Solve the equation. Check your solution. (1/2 is a fraction for one half <br> s-1/2=1/2

Alchen [17]

Answer:

$s = 1$

Step-by-step explanation:

Given

$s - \frac{1}{2} = \frac{1}{2}$

Required

Solve for s

$s - \frac{1}{2} = \frac{1}{2}$

Add $\frac{1}{2}$ to both sides

$s - \frac{1}{2} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2}$

Take LCM

$s + \frac{-1+1}{2} = \frac{1+1}{2}$

$s + \frac{0}{2} = \frac{2}{2}$

$s +0 = 1$

$s = 1$

The diagram below shows the dimensions of Tessa’s garden.

Leona [35]

Answer:

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z -----> the scale factor

x ----> the area of the enlarged garden

y ----> the area of the original garden

$z^{2}=\frac{x}{y}$

we have that

If Tessa multiplies each dimension by 2, then the scale factor equals 2.

$z=2$

substitute

$2^{2}=\frac{x}{y}\\\\ 4=\frac{x}{y}\\\\x=4y$

The area of the enlarged garden will be equal 4 times the area of the original garden

If Tessa wanted to have twice as much surface, she must multiply each dimension by a square root of 2.

therefore

Tessa's mistake was to have multiplied each dimension by two instead of multiplying by a square root of two
