Answer:
x = -1
Step-by-step explanation:
since the 23 is positive you have to subtract it on both sides . which would give you -4x =4
then divide -4 on each side and you should get x = -1
a positive divided by a negative is always negative.
Answer:
a. 360.323 m
b. 
Step-by-step explanation:
Distance covered from A to B = speed x time
= 110 x 2.8
= 308 m
Distance covered from B to C = speed x time
= 110 x 1.7
= 187 m
The sum of angles at B =
+ 
= 
a. The distance of the plane from it starting point to C can be determined by applying the cosine rule.
=
+
- 2ac Cos B
Sot hat;
=
+
- 2(187 x 308) Cos 
But, Cos
= 0
So that,
=
+ 
= 34969 + 94864
= 129833
b = 
= 360.323
The distance from A to C is 360.323 m.
b. Applying the sine rule;
=
=
=
Sin A = 
= 0.5190
⇒ A =
0.5190
= 
The bearing of the plane from its original location =
+ 
=

Answer:
14n - 29
Step-by-step explanation:
First you'd distribute in the parentheses by -5. -5 × -2.4n and -5 × 4 which you would get 12 and -20.
Then, bring everything down and combine like terms. 2n + 12n = 14n || -9 - 20 or -9 - (-20) = -29. 14n - 29 is the lowest you can simplify because you can subtract a variable and a constant together.
