Answer:
Angles of a quadrilateral add up to 360
so x+36+72+144=360
x+252=360
x=360-252
x=108
So B is the correct answer
Step-by-step explanation:
Answer:
-4
Step-by-step explanation:
First, you can distribute the -2 to 1 - 7n
the new equation is 5n + 34 = -2 + 14n
then, you can add 2 to both sides to cancel the -2 on the right
now you have 5n + 36 = 14n
after this, you add -5n to both sides, again, to cancel the 5n on the left
you are left with 34 = 9n
lastly, divide both sides by 9 to find the value of n, which is 4.
Answer/Step-by-step explanation:
Since there is a proportional relationship between amount of seed a landscaper uses and the area of lawn covered, therefore: constant of proportionality = area covered / seed.
The constant of proportionality would be same for all pairs of values given in the table.
