Answer:
5 3/5 is already a mixed number
3 4/9 is also already a mixed number
43/9 = 36/9 + 7/9 = 4 7/9
32/5 = 30/5 + 2/5 = 6 2/5
Answer:
2 years old
Step-by-step explanation:
4×2=8
8-2=6
-13k + 7k - 4 = 23 + 16k - 2
-13k + 7k - 16k = 23 - 2 + 4
-22k = 25
k = 25/-22
Answer: B
Step-by-step explanation:
You are given the function
p(x) = √5x+7
Let p(x) = y then,
Y = √5x+7
To find the inverse of a function, you need to interchange x and y and make y the subject of formula. That is,
X = √5y+7
Square both sides
X^2 = 5y + 7
Make y the subject of formula
5y = x^2 - 7
Y = ( x^2 - 7 ) / 5
the correct answer is B
