Answer:
b = 2A+c
Step-by-step explanation:
A = (b-c)/2
Multiplying both sides by 2
=> 2A = b-c
Adding c to both sides
=> 2A+c = b
OR
=> b = 2A+c
Answer:
Step-by-step explanation:
We are told that the perimeter is 48 = 2L + 2W. This reduces to
24 = L + W. Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:
a) If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm
b) If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm
c) If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm

Answer:
Option D is correct.
Step-by-step explanation:
It is given that 6 feet tall casts shadow for 38 feet long.
We need to find the shadow f 986 ft tall Eiffel tower.
Let's set up proportional equation to solve. Let the shadow length as 'x' feet for the tower.
![\frac{6}{38} = \frac{986}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B38%7D%20%3D%20%5Cfrac%7B986%7D%7Bx%7D)
Cross multiply,
6 x= 37468
Divide both sides by 6.
x= 6244.67 feet approximately.
If we round it to nearest feet, we get 6245 feet.
Given linear equation in standard form x-y=-2.
Let us convert it in slope-intercept form first.
x-y =-2.
Subtracting x from both sides
x-x-y = -2-x
-y = -x-2.
Dividing both sides by -1, we get
y= x+2.
We can write it as y=1x+2.
Let us compare it with slope-intercept form y=mx+b.
On comparing, we get slope m= 1 and y-intercept b=2.
Let us check option -3x+3y=6.
Let us check it by converting in slope-intercept form.
Adding 3x on both sides we get
-3x+3x+3y=6+3x
3y = 3x + 6.
Dividing both sides each term by 3.
3y/3 = 3x/3 + 6/3.
y= 1x +2.
On comparing with slope-intercept form y=mx+b.
We got slope m=1 and y-intercept =2.
So, the equation in option B) -3x+3y=6 create a consistent and dependent system with x-y=-2.
