Answer:
-6
Step-by-step explanation:
-1+(-5)
You are moving down the numberline, then subtracting again because of the negative sign. -(1+5) is how I like to think of it.
So, 1+5=6, and you add the negative sign. -1+(-5)=-6.
You are 22. If you add 22+5 you get 27. And if you divide 27 by 9 you get 3. So it is 22
Step-by-step explanation:
L = length
W = width
L = W + 9
A = 112 = LW = (W+9)W
So,
W2 + 9W = 112
W2 + 9W - 112 = 0
Factoring
(W-7)(W+16) = 0
W = 7, -16
We discard W = -16, since a measurement cannot be negative.
W = 7
And since L = W + 9, then L = 7 + 9 = 16
This is a 16x7 rectangle
2x-2yd=y+xd
2x-y=xd+2yd
2x-y=d(x+2y)
(2x-y)/(x+2y)=d
So the answer is <span><span>d=<span><span>2x−y</span><span>x+2y</span></span></span></span>
x correct answers
23 - x incorrect answers
82 = 4x + -1(23 - x) = 3x - 23
105 = 5 x
x = 105/5 = 21
