Answer:
A≈176.71
Step-by-step explanation:
Because two angles are equal, sides AB and AC will have equal lengths, and so, we can set each expression equal to each-other.
4x + 4 = 6x - 14
Subtract 4x from both sides.
4 = 2x - 14
Add 14 to both sides.
18 = 2x
Divide both sides by 2.
x = 9.
Because we have a constant value of x, we can solve for BC.
BC = 2x + 7
2(9) + 7
18 + 7
25
<h3>The value of BC is 25.</h3>
The answer is B. Quadrant II

Answer:
7.5% error
Step-by-step explanation:
Percent Error = ( | measured - real | / real ) x 100%
|430 - 400| / 400 = |-30| / 400
( 30 / 400 ) x 100%
= 7.5%
The number of cars, vans and trucks rented are;
Number of Cars = 4 cars
Number of vans = 36 vans
Number of trucks = 108 trucks
<h3>How to solve Algebra Word Problems?</h3>
We are given;
Total number of vehicles = 155 vehicles
Let number of cars be x.
Thus, since Nine times as many cars were rented as vans, we have;
Number of vans rented = 9x
Now, three times as many vans were rented as trucks. Thus;
The number of trucks rented during one month = 3(9x)
Thus;
x + 9x + 27x = 155
37x = 155
x ≈ 4 cars
Number of vans = 9 * 4 = 36 vans
Number of trucks = 3 * 36 = 108 trucks
