Answer:
I think It would be A but I'm not exactly sure
Answer:
A] A function is a special type of relation for which there is a rule that pairs each input with exactly one output.
Step-by-step explanation:
The right answer is Option A.
Step-by-step explanation:
Let,
x be the postcards
y be the large envelops
According to given statement;
14x+5y=12 Eqn 1
10x+15y=24.80 Eqn 2
Multiplying Eqn 1 by 3;

Subtracting Eqn 2 from Eqn 3;

Dividing both sides by 32

Putting x=0.35 in Eqn 1;

Dividing both sides by 5

Therefore, one large envelope costs $1.42
The right answer is Option A.

Step-by-step explanation:
Answer:
Length =40 ft.
width. = 8 ft.
Step-by-step explanation:
If The length is five times the width , then
width = w
length = 5w
Perimeter of Rectangle = 2( l+b)
2(5w+w)= 96
2( 6w) = 96
12 w= 96
w = 96/12
w= 8ft.
length = 5(8)
= 40 ft
