An additive inverse is when 2 numbers added together equals 0

so C and D are additive inverses.

Because : 
C. 12 - 12 = 0
D. -9 + 9 = 0

The sum of two numbers is 18 and the difference is 8
Andrews [41]

Answer:

x = 13 and y = 5

Step-by-step explanation:

x + y = 18

x - y = 8

<u>Step 1:  Find y</u>

x = 18 - y

(18 - y) - y = 8

18 - y - y - 18 = 8 - 18

-2y / -2 = -10 / -2

<em>y = 5</em>

<em />

<u>Step 2:  Plug into x + y = 18 to get x</u>

x + 5 - 5 = 18 - 5

<em>x = 13</em>

<em />

Answer:  x = 13 and y = 5

Trying to help my daughter can't figure this out.
Anvisha [2.4K]

Answer:

width equals 16

length = 20

Step-by-step explanation:

Hello there!

we know that the perimeter is 72 m

and the width is 4 m less then the length

perimeter is 2w+2l

w=width and l = length

72 + (2x-4) = 72+8 = 80

80 / 4 (because there are 4 values, w, w, l, l ) = 20

so now...

20 - 4 = w

16 = w

and 20 = l

16+16 = 32

20+20 = 40

32+40 = 72
