Answer:
the answer for this question is (y-5)/4=x
So we know that all triangles equal 180 degrees, basically the equation will look like this
(7x-11) + (2x-3) + (5x-2) = 180
So first we need to collect like terms
7x + 2x + 5x -11 - 3 - 2 = 180
= 14x -16 = 180
Then we need to move the constant to the right
14x = 180 + 16
Then add
14x = 196
Then divide both sides
The answer is 14 :)
Is it adding or subtracting
Answer:
h = 3v/b
Step-by-step explanation:
Here, we want to select the equation that solves for h
What this simply means is that we should make h the subject of the formula
Thus, we have 3 * v = bh
3v = bh
h = 3v/b

Answer:
13 cm wide; 15 cm long
Step-by-step explanation:
Let w represent the original width. Then the original length is (w+2) and the original area is w(w+2). After the decrease, the width is (w-1) and the length is (w+1). The decreased area is (w-1)(w+1). The difference between these areas is 27, so we have ...
w(w+2) -(w-1)(w+1) = 27
w^2 +2w -(w^2 -1) = 27
2w +1 = 27
w = (27-1)/2 = 13
The original piece of cardboard was 13 cm wide and 15 cm long.
