Answer:
0.8333333333333333 (repeating)
Step-by-step explanation:
Well first the point of this problem is to get "a" by it self so.
-2a = a - 10/4
remove the fraction by multiplying 4 on both sides.
-8a = 4a - 10
now move 4a over to the other side to isolate the 10.
-12a = -10
now divide to get a by it self
-10/-12 = 0.8333333 (repeating)
**Remember a negative divided by a negative is a positive.
7.8 is rational because it can be written as a fraction with integer numerator and denominator (39/5) and it is also a terminating decimal :))
Answer:
62.5 feet
Step-by-step explanation:
The perimeter of the composite figure is the distance around the figure. It is found by adding each of the side lengths around the figure.
Here P = 4 + 5.5 + 14 + 12.5 + 18 + 8.5 = 62.5
Answer:
x = 42, y = 30
Step-by-step explanation:
From the given figure, we have to find the value of x and y.
The measurement of an angle on a straight angle is 180 degrees.
Using this concept, we have
Now, we know that the sum of consecutive interiors angles is 80 degrees. Hence, we have
Plugging the value of y in equation (1)
Hence, the values of x and y are
x = 42, y = 30
