Answer:
Step-by-step explanation:
6x + 5y = 5 -----(1)
9x - 4y = 19 -----(2)
Multiply (1) by 9 : 54x + 45y = 45 ------(3)
Multiply (2) by 6 : 54x - 24y = 114 -------(4)
(3) - (4) ==> 69y = -69
y = -1
Substitute y = -1 in (1)
6x + 5(-1) = 5
6x - 5 = 5
6x = 5 + 5
6x = 10
6x=55y
9x=188y
sure it is concurent equation

Answer:
V = 3053.63 mm^3
Step-by-step explanation:
radius : 9mm
V = 4/3 * pi * r^3
V = 4/3 * (3.1415926535898...) * 9^3
V = 3053.63 mm^3
1/2 divided by 1/6 is 3

1/2 x 6/1=3
1x6=6
2x1=2
6/2=3
2.52 * 27.94 = 70.4088, so not that one
94.1 * 2.5 = 235.25, so not that one
1.83 * 2.9 = 5.307, so not that one
25.07 * 5.4 = 135.378, so that one
Answer:
D. 25.07 * 5.4 = 135.378
