Hey I'm also studying for my college entrance exams! Good luck to you shawty

Looks like the 3 of us found a way here

I am also after 3 years of graduating high school I've decided to go back for physics.

kudos to you cuz you are filling those gaps over algebra and learning basics to help you in the future. It is nothing to be ashamed of learning lower grade classes cuz learning is a continuous process

I'm in my 3rd year in College and i came here too 😅

May I ask where are you from?

Hehehehehehehhehehhehe

thanks for this i needed it

My brain is physically twisted. I can't seem to think abstractly whatsoever. I spent 30 minutes going over the easy warmup problem and then took a break, came back and it's still not clicking. It's physically hurting.

omg thx so much - i was getting stuck

I have a question: How did you get a singular B at "2B-5+B=70'?

@@kingthief9118 My understanding is the first part is Red has twice the amount of Black minus 5. So because of this you still need to add Black into the equation. which is B and the sum is 70.

@@kingthief9118 You can combine the 2B and B to 3B so you get "3B-5=70" then you do the opposite Operation of -5 (which is +5) to get rid of it and end up with "3B=75" then only divide by 3 to get a singular B (because 3B=3*B and therefore the opposite Operation is Division) and you get "B=25" (because 75:3=25)

Wth is dmx?​@@aca4262

What grade? Just curious so I know what to look forward to.

Lmaooo

i feel you

Same

R u now knowing

@@NancyAdomahFokuo yes, fortunately

x = 3y

2R + 3J =68 (substituting) 2*(10) + 3*(16)=68 20 + 48 =68 68 = 68 (the problem says that this formula: 2R + 3J ... gives you 68, does that make sense?)

@@mrs-junose yes thanks

You have to use the doomsday algorithm to donate some fibanchi numbers through the square terms to the power of 32 in particular to have a fighting chance. But maybe slash square root of milk powder followed by a cow whooohhehe and you're good and on your way to generating a fibanchi equation sequence good luck brother and one more thing. JESUS.

A multiple of 3 doesn't specifically mean it is a number Multiplied by 3, rather the number is a multiple of 3. So the number could be a 3 or a 27 or anything that is a factor of 3. hence +3 ,+6 etc.

The problem is that to actually show you how these are used in practice, would require a lot of extra background knowledge, that is beyond the scope of a general math class. This is why it is common to use these seemingly pointless riddles as a starting point to understand the concept. Here's an example problem I've had to solve for a real world application. A beam is 10 feet long, and supports a uniform load. It needs to be supported at two points along its length. Determine the locations of the supports to maximize its strength. This is a problem that you can solve with the tenants of Algebra 1, if you are given the theory behind it worked out for you. You'll end up solving the following system of equations, for span s and equal cantilevers of c: c^2/2 = s^2/8 - c^2/2 2*c + s = 10 The solution: s = 10*(2 - sqrt(2)) = 5.86 ft c = 10*(sqrt(2) - 1)/2 = 2.06 ft However, this is sophomore-in-college level background material that you'd need to know, to be able to set this up from first principles, and understand why the equations apply to the situation the way that they do.

Sorry forget that comment|!

Lol, that is what i was thinking, glad someone said it 😂

Yes she is. 12 * 2 is 24 then you subtract 3 that gives you 21

@@bigdog3628 she just does not look like it that’s all she meant lol

I've been stucked in this lesson for hours now :)

The first statement is that she starts with b pesos. The second statement allows me to conclude that she later has b - 50 - d pesos. We only have 1 equation and 2 unknowns, which means we don't have enough information. You need at least as many equations as unknowns, to solve for them. Linear equation systems require n equations and n unknowns, and will have one set of solutions for them. While non-linear equations can have multiple solutions, and you then may need additional information to make sense of which solution counts as *the* solution.

He said, "Sally is 3 years younger THAN twice the age of Gabby" So that means we construct our equation from this information as: 2*G = S - 3

R = 2B - 5 2B - 5 + B = 70 (we don't need those brackets) 3B - 5 = 70 (2B + 1B or just B = 3B) 3B - 5 + 5 = 70 + 5 (we add 5 to both sides) 3B = 75 3B /3 = 75 / 3 (we divide both sides by 3) B = 25 R = 2 * 25 - 5 R = 50 - 5 R = 45 Hope I could answer your questions :)

a "b" essentially means 1b, so you are adding 2b + 1b which are similar in kind so they can be summed as 3b.

in (2b - 5) + b = 70 since -5 is the only whole number, you *inverse* it and it turns to 5. Then you apply that to each side's whole numbers: (2b - 5 + 5) + b = 70 + 5 becomes: (2b) + b = 75 We inverse whole numbers themselves from the side where the letters are ("b") to get rid of them from that side once they become 0.

watch one more time!

Professor Dave Explains

It might help if you specified what you don't understand. Otherwise, Prof. Dave can only point to the video as a whole instead of a specific part because it sounds like you don't understand the entire video as opposed to, say, how he managed to construct the algebraic equations from the word problems, or how he solved each equation. Being specific is important to clearing roadblocks in learning, or your teacher/teachers can't properly help you. That way, his reply of "watch one more time!" may not read as sarcastically as it looks because he basically can't tell you anything more.

@Ronald Mike same here didn't understand a thing

I think if you plug in some numbers you'll see that you're incorrect.

@@ProfessorDaveExplains sorry my bad

And that's a good thing....the earlier you learn the concepts...the more you get the time to practice....
