Answer:
See answers below
Step-by-step explanation:
T59 = a+58d = -61
T4 = a+3d = 64.
Subtract
58d-3d = -61-64
-55d = -125
d =125/55
d = 25/11
Get a;
From 2
a+3d = 64
a+3(25/11) = 64
a = 64-75/11
a = 704-75/11
a = 629/11
T23 = a+22d
T23 = 629/11+22(25/11)
T23 = 1179/11
Answer:
BC = 11
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin45° =
, then
sin 45° =
=
=
=
( cross- multiply )
BC = 11
Answer:
there cannot be any solution of the given linear equation.
Step-by-step explanation:
i) the linear equation of 18x +
= 6(3x + 25)
ii) transforming the equation to a simpler form we get
18x +
= 18x + 150 which implies that
= 150 which is not true.
iii) therefore there cannot be any solution of the given linear equation.
