Since <span>BC ∥ DE, we only apply thales theorem, it is
AB / AD = AC / AE, so we can find directly AE , </span>AB / AD = AC / AE implies AB x AE = AC x AD and AC= AB x AE <span> / AD= 12 x 3 /2=18
</span>since AC= 18, and AC=AE+CE, so we can get CE= AC - AE=18-3=15
CE=15cm
Answer:
y=-2x
Step-by-step explanation:
Max mows a yard in 45 minutes and Jan takes twice as long mowing the same yard. If Max and Jan both work together, it will take approximately 30 minutes to for them both to mow the yard.
It take Max 1 minute to mow 1/45 of the yard.
It takes Jan 1 minute to mow 1/90 of the yard.
1/45+1/90 =3/90 = 1/30 of the yard can be mowed by both in just one minute. This is how to get the answer, 30 minutes.
