The multiplicative inverse of a number is the number when you multiply it, it gives you the product of 1.
So for - 27, what number will give us 1 when we multiply it by -27
-27 * -1/27 = 1
So the multiplicative inverse of -27 = -1/27
7/9 * 9/7 = 1
-9/16 * -16/9 = 1
So in essence, just take the number and flip it
-27 = -1 / 27
7/9 = 9/7
-9/16 = -16/9
Answer: Answers provided below in sequential order.
Step-by-step explanation: UV = 12(3)-1
(They said that x = 3)
UV = 35 (12*3-1)
70 = TV
TU = UV
8x + 11 = 12x - 1
-4x = 10
x = -10/4 or -5/2 (simplified)
TU = 8 (3) + 11
TU = 35 (24+11)
Multiply the first equation by -1
-3x-y=-4
2x+y=5
Add them up
-x=1
So x=-1
And y=7
So the first option is correct
Answer:
d
Step-by-step explanation:
Soooo,
d = 2r
(29) = 2r
29/2 = 2r/2
14.5 = r
Answer:
The perimeter is 20 cm.
The area is 25 cm^2.
Step-by-step explanation:
The perimeter is the distance around the figure.
This is a square, so each side is the same length.
There are four sides, so
5 + 5 + 5 + 5 = 20 cm
The area of the figure is
s^2
where s is a side
so 5 * 5 = 25 cm^2
