6(2x - 11) + 15 = 21
First step use distributive property on the left side to remove the parenthesis, to do this multiply 6 by each term inside the parenthesis:
12x - 66 + 15 = 21
Second step, simplify the left side by combining the like terms:
12x - 51 = 21
Third step, add 51 to both sides of the equation:
12x = 72
Last step, divide both sides by 12:
x = 72/12
x = 6
Every cm on the map = 8/2 = 4 km
so 16 cm is equivalent to 4*16 = 64 km Answer
Answer:
A. 15.2%
Step-by-step explanation:
Subtract the new price from the old one to find the dollar amount that the water bottle price was reduced.

The price was reduced by 25 cents, but we need to find the percentage. To do that, we divide the price reduction by the original price.

And then move the decimal place over two spots (multiply by 100)
15.2
The magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively
The formula for calculating the resultant vector is expressed as:

Given the following distances:
u = -5√3 feet (west direction)
v = 5 feet
Substitute the given values into the formula above;

The magnitude of the resultant vector is 10feet
Get the direction:

Since tan is negative in the second quadrant, hence;

Hence the magnitude and the direction angle for the resultant vector are 10N and 120degrees respectively.
