Answer:
A. {16}
Step-by-step explanation:
1/4 = x^-1/2
We have the exponent rule a^-1 = 1/a^1
Applying the rule, we get
1/4 = 1/x^1/2
x^1/2 = √x
1/4 = 1/√x
Now let's cross multiplying, we get
√x = 4
Taking square on both sides, we get
x = 16
The answer: A. {16}

Step-by-step explanation:
Answer: 30 gallons
Step-by-step explanation:
Let the number of gallons that are in a full tank be represented by x.
Since there are 6 gallons in a tank that is 20% full, this will be set up in an equation as:
20% × x = 6
20/100 × x = 6
0.2 × x = 6
0.2x = 6
x = 6/0.2
x = 30
There are 30 gallons in a full tank
(-4) - (- 8) + (- 4)
- 4 - (- 8) + (- 4)
- 4 + 8 + (- 4 )
- 4 + 8 - 4
= 0
If 3 is the bold number then the answer is D. <span>#TeamAlvaxic</span>
