X - an amount

$x+3\%x=x+0.03x=1.03x$

To increase an amount by 3% you can multiply the amount by 1.03.

−10x + 6(x − 5) = 12x − 62

tankabanditka [31]

Answer:

$x=2$

Step-by-step explanation:

So we have:

$-10x+6(x-5)=12x-62$

Distribute:

$-10x+6x-30=12x-62$

Combine like terms:

$-4x-30=12x-62$

Subtract 12x from both sides:

$-16x-30=-62$

Add 30 to both sides:

$-16x=-32$

Divide both sides by -16:

$x=2$

And that's our answer :)

Thrice the square of m diminished by 5 gives 22

Romashka [77]

Answer:

Step-by-step explanation:

3m² - 5 = 22

3m² = 22 + 5

3m² = 27

m² = 27/3

m² = 9

m = √9 = √3*3

m = 3

What is the approximate length?

Usimov [2.4K]

9514 1404 393

Answer:

(a) 75.5

Step-by-step explanation:

There are two ways you can work this.

Pythagorean theorem

Triangle CMP is a right triangle. CM = AC = 55. CP = CB -PB = 55 -15 = 40. Then length PM can be found from ...

PM² +CP² = CM²

PM = √(CM² -CP²) = √(55² -40²) = √1425 ≈ 37.749

The length MN is twice the length of PM, so is ...

MN = 2×PM = 2×37.349 = 75.498

The length of MN is about 75.5.

Using chord relationships

The products of the different lengths for the same chord are the same for the crossed chords.

AP×PB = MP×PN

We know MP = PN, so ...

MP = √(AP×PB) = √((55+40)(15)) = √1425

As before, MN = 2×MP = 2√1425

MN ≈ 75.5
