Answer: 5 weeks
Step-by-step explanation:
In the 1 week he was on vacation, Nolan was able to buy 3 postcards.
The rate he is buying postcards is therefore 3 per week.
If he needed to buy 15, he would need to be there for:
= 15 postcards/ 3 postcards a week
= 5 weeks
Step-by-step explanation:
1.
The given equation is :
6x+2y=14
We need to write it in the function form.
Taking 2 common from both sides,
2(3x+y)=2(7)
So,
(3x+y)=7
Subtract 3x from both sides,
y+3x-3x=7-3x
y = 7-3x
So, the correct option is (c).
2. f(x) = 3x-4
We need to find f(2). Put x = 2 in the above function.
f(2) = 3(2)-4
= 6-4
= 2
The correct option is (D).
Answer:
square root of 121 is 11.
the length have to be 11 feet
the area of a square is
Area=a^2
replace Area with 121
121=a^2
leave a alone by removing ^2
√121=√a^2
11=a
