Answer:
38 %
Step-by-step explanation:
1. Percent of lawns mowed
2. Percent of lawns unmowed
% Unmowed = 100 % - 62 % = 38 %
Henry still needs to mow 38 % of the lawns.
The range of a function are the possible outputs, here { 2, 6, 8 }.
Answer: D
Answer:
x = 2, y = 3
Step-by-step explanation:
i) It is given that 5x - 3y =1
ii) It is also given that x = 2y - 4
iii) we can substitute the value of x from ii) in the equation in i) and we will get 5(2y - 4) - 3y = 1 ⇒ 10y - 20 -3y = 1 ⇒ 7y = 21 ∴ y = 3
iv) substituting the value of y obtained in ii) we get x = (2 × 3) - 4 = 6 - 4 = 2.
v) Therefore x = 2.
