Evaluate the expression 2y + 3.5. Evaluate the expression for y=1.8, y=4, y=6.9. (there should be three answers)
1 answer:
Answer:
1. 7.1
2. 11.5
3. 24.2
Step-by-step explanation:
you use P.E.M.D.A.S. for all the equations.
so you do thr multiplication and then the addition
1. 2(1.8)+3.5= 3.6+3.5= 7.1
2. 2(4)+3.5= 8+3.5=11.5
3.2(6.9)+3.5= 13.8+3.5= 24.2
hope this helps

Hope you pass!
I want to say it is A because if you simplify it then it should say 36x/6x. I hope this helps! If wrong correct me..
(2x² - 8x - 10) ÷ 2 = 0
x² - 4x - 5 = 0
x² + x - 5x - 5 = 0
x(x+1) - 5(x+1) = 0
(x+1)(x-5) = 0
x+1 = 0 or x-5 = 0
x = -1 or x= 5
S = {-1;5}
