Answer:
perpendicular
Step-by-step explanation:
separate the two equations
First equation in the form y=mx+c
4y=2x+3z
y=1/2x+3/4z
second equation in the form y=mx+c
8y=3-5x-10z
y=3/8-5/8x-10/8z
Luke earned $54 for 3 lawns
So each lawn = $54/3 = $18
After mowing 7 lawns =
7 X $18 = $126
It would increase the average, just by a bit.
Answer:
Yes; the corresponding sides are proportional
Step-by-step explanation:
If two figures are similar, the lengths of their sides are proportional. This means if we set up a proportion with the sides we are given and cross-multiply, we get a true statement at the end of it.
Using the similarity statement ABCD~EFGH, we will compare AB to EF and BC to FG:
5/3 = 25/15
Cross multiply:
5(15) = 3(25)
75 = 75
We got a true statement, so the sides are proportional.
