Make use of the fact that side lengths in similar triangles are proportional.
.. 30/18 = (20 +x)/20
.. 20*(30/18) -20 = x . . . . multiply by 20, subtract 20
.. 33 1/3 -20 = x . . . . . . . . evaluate the product
.. 13 1/3 = x
You simply have to multiply
if there is 7 apples on monday
and 3 times as many/x
7x3=21
Answer:
For option 3, y=4/3x +4 is a linear equation. To graph this equation, you want to start at (0,4) on the y-axis because that is your y-intercept.
