is 4 times as old as Daniel and is also 6 years older than Daniel

MAXImum [283]

Answer:

Part a) Daniel's age is 2 years

Part b) Kevin's age is 8 years

Step-by-step explanation:

The question is

Part a) How old is Daniel?

Part b) How old is Kevin?

Let

x ----> Kevin's age

y ----> Daniel's age

we know that

$x=4y$ -----> equation A

$x=y+6$ ----> equation B

Equate equation A and equation B

$4y=y+6$

solve for y

$4y-y=6$

$3y=6$

$y=2$

therefore

Daniel's age is 2 years

Find the value of x

substitute the value of y in any of the two equations

$x=4(2)=8\ years$

$x=2+6=8\ years$

therefore

Kevin's age is 8 years

Answer 1-6 (about square root)

Taya2010 [7]

Answer:

1. For a cube, volume = $edge^{3}$

2. $\sqrt[3]{volume}$ = edge

3. Volume of the cube = 216 so, the edge = $\sqrt[3]{216}$ = 6

4. 1st blank = 6

2nd blank = 6

3rd blank = 216

4th blank = 216

5. 6 is the edge

6. As the room is a square and we have to find the side

Area = 121

Edge = $\sqrt[2]{121}$ = 11

If my answer helped, kindly mark me as the brainliest!!

Thank You!!
