Find the value of each variable.
a. x=38, y=76
b. x=52, y=76
c. x=38, y=104
d. x=52, y=104

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

I’m really confused and need to learn this

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3
