Chen’s house is 53 years old. This is 5 more than twice the age of Sunny’s house, h.

tankabanditka [31]

Answer:

The Equation which shows the equality is 53 = 2 h + 5 ,

The age of Sunny's house is 24 years old

Step-by-step explanation:

Given as ;

The age of the house of Chen's is 53 years old

Let the age of of the house of sunny = h years old

So, according to question

Chen's house age is 5 years more than twice the age of sunny's house

I.e Chen's house age = 2 × sunny's house age + 5

Or, 53 = 2 × h + 5

or, 2 × h = 53 - 5

so . 2 × h = 48

∴ h = $\frac{48}{2}$ = 24 years

Hence The Equation which shows the equality is 53 = 2 h + 5 , And The age of Sunny's house is 24 years old . Answer

What is the value of p such that the line passing through (6,2) and (9,p) has a slope of -1?

Aleks [24]

Answer:

p= -1

Step-by-step explanation:

gradient=y²-y¹

x²-x¹

-1 =p-2

9-6

-1=p-2

3

multiply both sides by 3 to remove the denominators

-1×3=p-2

-3=p-2

put the like terms together

-3+2=p

-1=p

Jamar has a large rectangular box that is 6ft x 8ft x 7ft. Will this box fit a pipe that is 12 ft. Long? Determine the length of

Sav [38]

Answer:

9.21ft

Step-by-step explanation:

Given data

L= 6ft

W= 8ft

H= 7ft

Let us find the diagonal of the side, this represents the longest size of pipe the box can take

z^2= L^2+ H^2

z^2= 6^2+ 7^2

z^2= 36+49

z^2= 85

z= √85

z= 9.21ft

Hence the 12ft cannot fit into the box

the length of pip that can fit is 9.21ft
