Identify the property of equality that makes the Equation 1 and Equation 2 equivalent

Mathematics
1 answer:
Otrada [13]3 years ago
6 0

Step-by-step explanation:

<u>To make both equivalent</u>.

For equation (I) multiply all through by 4

Now, from

x - 1/2 = x/4 + 3

it becomes

4(x) - 4(1/2) = 4(x/4) + 4(3)

--> 4x - 2 = x + 12.

This is your new equation (I) or you can call it equation (iii).

For equation (ii) multiply all through by 1 to make it equivalent to your new equation (I) or eqn (iii) if you wish.

Now from

4x - 2= x + 12

it becomes

1(4x) - 1(2) = 1(x) + 1(12)

--> 4x - 2 = x + 12

This is your new equation (ii) or you can call it equation (iv)

Therefore;

Equation 1 has to be multiplied by 4 and Equation 2 by 1 to make both equivalent.

New equation 1 is 4x-2=x+12

New equation 2 is 4x-2=x+12.

Answer:

384, 216, 290, 192, 384

1446, 1 roll

Step-by-step explanation:

For rectangular boxes, calculate the sum of each side, then multiply it by two.

Box 1: 2(18 x 5) + 2(18 x 4) + 2(5 x 4) = 364

Box 3: 2(11 x 8) + 2(8 x 3) + 2(3 x 11) = 290

Box 5 is a cube (all sides equal), so you can find 1 side's area and multiply it by 6.

Box 5: 6(8 x 8) = 384

For triangular boxes, calculate the edges, then find the triangular area using area = 0.5(base x height).

Box 2: (15 x 3) + (9 x 3) + (12 x 3) + 2(0.5)(9 x 12) = 216

Box 4: 2(13 x 2) + (10 x 2) + 2(0.5)(10 x 12) = 192

Total: 364 + 290 + 384 + 216 + 192 = 1446

Rolls of wrapping paper:

Area of 1 roll = 30 x 60 = 1800

Since 1446 is less than 1800, you only need 1 roll of wrapping paper.

Name a point that is not coplanar with points A, B, and C.
boyakko [2]
Points are coplanar if they are located on the same plane. A plane is one of the undefined terms in geometry. It is described as a flat surface in a two-dimensional area. If you look at the given figure, find points that are not included in the shaded plane of points A, B and C. That would be point M or point D.
