Answers:
Additive Inverse = 1/2
Multiplicative Inverse = -2
========================================
Explanation:
The additive inverse of x is -x. The two add to 0.
So the additive inverse of -1/2 is 1/2 because -1/2+1/2 = 0.
--------------
The multiplicative inverse of x is 1/x
More thoroughly, the multiplicative inverse of a/b is b/a.
We apply the reciprocal operation here.
That means the multiplicative inverse of -1/2 is -2/1 which simplifies to -2.
We can see that (-1/2)*(-2) = 1
Any nonzero value multiplied with its multiplicative inverse will always result in 1.
Answer:
4/9
Step-by-step explanation:
8/2=4
18/2= 9
Gosh, I've done this problem before. Let's start with 13. In this problem, we're basically just skip counting. For example, in the roses row, in the second bouquet, we know we have to add 4 more flowers, so we can document 8. Continue to skip count for both. For 15, we would have about 96 more movie posters remaining, making our ratio 96:x. So, 96:x = 120:100. Therefore, x would equal 80- as 96:80 equals 120:100. If she needs 80 and already had 100, she should sell 20 posters. Hope this helped.
Answer:
The angle in the upper right quadrilateral corner = 68 degrees because vertical angles are equal.
Angle Y = 68 (opposite quadrilateral angles are equal).
All quadrilateral angles add to 360 so:
68 + 68 + x + z = 360 = 292
angle X + Z = 292
Therefore angle x = angle z = 146
