Answer: $2.90/cup
Step-by-step explanation:
1 pint = 2 cups
2 cups = $5.80
--> $5.80/2 = $2.90/cup
Associativity means
(A+B)+C=A+(B+C)=A+B+C
Substitute A=9, B=8, C=32 to apply to this problem.
The correct quadratic equation;
x2+7x-2=0
Working
Assuming the frame has a uniform thickness;
Then length of mirror and frame is 3+x and width 2+x
The area of mirror and frame area;
A=L*W
8=(3+x)(2+x)
8=(6+5x+x2)
Taking 8 to the Right hand side, we have:
x2+5x-2 =0
Answer:
im not too sure but my best guess would be
D= 900×T
D= the constant of proportionality multiplied by time to get how many miles traveled.
if the hours given were 1 hour 2 hours & 3 hours
if you multiplied them by 900 you would get the distanced traveled
900 x 1 = 900 miles traveled in one hour
900 ×2 = 1800 miles traveled in 2 hours
sounds good ?
