Answer:

10

Step-by-step explanation:

Substitute n for 10, 11 and 13

45 - 10 = 35

45 - 11 = 34

45 - 12 = 33

The answer is ten because when substituting n for 10, the equation

35 = 45 - 10

is true

Three siblings sarah, Dave, and Kate - committed themselves to volunteer 155 hours for a homeless charity to build new housing.
adell [148]
S+D+K=155

K=S+10

D=S-20

--------------------------------

S+(S-20)+(S+10)=155

S+S-20+S+10=155

3S-10=155

3S=165

S=165/3=55

---------------------------------

If S=55,

K=55+10=65

D=55-20=35

---------------------------------

Therefore, Sarah had worked for 55 hours, Kate had worked for 65 hours and Dave had worked for 35 hours.

Let f(x)=x2 - 4x - 7 and g(x)=x-3 fins f(g(x))
iris [78.8K]
Answer: x^2 - 10x + 14

Explanation:

f(g(x))
= f(x-3) Since g(x) = x-3

And f(x) = x^2 - 4x - 7

=> f(x-3) = (x-3)^2 - 4(x-3) - 7
=> f(x-3) = x^2 - 6x + 9 - 4x + 12 - 7
=> f(x-3) = x^2 - 10x + 14
