A man had 15 crates of apples. Each crate had the same number of apples. He sold 70 apples on Monday and twice as many apples on Tuesday. He had 90 apples left. How many apples were there in each crate at first?

=20 apples

Step-by-step explanation:

90+70+140=300

300 crates in total

300÷15=20

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

step-by-step explanation:

no solution.
