Answer:
64
Step-by-step explanation:
5x-16+6x=10x (combine like terms)
11x-16=10x (subtract 11x)
-16= -1x (divide by -1
16 = x
Now plug 16 into 5x-16.
5(16)-16 = 80-16 = 64

Answer:
(b) 9
Step-by-step explanation:
The product of segment lengths to the near and far intersection with the circle is the same for both secants.
4(4+5) = 3(3+x) . . . . the above statement with numbers filled in
36 = 9 +3x . . . . . . . simplify
12 = 3 +x . . . . . . . . divide by 3
9 = x . . . . . . . . . . . subtract 3
Answer:
CN Tower = 550 m and church tower = 160 m
Step-by-step explanation:
The first equation x + y = 710 is correct
but the second one is
x - y = 390
Note x = height of the CN tower and y = height of the church.
x + y = 710
x - y = 390
If we add the 2 above equations we eliminate y so
2x = 1100
x = 550 m
and y = 710 - 550 = 160 m
-4e-9=19
+9+9
-4e=28
e=7
-4x7=28
so its e=7
