I don't think that there is a number that can add to 13 exactly, because 12 times 2 is 24 and it equals 14. 3 and 8 equals 11, and 24 and 1 equals 24.

Cross multiplying, we get:

Thus the value of y for given proportion is 18.
Easily, you write the inverse of it without a minus
so if you were to find x^(-2) it would be (1/x)^2
The rest is all the same
Answer:
A
Step-by-step explanation:
The angles in a quadrilateral add up to 360 degrees.
100 + 87 + 106= 293
360 - 293 = 67
The decimal representation for 4/5 would be,
0.8
Hope it helped. It's all I could do.
