–2|u| = –68<br> ill give 5 oints
german

The solution to the given equation –2|u| = –68 is u = 34, -34.

<h3>What is the solution to the equation?</h3>

Given the equation in the question;

–2|u| = –68

To find u, divide both sides by -2

–2|u| = –68

(–2|u|)/2 = (–68)/-2

|u| = 34

Remove the absolute value term, this create ± on the right side of the equation. ( |x| = ±x )

u = ±34

Hence,

u = 34, -34

Therefore the solution to the given equation –2|u| = –68 is u = 34, -34.

A printer takes 7 minutes to print a document with 63 pages. How many pages
Artemon [7]

Create a proportion.

Since it takes 7 minutes to print 63 pages, and half an hour is 30 minutes, you create two ratios(unit per unit) and line up the units(minutes to minutes, pages to pages).

\frac{7 min}{63 pages} = \frac{30 min}{Xpages}

Now you cross multiply, 63 * 30 = 1890 and 7 * x = 7x.

So we have 1890 = 7x.

Then we divide both sides by seven.

\frac{1890}{7} = \frac{7x}{7}

270 = x, therefore you can print 270 pages in half an hour :)

simon says that to find the area of a trapezoid, you can multiply the height by the top base and the height by the bottom base.
denis-greek [22]
He is correct
basically you have
h times base1+h times bsae 2 all divided by 2
that equals
(hb1+hb2)/2
if we undistribute h using distributive property which is ab+ac=a(b+c)
(h)(b1+b2)/2

if you split the trapezoid in half with a horizontal line that passes through the halfway point of the height and take those two shapes and put them side by side and cut the triangles off the ends and add them, you will see why this is true

the reason is becuase you can get to the area formula from that is height times (b1+b2)/2
