The pans shown are balanced. Use the SubtractionProperty of Equality to find which shapes are equalto one purple pyramid.
Bad White [126]

According to the Subtraction property of equality, the equality of an expression holds true if the same finite number is subtracted from both sides of the equality,

a=b\Rightarrow a-c=b-c

Now, observe the given figure carefully.

We will use the above-mentioned property to get rid of the common shapes that exist on both sides. Here, the balance represents equality between both sides.

Consider that the pans are initially balanced. And both sides contain a red cube. So we can subtract or eliminate the red cube and the equality will still hold true.

Similarly, we can eliminate the blue sphere.

At this point, we have the purple pyramid and a yellow diamond on the left side, and on the right side, we have 4 pieces of yellow diamond.

Observe that one piece of yellow diamond is common to both sides, so it can also be eliminated from both sides.

After this, the left side will contain only the purple pyramid while the right side contains 3 yellow diamonds. Since we are always using the subtraction property to eliminate the shapes, the balance must be maintained throughout the process.

At last, there must exist a balance between the left side containing the purple pyramid only, and the right side containing 3 yellow diamonds.

Therefore, it can be concluded that one purple pyramid is equal to 3 yellow diamonds.

I need major help. I have a lot of missing work and really need help with algebra 1. (solving linear equations)
igor_vitrenko [27]
A= 5 + 2 = 7
You get this by doing the inverse operation so minus 2 by 2 and 7 then you get your answer so it should look like this
X+2= 7
-2. -2
———
X= 5

B: 15-4=11
+4. +4
————-
X= 15

C: 4(3) = 12

D: 50/5 = 10

Btw this should be easy, try doing it on to your own now.

A rectangular piece of land to be developed as a memorial park has an area of 75 m^2. The length of the lot is three times the w
Lelechka [254]

Let length = l

width = w

length = 3 times width = 3w

Area of the land = 75 sq. m

Area = length × width = 3w×w = 75

3w²=75

w²=25

w=5 m

length = 3×15 = 15m

Now lets make the figure with the path of width x meters

(Refer the attached figure for easy understanding)

The inner length is the length of the rectangle reduced by x meters on either side due to the path

that is 15-x-x = 15-2x

the inner width is the width reduced by x meters in either side

= 5-x-x = 5-2x

Now lets calculate the inner area = inner length × inner width

(15-2x)×(5-2x)

= 75-30x-10x+4x^{2}

= 75-40x+4x^{2} sq. m

Now the function to calculate the cost

f(x) is given by $3.00 × area of the inner land

f(x) = 3 × {75-40x+4x²)

= 225-120x+12x²

or

= 12x²-120x+225
