We will be solving equations all year long, and this will continue throughout all of your future mathematics courses.
1. Out of all of the equations we've solved in this chapter, what is the most difficult type for you to solve? (If everything feels easy to you, what do you think is the most difficult out of the easier problems?)
2. Now invent an equation that you think would be tough for most of the students in the class to solve. Then solve it. Be very careful to make sure that you write the equation correctly using the keyboard. Post the equation and its solution in this same blog.
I think its the fraction and decimal because it is very annoying to solve fraction and decimals. (especially decimals)
ReplyDelete-This is a hard problem.
6-4x(1.5x-2x)=42-(3x^2+50)+3x^2-23
1. The most difficult equation for me was making the equation into multiplication.
ReplyDelete2. Will.i.am and his group needed money for their concert. Will.i.am needed 200,000 dollars to make a concert. Each ticket costs 35 dollars. How many tickets need to be sold approximately?(Round to the nearest hundredths)
ANSWER: $5714.29
1.The inequality because its confusing to tell which direction to go like x>25
ReplyDelete2.Question: X≠10
Answer:<------ㅣ------->
<-----10------->
1. I think the most difficult equation for me was Problem Solving Shapes perimeter and area because sometimes i dont understand what something the question means. I also think that if you mess up and on ting, then everything will be messed up so i was nervous in test.
ReplyDelete2. A Rectangle has a length of x and the with 6 less than x. Solve the x and find the perimeter and area of the rectangle.
I think that the hardest concept I have come across so far is graphing inequalities. I think that it is very confusing and I get confused were to put the arrows direction.
ReplyDelete_11________12_______13________14________15______16
<----------------o
Solve this inequality and then graph.
15-2 > x
I think the most difficult for me is the decimals and fraction equations, Because if you don't organize it neatly you get lost while answering the questions or you can make calculating errors.
ReplyDeleteHere's one example of an easy, but annoying equation.
Solve the equation below.(made up)
6.5+1/2+2/5x(1/7+5.9(9.7))+5.3x-3.4x
I think the hardest kind for me was multi-step equations, because it was not very easy to show each step accurately. Also, you have to show a LOT of work.
ReplyDeleteHard Equation: Donald the Duck swam down the river for 35ft. And then, he swam up the river for 76 ft. Then, he fainted and floated around for X feet. Later, he found out that he traveled for 1456 ft. How much did duck travel when he was floating around?
Answer: He travel for 1345 ft.
1. The most difficult for me was the inequalities because you had to remember that the inequality sign flips when you multiply or divide by a negative number. Also the direction of the arrow and the circle were confusing sometimes.
ReplyDelete2. 84<x/6+83.9
Answer: 84-83.9<x/6+83.9-83.9 0.1•6<x/6•6 0.6<x
I think it was the hardest to solve an equation with decimals. It is because, it is harder to organize and be accurate.
ReplyDeleteHere is a problem that you can solve.
A perimeter of a triangle is 186cm. The length as n cm and width as n+9 cm. what is the area of this triangle?
I think the hardest part was between negative and positive because I get really confused and negative look like minus...
ReplyDeleteI think the hardest problem is those mistorical questions
that is made like in 1600s.
The most difficult equation was that friction which has the x and plus that friction. (9xover 8+2=3). This equation make me confused. I didn't know which one should I solve it first. Friction first or the plus things one.. So at first, I solve the plus thing first. But I was wrong.So at the fist time, I didn't know what should I solve it first.
ReplyDeleteSolve the equation:
5x(5-6)+[6y(5-7)+5y]-9x=
Answer=16x+35y-65
1. For me the most difficult thing was drawing the graph for the inequalities. Sometimes I don't know which side to put the arrow. Or sometimes I get the solving part wrong so I can't graph it sometimes.
ReplyDelete2. 15-2x + 14 -16 > 39
Solve, and graph.
I think that the hardest part about solving problems is solving with decimals, fractions because there are chances you can make careless mistakes.
ReplyDeleteFor example, 3.59*5.2(4.3+2.3)
The Answer would be 123.2088
I think it was the hardest to solve an equation with decimals. It is because, it is harder to organize and be accurate.

A perimeter of a triangle is 186cm. The length as n cm and width as n+9 cm. what is the area of this triangle?
Answer: 2226cm2
The most difficult thing in this chapter was inequalities. I got confused when we had to change the inequality sign. I think it was hard for me because I wasn't able to get used to these formulas easily.
ReplyDeleteThis is a sample problem that might be tough for students to solve.
2x≤x-1<2x+3
Answer: -4<x≤-1
The answer to the expression, Not an equation is 7.
ReplyDelete1. Out of all of the equations we've solved in this chapter, what is the most difficult type for you to solve? (If everything feels easy to you, what do you think is the most difficult out of the easier problems?)
ReplyDeletemost likely the two step equations with inequality's
2. Now invent an equation that you think would be tough for most of the students in the class to solve. Then solve it. Be very careful to make sure that you write the equation correctly using the keyboard. Post the equation and its solution in this same blog.
I think x>9*57+237-3+4*7-8/7
Awncer is x=751
I think most difficult equation was equation with variables and inequality. Inequality made me more confusing.
ReplyDelete6n-33+15>60
n>13
I think the most difficult type for me is inequalities because I never learnt it before. I always made mistakes when we had to flip the sign, such as forgetting to or flipping when I wasn't supposed to. I also had a little trouble with the word problem sometimes, especially the one's that had something to do with distance.
ReplyDeleteProblem : -42y ≤ -378+5(124)+1.6
Answer: y ≥ -5.8
The most difficult thing that I learned from this chapter is the inequalities. I understand how to solve it, but graphing the negative is very difficult to me.
ReplyDeleteSome question would be like this :
Answer this question
8x< -56 ? graph this solution
Answer. :
x< -7
<- - ->
-8-7-6

Hey guys,
ReplyDeleteJust so you know, if you solved your equation incorrectly, you received two points off of this blog post.
