Not sure what you’re trying to find but here’s the simplified version:
-4<=2t+5<11
-9<=2t<6
-9/2<=t<3
This is 1:25 (C)
Explanation:
Answer:
see below
Step-by-step explanation:
2.5 = 2 5/10 = 250%
40% = .40 = 40/100 = 4/10 =2/5
220% = 220/100 = 2 20/100 = 2 2/10 = 2 1/5
1/4 = 25/100 = 25%
4% = 4/100 = .04
Answer: 4
Step-by-step explanation:
x = 5i x =-5i
Step-by-step explanation:
x^2+25=0
Rewriting
x^2 - (-25)=0
Writing as the difference of squares
a^2 - b^2= (a-b) (a+b)
where a = x and b = (sqrt(-25)) =±5i
( x-5i) ( x+5i) =0
Using the zero product property
x-5i =0 x+5i =0
x = 5i x =-5i
