Cut the shape into two shapes. The bottom will be a square and the top will be a long rectangle.

The area of the rectangle is 18 square feet
(Multiply 9 x 2)

The area of the square is 16 square feet
(Multiply 4 x4)

18 + 16 = 34

Which equation, when solved results in a different value of x than the other three?

Talja [164]

Answer:

$-\frac{7}{8}(-\frac{8}{7})x-\frac{3}{4}=20(-\frac{8}{7})$

Step-by-step explanation:

<u><em>The complete question in the attached figure</em></u>

<em>Verify each case</em>

Part 1) we have

$-\frac{7}{8}x-\frac{3}{4}=20$

solve for x

$\frac{7}{8}x=-\frac{3}{4}-20$

$\frac{7}{8}x=-\frac{83}{4}$

$x=-\frac{83}{4}(\frac{8}{7})$

$x=-\frac{166}{7}$

Part 2) we have

$\frac{3}{4}+\frac{7}{8}x=-20$

Multiply both sides by -1 and rearrange the terms on the left side to get

$-\frac{7}{8}x-\frac{3}{4}=20$

This expression is the same that the expression in Part 1)

That means, that the equations Part 1) and Part 2) are equivalent

therefore

$x=-\frac{166}{7}$

Part 3) we have

$-7(\frac{1}{8})x-\frac{3}{4}=20$

Remember that

$-7(\frac{1}{8})x=-\frac{7}{8}x$

This expression is the same that the expression in Part 1)

That means, that the equations Part 1) and Part 3) are equivalent

therefore

$x=-\frac{166}{7}$

Part 4) we have

$-\frac{7}{8}(-\frac{8}{7})x-\frac{3}{4}=20(-\frac{8}{7})$

This equation is not equivalent to the other three, because some terms are multiplied by -8/7 and others are not. When different things are done on either side of the equal sign, it changes the equation, resulting in a different solution

Find the simple interest on $350 invested at 6% yearly for ten years

topjm [15]

Answer:

It would have $560 after ten years.

Step-by-step explanation:

1) find 6% or .06 of 350

350 x .06 = 21

2) multiply that by the ten years to get how much it will be after that time

21 x 10 = 210

3) add your interest over the 10 years to your original amount

210 + 350 = 560
