Step by step:

$5x - 17 = -x + 7$, then add x to both sides:

$6x-17=7$, add 17 to both sides:

$6x=24$, divide both sides by 6:

$x=\boxed{4}$

What is the value of $b+c$ if $x^2+bx+c>0$ only when$x\in (-\infty, -2)\cup(2,\infty)$?

So this is a parabola that opens up and has x intercepts at (-2,0) and (2,0). The slope is 1. So the equation of the graph is $x^2-4$. Making b=0 and c=-4, so $b+c=\boxed{-4}$

I wish counting was that easy lol.

Love that unusual answer, and how you noticed that being outside the box.

what?!? the question never tooks about the angles and the altitude of a right triangle where the altitude goes through the right angle does not always suggest that it forms a 30-60-90 triangle. Think about it. @Guest is right here.

Yeah why don't you get better rackets. Birdies are important too.

You asked this question earlier in a different language???

I assume that you mean 45 minutes earlier, if so then x is the miles you drove:

60x/40-45=60x/50,

3x/2-45=6x/5

3/10x-45=0

3/10x=45

3x=450

x=150

You drove 150 miles.

Sizning savolingiz meni juda chalkashtirib yubordi, birinchi jumla raqamning juft bo'lishidan tashqari unchalik ahamiyatli emas, lekin bu keyinroq tajribadan keyin berilgan. Lekin qanday qilib x4y soni (bu erda x - yuzlar soni va y - birliklar soni) x+y ga teng bo'lishi mumkin, bu shunchaki mumkin emas. 

Shuningdek, u 13 yoshgacha va undan katta bolalar haqida gapiradi. U 13 yoshga to'lgan bolalar haqida hech narsa aytmaydi, bu ko'plab stsenariylarni amalga oshirishga imkon beradi (ammo lagerdagi 100 13 yoshli o'smirlar boshqa yoshdagilarga nisbatan imkonsiz ko'rinadi).

yes i did use a translator
