Assuming that the figures given are square such that the scale factor between them is equal to 28/8 which can be further simplified into 7/2. The ratio of the perimeter is also equal to this value, 7/2. However, the ratio of the areas is equal to the square of this value giving us an answer of 49/4.
Hence, the equation for the question (7) is 
and equation for (8) is 
. It can be solved by linear equation in one variable.
What is a linear equation in one variable?
A linear equation in one variable is written as 
. Here, 
and 
are constants and 
is a variable.
(7)
Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.
(8)
Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.
Hence, the equation for the question (7) is and equation for (8) is .

Answer:
8-7r
Step-by-step explanation:
Answer:
2500
Step-by-step explanation:
[8*(3+4-1)+2]^2
First calculate the number inside the round parenthesis as this operation as priority:
3+4-1=6
Then multiply this by 8 because now the multiplication has the highest priority:
8*6=48
Now you can add the 2 to the number you got:
48+2=50
Finally square the number obtained to get the answer:
50^2= 2500
