Answer:
751.8
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>
250/5 = 50
therefore they must wash at least 50 cars
Answer:
x=5
Step-by-step explanation:
I'm pretty sure it's x=5 because if you multiply that and the quadratic function it is -12 1/2 not 12 1/2 (hope this helps :)
7, to find the mean add up all the numbers and then subtract by the amount of Humber a you added.
For example, 1,3,8,10 added together is 22. We added four numbers together, so divide by 4. The mean of 1,3,8,10 is 5.5
