Step-by-step explanation:
-5x+8y=-4
6x-8y=-12 8y and 8x cancel out
x=-16
To solve for y, substitute x=-16 back into the first equation
-5(-16)+8y=-4
80+8y=-4
8y=-84
y=-10.5
55h + 40 = 190.
55h = 150.
h = 2.73
Answer:
52pi
Step-by-step explanation:
You need the area of the large grey circle, minus the white circle, plus the small grey
Large grey = 8^2 * pi = 64pi
White = 4^2 * pi = 16pi
Small grey = 2^2 * pi = 4pi
64pi - 16pi = 48pi, 48pi + 4pi = 52pi
Got it :)Thank you!!!!!!!
To find the answer,we can divide the arches(210) bythe amount a cattle need( 1/3):
210÷1/3
=210×3
=630
Therefore, the farmland could support 630 cattles.
Hope it helps!
