Answer:
1/3 ( 5y-2) = x
Step-by-step explanation:
5y = 3x+2
Subtract 2 from each side
5y -2 = 3x+2-2
5y-2 = 3x
Divide each side by 3
1/3 ( 5y-2) = 3x/3
1/3 ( 5y-2) = x
Answer:
49.2
9
Step-by-step explanation:
7.46² - 2.54² = (7.46 - 2.54)(7.46 + 2.54)
= (4.92)(10)
= 49.2
(1 x 4) x 3 = [1² + √(1 x 4)] x 3 = [1 + √4] x 3 = [1 + 2] x 3 = 3 x 3 = 9
