Description

Math Mammoth Linear Equations 1Math Mammoth Linear Equations 1 focuses on the linear equations of the types px + q = r and p(x + q) = r and best suits 7th grade mathematics studies. The book assumes that the student has already learned to solve simple one step equations (for example _6x = 24 or x + 9 = _2). The equations in this book go one step further from that, into equations that typically require two steps (occasionally more) to solve and may contain parentheses. The next step

Math Mammoth Linear Equations 1 focuses on the linear equations of the types px + q = r and p(x + q) = r and best suits 7th grade mathematics studies. The book assumes that the student has already learned to solve simple one-step equations (for example _6x = 24 or x + 9 = _2). The equations in this book go one step further from that, into equations that typically require two steps (occasionally more) to solve and may contain parentheses.

The next step after this book (in 8th grade or in an algebra 1 course) is to learn to solve complex, multi-step linear equations Ñ yet the beauty of mathematics is that even those complex equations will be able to be reduced to these simpler forms covered in this book.

The book contains several lessons where we focus writing an equation for a word problem. Students solve these word problems both using arithmetic and using an equation, comparing the solution steps.

There is also another lesson on patterns of growth, which may seem to be simply a fascinating topic, but in reality presents the fundamentals of a very important concept in algebra_that of linear functions (although they are not mentioned by that name).

After the section about equations, the text presents the basics of inequalities and how to graph them on a number line. Students apply the principles for solving equations to solve simple inequalities and word problems that involve inequalities.

The equations in this book are limited in complexity, with the variable on one side only, and usually only requiring two (sometimes three) steps to solve. In 8th grade, or in an algebra course, students solve multi-step linear equations, including those with the variable on both sides of the equation, thus completing their understanding of how to solve linear equations.

Heavy duty legs for table.
Size: side table leg
Perfect legs for a table I am having made. I have an cottonwood slice. It's heavy and needed something substantial. These are perfect.

Robust pipe & fittings with a beautiful, smooth black finish
Size: side table leg
This set of pipe & fittings for use as low table legs is heavy duty and aesthetically pleasing. Especially when the pieces are handled, the tactile sensation is much nicer than with plumbing steel pipe because this product is beautifully finished smooth. The black pipes are quite smooth as well as the fittings. The pieces are all also pretty robust, though the wall thicknesses are less than in pipe for pressurized water systems. Of course that makes sense as this product does not need to hold fluid pressure. In my view they got the heaviness factor of this product just right; it's not as heavy or robust as black pipe used in natural gas supplies, but still robust and pretty heavy. Assembled, this product is absolutely stiff and unyielding for a solid table that could hold a man's weight easily. The feet utilize a brilliant scheme so that each foot can be independently adjusted for an uneven floor. Thus a level table on an uneven floor is easily accomplished. The feet simply extend the effective leg length by screwing counter-clockwise. To prevent any shifting at the threads adding some pipe compound or teflon tape may be advised. Even masking or duct tape might work as the idea is to just fill any gaps where male threads meet female threads. The four flanges at the tops of the legs provide a wide, solid surface for attaching the table top, with either hidden screws underneath or you could through-bolt a glass table top (provided you have the skill to drill glass!). I think this product would look great with a glass top. Assembly is quick and easy. The hardest part is drilling holes underneath the table top to accept screws. No pipe wrenches are needed as the pieces screw together by hand to an adequate tightness. If any doubt whether they are tightened enough have a strong person with grippy gloves finish. The "X" in the center attaches to the legs with a very clever machine screw system tightened with the included hex wrench. This is presumably because if tightened simply by screwing the fittings, the point of snugness would not likely be where the "T" fittings are exactly vertical. The maker has solved this problem so that you are assured that all legs will be in the perfect vertical position once everything is tight. The setup is also nice and rigid once tightened. This is a huge benefit of steel pipe projects; they are really solid. The black finish is clearly very durable, like a powder coat. It appears that it will provide excellent protection against rust. Coverage is complete; I found no dings or scratches anywhere on any piece. Overall this is a very well-designed product for function and aesthetics. Perfect for a beautifully renovated warehouse condo where an industrial vibe is desired in a rock-solid table that won't shift around. The smoothness of the pipe is top notch. I've used lots of pipe in projects, some of it actual water pipe and some decorative pipe such as this. I've never seen better quality decorative pipe as this maker put in the effort to finish it beautifully smooth. At currently $34.99 I find the price quite reasonable too.

Good DIY Pipe Legs but Powder Coat Quality Lacks
Size: side table leg, Size: side table leg
These industrial style pipe legs make building a DIY end table easy and the kit saves a trip to the hardware store. The fittings go together normally and assembly is simple. Comes individually wrapped. My main issue is the powder coating looks and feels cheap and rubs off easily. The pipes already had marks from touching each other from unboxing. If you do not mind some wear on the finish over time this is a decent purchase. The metal at the hardware store will be thicker and more durable but will cost more. I’d recommend based on ease of having a kit and it being delivered saving me a trip.

Stable, attractive, and easy to turn into a table with your choice of top
Size: side table leg
The X-shape of the table legs - constructed with solid metal flanges, T-joints, X-joints and 1-inch diameter pipes - provides a strong and sturdy base for a wood top. The legs have adjustable feet pads to prevent scratches and ensure stability. Assembly of the legs is relatively simple (the instructions are clear) but you will need your own tools to attach a top. The industrial design is especially well suited to rec room or finished basement use. I am adding a 28" diameter raw edge slab of wood from a recently felled tree as the top and it is very attractive. (Photo unavailable because after I made certain it would work I sent the slab out for drying and finishing.) If you want a custom table and have a particular piece of wood you want to use, these legs are an excellent choice.
