Best Friends Share Desserts

Best Friends Share Desserts is an acrinume to soving fractional equations. the b stands for brackets so first you look for any brackets and if there are brackets then you need to solve them. the f stands for fractions which means your next step if to getting rid of the fractions by finding a common denominator then mutipling the numerator by the common denominat0r then divideing the nemerator by the denominator. the s stands for sort because you have to create zero pairs. the d stands for divide meaning you have to divide both numbers you are left with by the coeficent.

Linear Relations

if you have a pattern of 2,4,6,8 and you want to find the equation so you can graph it. first you find out how much the pattern is going up by. For example my pattern goes up by 2 then you are going to put 2 times x. x is representing the term number. Then you test your equation and see how much more you need to subtract or add to get the correct answer so 2 times term is equal to 2 so you don’t have to add or subtract in this case. so my final equation is 2x.image

Surface Area

i learned how to connect shapes and then add the two surface areas together then take away the base x2 to find the total surface area of the connected shapes. I also learned that by creating a hole through a shape you are adding surface area. Another thing I learned is all the formulas to find surface areas of 3d shapes. Triangular prism = adding all individual sides together rectangular prism = 2(lxw+wxh+Lxh) cylinder = 2xpiexrxh + 2xpie x r to the power of 2. I found that it was really hard because if you got one little calculation wrong then the hole question was wrong. I did find memorizing the formulas and showing my work very easy though.

How to use algebra tiles

each tile represents something and when you put the tiles side by side you are creating a equation. you can put a tile with it’s coloured side facing up and this would be a positive number witch means you are adding. If you put the tile down with its white side facing up it means that it is a negativE number which means you are subtracting it. then you group the equation for example the x to the power of twos would all go together and all the x would go togeter and the single units. Once you are done that you are going to simplify so create zero pairs. if you make a zero pair then u move those tiles to the side then you are left with your simplified anwser.
