Step-by-step explanation:
13x + 15 = 19x - 9 ( being opposite sides of parallelogram)
19x - 13x = 15 + 9
6x = 24
x = 24 / 6
x = 4
4y + 7° + 10y - 37° = 180° {being co-interior angles }
14y = 180° - 7° + 37°
14y = 210°
y = 210°/ 14
y = 15°
Hope it will help :)
Let x be the number of children
Let y be the number of adults
x + y = 4
4x + 7y = 19
Answer: Negative 1 The slope of parallel lines is the same.
The attachment shows two such lines, given coordinates labeled.
Step-by-step explanation:
Find the slope of the line passing through the given points.
rise/run
Rise is the difference in y-values 7-(-5) = 12
Run is the difference between x-values -5 - 7 = - 12
The Slope is 12/-12 simplify:
slope = -1
Answer:
0.1 is rational as it can be written as 
Step-by-step explanation:
Rational decimals can be expressed as a fraction using integers, and 0.1 =
, so it is rational.
The square of 4 and 2 adds up to 20!
4 square is 16.
2 square is 4
So 16+4=20
