A coefficient is the number attached to a variable (k). In front of k is an implied 1 because k*1=k. So the coefficient of the third terms is 1
Your first equation would be:
65 + 3x - 10 + 2x = 180
Then simplify to get:
5x + 55 = 180
Subtract 55 from each side:
5x = 125
Now divide by 5 to find x:
x = 25
The measure of angle B = 65
The measure of angle C = 50

Answer: <u>110 feet per second</u>
Step-by-step explanation:
In this problem we will assume that the car at 45 miles per hour is moving into the x direction with a high of 100 feet, and the train is going in the y direction, so they trajectories will made an angle of 90º.
Now we can calculate the speed of the trains in feet per second so:


So we can make a right triangle with sides 66 and 88 and the hypotenuse will be the rate that the trains will separate per second so:


Is important to have in mind that the initial high is not going to change how fast the trains will separate, however, if we are going to calculate the distance we should have it in the calculations.
Answer:
answer would be E. 16,000,000
Step-by-step explanation:
if you put 8,180 x 2,099 in the calculator you get 17,169,820
just round that number and you get 16,000,000

Answer:
4,321
Step-by-step explanation:
This is the answer because:
1) We know that if the number has to be big therefore, we have to put 4 in the thousands place because 4 is bigger than 3, 2, and 1
2) Next, 3 is the other biggest number, for that reason 3 is in the hundreds place
3) Then, 2 is the other bigger number; therefore, the tens place is 2
4) Finally, the last number remaining is 1, which is in the ones place
Therefore, the answer is 4,321
Hope this helps!
