Answer: OPTION B
Step-by-step explanation:
Let's call:
c: the number of cars.
m: the number of motorcycles.
Based on the given information, you can set up the following system of equations:
You can solve it by the Elimination method:
- Multiply the first equation by -4.
- Add both equations to cancel out the variable "c".
- Solve for "m":
(24 motorcycles)
- Substitute m=24 into any of the original equations ans solve for "c". Then:
(14 cars)
The magnitude of the tension on the ends of the clothesline is mathematically given as
T= 47.6194N
<h3>What is the magnitude of the tension on the ends of the clothesline?</h3>
Generally, the equation for AB^2 is mathematically given as
AB² = AQ² +BQ²
Therefore
AB²=5²+32
AB² = 25+9
AB² = 34
AB=√34
sin ∅ = ав AB
Sin∅ = 3 √34
Let T1 and T₂ be tension in AB and BC respectively
The horizontal component of tension. T1 cos∅ = T₂cos ∅
T₁ = T₂
The vertical component of tension
T1 sin∅. + T₂ sin ∅ = mg
Tsin∅+ Tsin∅ = mg
T = mg/2sin∅
T=5*9.82/ 2 sin ∅
T= 47.6194N
In conclusion, the magnitude of the tension
T= 47.6194N

Answer:
Step-by-step explanation:
It will never be positive becasue there is a negitive sign in the equation. negitives overule positives. Therefor it will never be positive.
-7 =
+ 14
take 14 to the other side
-7 -(14) =
-21 =
Multiply by 3 on either sides to isolate e and to find a value
-21 × 3 =
× 3
3 and 3 cancels out
-63 = e
