Answer:
a. -200
Step-by-step explanation:
Square root both sides:
x = +/- 200
x = -200, 200
x = -200
Answer:
48
Step-by-step explanation:
Let n represent the number. "The quotient of a number and 4" is represented by (n/4). To represent decreasing that value by 10, we write ...
(n/4) -10
We are told this "is two":
(n/4) -10 = 2
n/4 = 12 . . . . . . . add 10
n = 48 . . . . . . . . multiply by 4
The number is 48.
Answer:
D. 4
Step-by-step explanation:
Percent of drivers who wear seat belts = 68
Percent of drivers who do not wear seat belts = 100 - 68 = 32
Now, we know that for every 100 pull overs, 32 drivers will not be wearing belt.
32 drivers without seat-belt = 100 pullovers
1 driver without seat-belt = 100/32 pullovers
1 driver without seat-belt = 3.125 pullovers (4 pullovers)
So, a police officer should expect 4 pullovers until she finds a driver not wearing a seat-belt.
Hi there! The answer is 12.6
First we need to change the percentage into a decimal. To convert this percentage, we have to divide it by 100.

Hence, to find 3 percent of 420, we must multiply 420 by 0.03. We get the following:

Answer:
x - 4y = 8
Step-by-step explanation:
Since the Point-Slope Formula is already given to you, convert it to Slope-Intercept Form, and you do that by doing this:
y - 1 = ¼(x - 12) >> y - 1 = ¼x - 3
y - 1 = ¼x - 3
+ 1 + 1
--------------
y = ¼x - 2 >> Slope-Intercept Form
After doing this, you are ready to convert to Standard Form, and you do that by doing this:
y = ¼x - 2
-¼x -¼x
-----------
-¼x + y = -2
Now unfortunately, we do not want fractions as our coefficients, so the way to eliminate the fraction is to multiply the equation by the Multiplicative Inverse of -¼, which is -4:
-4[-¼x + y = -2] >> x - 4y = 8 → New equation without fractions
