<span>3 - (2x + 4) = 2(x - 4.5)
3 - 2x - 4 = 2x - 9
4x = 8
x = 2</span>
Volume is V=πr^2
so just plug it in hun,
9) 134.04 m
10)167.55 cm
11)11150.55 m
12)100.53 yd
13) 1256.64 m
14)1526.81 yd
15)103.67 m
16)117.29 ft
Hope this helps
Answer:
Since one equation already has one variable isolated(x), it gives you a "value" to input into the other equation to use to solve for the other variable(y).
10(y-3) + 10y = 1
10y - 30 + 10y = 1
20y - 30 = 1
20y = 31
y = 31/20 or 1.55
Now you can use this value to solve for x in one of the original equations.
x = (31/20) - 3
x = -29/30 or -1.45
Hope this helps!
