220% is 2.20 in decimal form in fraction 2 1/5
Answer:
x=-2 and x=0
Step-by-step explanation:
5(x-2)^2 = 20; divide by 5 both sides
(x-2)^2 = 4; take the square root of both sides
(x-2) = ±2, now set it equal to positive 2 and negative 2
x-2 = 2
x=4
AND
x-2 = -2
x=0

Answer:
27
Step-by-step explanation:
If 6x-4 is 11 less than 25, what is the value of 9x can be rewritten as:
6x-4=25-11, what is the value of 9x?
Let's solve for x first by using the given information: 6x-4=25-11
1. 6x-4=25-11
2. 6x-4=14
3. (isolate x by adding 4 on both sides) 6x=18
4. x=3
The question asks for the value of 9x. Since we know x=3...
9x=9 times 3=27
9x=27
