Answer:
increase 20 times
Step-by-step explanation:
when you have a double increase and decrease then you multiply
But if they are different then you divide
5 - increase
4 - increase
<u><em>20- increase</em></u>
Here are the steps. I'll try to make them as easy as possible :)
2/3x+1=5
Step 1: Subtract 1 from both sides.
2/x+1-1=5-1
Step 2: Multiply both sides from 3/2
(3/2)*(2/3x)=(3/2)*(4)
And the answer will be 6
x=6
25 = -16t^2 + 50t + 4
16t^2 - 50t + 21 = 0
16t^2 - 8t - 42t + 21 = 0
8t(2t - 1) - 21(2t - 1) = 0
(8t - 21)(2t - 1) = 0
8t - 21 = 0 or 2t - 1 = 0
t = 21/8 or t = 1/2
t = 2.625 or t = 0.5
