A) 4x + 5y = 13

Mathematics
1 answer:

Answer:

C) 20x + 25y = 65

−20x + 16y = 64

Explanation:

These two systems are relatively proportionate to each other because the bottom equation was multiplied by −2, while the top equation was multiplied by 5 in order to get two <em>additive-inverse</em><em> </em>coefficients to eliminate with their variables, which in this case are −20x and 20x. Additive inverses result in zero.

I am joyous to assist you anytime.

WILL GIVE BRAINLY Find the perimeter of the figure below, in meters.
yan [13]

Answer:

147.6\:\mathrm

Step-by-step explanation:

The perimeter of a polygon is simply sum of the lengths of all sides of the polygon.

Therefore, we can find this polygon's perimeter by adding up the length of each of its sides:

9.8+9.8+11.7+9.8+21.5+21+11.7+9.8+31.3+11.2=\boxed{147.6\:\mathrm{m}}

Since there is a lot to keep track of, I'd recommend picking any side and moving clockwise/counter-clockwise until you get all sides.
