so 25/49 = 5^2 / 7^2</span>
She didn’t notice that the 3 and the 4 both do not have the variable “n” with them
She just added up all the numbers together then added the variable at the end.
Answer: A y= -4x + 2
Step-by-step explanation:
y= mx + b
when x is 0, y is 2 which you make the y intercept (b) 2
going from x=0 to x=1, the y coordinate moves down 4, so the slope would be -4

Answer:
6b is a simpler expression that is equivalent to 4b+2b.
Step-by-step explanation:
Given : At a library book sale, hardcover books sell for $4 and paperbacks sell for $2.
The expression 4b+2b represents the total cost for b hardcover books and b paperbacks.
We have to write a simpler expression that is equivalent to 4b+2b.
Equivalent expression are expression which are different in seeing but when we solve both we get the values same as the original expression.
Given expression is 4b+2b,
We can take 2b common from terms to get an equivalent expression as,
4b+2b = 2b(2+1) = 2b(3) = 6b.
Thus, 6b is a simpler expression that is equivalent to 4b+2b.
2 2/5 times 3 1/3 equals 8
