Sort each equation according to whether it has one solution, infinitely many solutions, or no solution.

Sedaia [141]

Answer:

Equations with one solution: $-2(x-3) = 2x-6$

Equations with no solution:

$6(x+5) = 6x+11\\5(x-2) = 5x-7$

Equations with infinite many solutions: $-3(x-4) = -3x+12$

Step-by-step explanation:

We will solve each equation to see if it has one solution, no solution or infinite many solutions.

An equation where the value of variable can be found has one solution.

An equation with no solution has both sides different.

An equation with infinite solution will have both sides equal after solution(number)

So,

Equation 1:

5(x-2) = 5x-7

$5(x-2) = 5x-7\\5x-10 = 5x-7\\5x-5x = -7+10\\0 = 3$

As both sides are not equal, equation has no solution.

Equation 2:

$-3(x-4) = -3x+12\\-3x+12 = -3x+12\\-3x+3x = -12+12\\0=0\\$

As both sides are equal the equation has infinite many solutions.

Equation 3:

$-2(x-3) = 2x-6\\-2x+6 = 2x-6\\-2x-2x = -6-6\\-4x = -12\\\frac{-4x}{-4} = \frac{-12}{-4}\\x = 3$

As x=3, the equation has only one solution.

Equation 4:

$6(x+5) = 6x+11\\6x+30 = 6x+11\\6x-6x+30 = 11\\30 =11$

The equation has no solution.

Hence,

Equations with one solution: $-2(x-3) = 2x-6$

Equations with no solution:

$6(x+5) = 6x+11\\5(x-2) = 5x-7$

Equations with infinite many solutions: $-3(x-4) = -3x+12$

An interior designer is planning a room but needs to first figure out the dimensions. The length of the room is 23 inches on the

Lostsunrise [7]

Answer:

30.67 feet

Step-by-step explanation:

A proportion is often useful for solving scale drawing problems.

actual size : drawing size = (room length) : (23 in) = (2 ft) : (1.5 in)

Multiplying by 23 in gives ...

room length = (2 ft)(23 in)/(1.5 in) = 46/1.5 ft = 30 2/3 ft

room length ≈ 30.67 ft.

A rectangular photograph is surrounded by a border that is 1 inch wide on each side. The total area of the photograph and the bo

My name is Ann [436]

if 1 inch is added, you would add 2 inches to to each side of rectangle.

You would have: W+2, and, L+2,

Now let W+2 = x and, L+2 = y

Total area = x*y=M

If 1 inch is added again, like above you add 2 inches to both sides, you would then have:

(x+2)(y+2)=M+52;

xy+2x+2y+4=M+52;

xy=M

2x+2y=48

x+y=48/2=24

Now solve :

W+2+ L+2=24

W+L=20

The perimeter is 2(W+L)=20*2 = 40 inches.
