Marc wants to hang four rectangular pictures in a row on a wall so that the
horizontal space between each picture is always the same. each picture has a
length or 8 inches. the wall has a length of 74 inches. if he wants to have 12
inches of horizontal wall space before the first picture and after the fourth
picture, how much space should he leave between pictures?

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

hope this !
