Hey im having problems with a math problem and i don't get it. does anyone know the answer? i'll praise you if you do: ) the problem: is 0.25x+0.05y=1.00

the answer for your question is y=20

First solve for x isolating, to do so subtract .05y from each side leaving the equation as .25x=(-.05y)+4

Then multiply each side by 4 leaving the equation as x= (-.2y)+4

Then isolate do the same to solve for y, start with the equation, 0.25x+0.05y=1.00 subtract .25x from each side leaving the equation as

.05y= (-.25x)+1

Then multiply each side by 20 leaving the equation as y= (-5)+20

So x=(-.2)+4 and y=(-5)+20

Another way to solve this would be to set x equal to 0 and solve for y this gives the equation .05y=1 then divide each side by .05 giving the answer y=20

Then set y equal to 0 leaving the equation .25x=1 then divide each side by .25 leaving the answer as x=4

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
