6x-4>8-2x
Add 2x on each side
8x-4>8
8x>12
x>12/8
x>3/2
The answer is B
Answer:
Step-by-step explanation:
Let Freda's sum = x
Donnie has 3/4 x
He spends 63 dollars. His sum is now
3/4x - 63
Now the equation looks like this
6(3/4x - 63) = x Remove the brackets
6*3/4 x - 378 =x
6 * 3/4 = 4 1/2
4 1/2 x - 378 = x Add 378 to both sides
4 1/2 x = x + 378 Subtract x from both sides
3.5 x = 378 Divide by 3.5
x = 378 /3.5
x = 108
Since x = 108, that's how much Freda had. (She spent nothing).
Answer:
a = 157.7536pi
Step-by-step explanation:
area = pi*circumference²
a = pi*12.56² = 157.7536*pi
however, if pi just equals 3.14:
probably around 495.346304
It is zero and three tenths
Answer:
96
Step-by-step explanation:
From the given information:
At 95% Confidence interval level,Level of significance
0.05, the value of Z from the standard normal tables = 1.96
Margin of Error = 0.10
Let assume that the estimated proportion = 0.5
therefore; the sample size n can be determined by using the formula: 


n = 96.04
n
