Answer:
x=3
y=11
Step-by-step explanation:
y = 3x + 2 equation 1
y = 7x - 10 equation 2
using equation 1 in equation 2 we have:
3x + 2 = 7x - 10
2=7x - 3x -10
2 = 4x -10
2+10 = 4x
12= 4x
12/4 = x
we have:
x= 3
using equation 1:
y = 3x + 2
y= 3(3)+2
y=9+2
y=11
4.5 feet is 54 inches, and 127cm is 50 inches, so 50+54=104inches
(4/3) Pi r^3 = (1/3) Pi r^2 h
Solving for h = 4r
We know that
in the figure <span>equivalent ratios are
</span>BS/BC
and
AR/AC
therefore
AR/RC is not equivalent
the answer is
AR/RC
