Answer:
7
Step-by-step explanation:
I made this guess based on the amount of points offered.
a straight line is 180° so:
x+2/3x=180
multiply everything with 3 so that you'll looser the denominator:
3x+2x=540
5x=540
x=540:5
x=108
(2/3x= 72)
Answer:
a - 3.5x
b - 3.5 centimeters per minute
c - this means that in six minutes the water level will be at 21 cm
Step-by-step explanation:
Answer: the equation to determine the value of n is 5n = 105
Step-by-step explanation:
The measure of angle a is n degrees. The measure of angle b is four times angle a. This means that the measure of angle b would be
b = 4n
The measure of angle c is 75 degrees. Since the sum of the interior angles of a quadrilateral is 180 degrees, then the equation to determine the value of n would be
a + b + c = 180
Therefore,
n + 4n + 75 = 180
5n = 180 - 75
5n = 105
n = 105/5
n = 21
