Answer:

Walt = 48  years

Ralph =  45 years

Henry = 41 years

Step-by-step explanation:

We know that ​Walt is 3 years older than Ralph so we can write,

Walt = 3 + Ralph        eq. 1

We also know that Ralph is 4 years older than Henry so we can write,

Ralph = 4 + Henry      eq. 2

It is given that Walt's age is 48 years so substitute it into eq. 1

Walt = 3 + Ralph

48 = 3 + Ralph

Ralph = 48 - 3

Ralph = 45 years

Now substitute the age of Ralph into eq. 2

Ralph = 4 + Henry

45 = 4 + Henry

Henry = 45 - 4

Henry = 41 years

Therefore,

Walt = 48  years

Ralph =  45 years

Henry = 41 years

Verification:

Walt = 3 + Ralph        eq. 1

48 = 3 + 45  

48 = 48 satisfied

Ralph = 4 + Henry      eq. 2

45 = 4 + 41

45 = 45 satisfied

Answer:

Ralph is 45 and Henry is 41

Step-by-step explanation:

if Walt is 48 to find Ralph you subtract 3 because Walt is 3 tears older than Ralph.

to find Henry you subtract 4 from Ralph and get 41

ok so for the 2 ft pillows the perimeter would be 8 ft and for the 1 ft pillows the perimeter would be 3 ft. So you would need 8(2)+3(3)=16+9=25 so she needs 25 feet of trimming.

Answer:

Total area to be painted in gold = 24000 cm²

Step-by-step explanation:

Total height of the stairs = 120 cm

Total standing stairs = 4

Therefore, height or width of one standing stair as shown in the picture,

= \frac{120}{4}

= 30 cm

Length of every stair has = 100 cm

Every horizontal and vertical stair has the same area.

Area of one stair = Length × Width

                            = 100 × 30

                            = 3000 cm square

There are 4 horizontal and 4 vertical similar stairs to be painted in gold.

Total area to be painted in gold = 8 × Area of one stair

                                                     = 8 × (3000)

                                                     = 24000 cm²

Total area to be painted in gold = 24000 cm²
