Answer:
1. 15
2. 8
Step-by-step explanation:
The two sequence are geometric progression GP, because they follow a constant multiple (common ratio)
The nth term of a GP is;
Tn = ar^(n-1)
Where;
a = first term
r = common ratio
For the first sequence;
The common ratio r is
r = T3/T2 = 540/90 = 6
r = 6
T2 = ar^(2-1) = ar
T2 = 90 = ar
Substituting the values of r;
90 = a × 6
a = 90/6
a = 15
First term = 15
2. The sam method applies here.
Common ratio r = T3/T2 = 128/32 = 4
r = 4
T2 = ar^(2-1) = ar
T2 = 32 = ar
Substituting the values of r;
32 = a × 4
a = 32/4
a = 8
First term = 8
1 oz = 0.0625 lbs or 1/16 lbs
1 lb = 16 oz

Answer:
(-3,5)
Step-by-step explanation:
4x + 3y = 3
x − 3y = −18
Solve by addition/Elimination
x = -3
y = 5
So,
The solution of the system is (-3,5).

Bearing means there is a rightangled triangle so
we've got an angle of 90°
an angle of 50°
sum triangle is 180
180- (90 + 50 )
= 180 - 140
= 40°
