7x - y= -5. Standard form is when it is written with x and y on the same side, but x is not negative or a fraction. To find the slope and y intercept, you must change the first two equations to slope intercept. You get y=7x-5 for the first one and y=11/3x+5 for the seccond equation. Take the 5 as your y intercept and the 7 as your slope and you get y=7x+5. Now you need to change it into standard form. When all is said and done, your final answer should be 7x - y = -5.
5/8 = 0.625
To turn a decimal into a fraction, move the decimal point two spaces to the right.
0.625 = 62.5%
62.5% of the pieces are used for the background
240 is 240% of 576
240% x 240 = x
(240 x 240) divide by 100
57,600 divide by 100 = 576
x = 576
